SECTION 1: INTRODUCTION

This Installation and User’s Guide includes all the information you need to safely and efficiently install, operate and maintain your MAXX-1100 Laser Alignment System.

The Treatment Room Moving Laser Patient Positioning System consists of one to three MAXX-1100 units; the Maxx-1100 Unit(s) is connected to a central system controller. Operators interface with the controller using a remote control. The controller can also be configured for a network interface to the treatment planning system.

The purpose of this manual is to provide instructions on the installation and setup of the moving lasers within the treatment room. This manual also includes basic operating instructions for the MAXX-1100 Unit, its Controller, and its computer software system.

This Installation and Set-up Manual pertains to Revision 1.1.4, of the MAXX-1100 Unit. Please make sure that your remote control and all the documents have the same revision number.

Page | 8

SECTION 2: SYSTEM OVERVIEW

The MAXX-1100 laser system consists of several moveable crosshair lasers, a handheld remote control, and a PC controller, operated by a comprehensive software system. The lasers within the MAXX-1100 define the planes of the treatment room.

Within an appropriately established treatment room, the MAXX-1100 permits the successful preparation and treatment of patients via radiation therapy. The lasers are adjusted to the offset point of the treatment room. Offset points allow medical personnel easy access to the patient for marking purposes. This system allows medical personnel and system operators to directly identify tumour locations and mark patients for treatment.

Note: Use of the MAXX-1100 laser system other than its intended use is carried out entirely at the user's risk.

SECTION 3: LASER SAFETY CONSIDERATIONS

3.1 GENERAL SAFETY

To help ensure safe operation of your MAXX-1100 system, please read this section carefully and follow the instructions and procedures in this manual before installing and operating the units.

At all times during installation, operation, or adjustment of a MAXX-1100 unit avoid staring into the beams or other sources of bright light emanating from the unit. The MAXX-1100 is a class ll 1mW laser. The American National Standards Institute (ANSI) notes that Class 2 lasers are CW and repetitively pulsed lasers with wavelengths between 0.4 µm and 0.7 µm that can emit energy in excess of the Class 1 AEL, but do not exceed the Class 1 AEL for an emission duration less than 0.25 seconds and have an average radiant power of 1mW or less.

Should adjustment or alignment be necessary at any time once the laser is activated the patient’s eyes should be protected.

3.2 SAFETY, FUNCTIONALITY, and MAINTENANCE

For accuracy integrity, Isocentre of diagnostic and treatment equipment must match the Isocentre of alignment lasers.

All positioning equipment in the treatment room should be measured at least twice: once upon initial installation and once before service to ensure that construction materials in the walls, floor, and ceiling have settled into position. Realign lasers to Isocentre before use, if they have moved.

Testing the alignment of lasers to Isocentre of diagnostic or treatment equipment is based on hospital procedures.

The MAXX-1100 is a class ll 1mW laser. Replace laser diode only with assembly provided by Cemar Electro Inc. to ensure that laser power levels do not exceed class ll 1mW limits.

The Maxx-1100 unit is virtually maintenance free requiring only visual inspection and cleaning of the encoder glass annually (with a dry lint free cloth) the exterior can be cleaned with a damp cloth.

3.5 PROTECTIVE EYEWEAR

Protective eyewear is not necessary for typical applications where direct papillary impingement by the beams is a random momentary event. Under typical conditions requiring more protracted ocular exposure, protective eyewear or other protective measures may be required. Consult the user standards of the ANSI for further guidance (https://www.rli.com/resources/articles/classification.aspx).

3.6STORAGE

To ensure optimal functionality of the MAXX-1100 unit, ensure the following:

• Do not drop

• Store all components in a non-corrosive environment

• Maintain storage temperature between -20°C and +75°C (-4° F and167° F)

• Maintain storage humidity between 20% and 85% relative humidity. Do not permit dew condensation

SECTION 4: SYSTEM COMPONENTS

The overview of the system configuration for the MAXX-1100 is shown in Figure 4.1. The configuration table should be completed at the time of purchase. Before beginning installation of the laser system, verify that all components shown on the system configuration chart have been provided. If any required system components are missing, please contact Cemar Electro Inc. immediately for assistance.

A description of the major system components in a moving laser patient positioning system is given in the following paragraphs. Figure 4.1 shows the typical system components.

4.1 MAXX-1100 Unit

Each Maxx-1100 unit can generate three orthogonal laser lines, one perpendicular to the long axis of the Maxx-1100 unit frame, and two parallel to the long axis of the Maxx-1100 unit frame. 7120

Figure 4.1 System Components

Page | 14

Moving laser: The line perpendicular to the long axis of the Maxx-1100 unit frame is generated by a diode that can be moved along the long axis of the actuator. It has a linear movement of +/-300mm from the laser travel zero. (Figure 4.2)

Fixed laser(s): (Optional) The line(s) parallel to the long axis of the Maxx-1100 unit frame is generated by a laser diode that is fixed in position at one (or both ends) end of the actuator. Also has a manual linear adjustment of +/-10mm from the centre point. (Figure 4.2)

Each Maxx-1100 unit has an identity in the system, and can be used as a single unit system, a two unit system, or a complete three unit system. (Figure 4.1)

Z Actuator: The Z actuators are located on either side of the treatment couch, and are referred to Maxx-1100 unit 1 or Maxx-1100 unit 2.

X Actuator: The X actuator is mounted directly over the isocenter point, and is referred to Maxx-1100 unit 3.

4.1.1 LASER LINE ADJUSTMENT

Proper alignment of the laser lines requires precise adjustment of the laser lines within the confines of the treatment room. Two adjustments are possible for each laser diode, namely, tilt adjustment and rotation adjustment. (Figure 4.2)

4.1.1.1 TILT ADJUSTMENT

Tilt adjustment allows the laser line to pivot from end to end for the moving laser, adjusting the positioning relative to the moving axis of the Maxx-1100 unit, and side to side for the fixed laser relative to the moving axis of the Maxx-1100 unit. (Figure 4.2)

4.1.1.2 ROTATION ADJUSTMENT

For the moving laser the rotation adjustment alters the angle of the laser line to be parallel to the moving axis of the Maxx-1100 unit by rotating the laser diode. The rotation adjustment alters the fixed laser line angle so that it is perpendicular to the moving laser. (Figure 4.2)

4.2 SYSTEM CONTROLLER PC. (Optional)

The system controller (PC) can control multiple-axis configurations, allowing the movement of up to three Maxx-1100 units. All controllers include a Monitor, a router, and all necessary cabling. (Figure 7.1)

Page | 15

4.2.1 CONTROLLER CONNECTIONS

The system controller has a multiple output router; this is used to communicate with each Maxx-1100 unit which are connected to the router with a Cat6 cable. (Figure 7.1)

SECTION 5: TREATMENT ROOM PREPARATION

Correct treatment room set-up is crucial to the successful installation of a patient positioning system.

Preparation work on the treatment room should be completed before the system components are shipped to the installation site. Necessary preparation work comprises:

• Establishing where various system components will be located within the room

• Determining the mounting configuration for each laser unit

• Providing an adequate structure to mount all the laser units in the system

Figure 4.2 Lasers Layout and Adjustments

Page | 16

• Determining routings for cables

• Establishing necessary power for the system

In the case where the treatment room is not yet constructed, Cemar Electro Inc. recommends that a rigid steel support frame for the Maxx-1100 units is incorporated into the room construction. (Figure 5.1)

Room layout begins by identifying the location of the point in the room that will be the isocenter for the patient positioning system. (Figure 5.1)

Note: The radiographic centre point of the room is not the same as the isocenter of the laser positioning system. Both the radiographic centre and the isocenter typically have the same X and Z coordinate, their Y coordinates differ. In this manual, the isocenter will always be referred to as such.

Page | 18

Once the isocenter location has been determined, the installation location of the system lasers can be determined. (Figure 5.2)

• The X actuator (Maxx-1100 Unit #3) should ideally be mounted directly over the isocenter point, using a ceiling mount configuration with the Laser Travel Zero near to the centre of the treatment couch. This permits the X line to be viewed at consistent intensities, and full laser travel on treatment couch.

• The Z actuators (Maxx-1100 Unit #1 and Unit #2) should be located on either side of the treatment couch, aligned perpendicularly to the long side of the treatment couch, with the Laser Travel Zero near to the isocenter.

5.2 MOUNTING BASE PLATES

Steel or aluminum base plates (Hospital Contractor supplied and installed) can be located in the walls and ceiling where the laser units are to be mounted or a reasonable alternative like U-Channel. The location, size, and stability of these base plates or Channels are critical to a satisfactory installation of a moving laser system. (Figure 5.1)

Figure 5.2 Isocentre position.

Page | 19

** This rigid structure is required because any movement of the mounting structure for the Maxx-1100 unit will result in movement of the laser lines.

5.3 Maxx-1100 MOUNTING OPTIONS

Two mounting options are available for the X actuator (Unit #3) in the system. (Figure 4.1)

Option 1. The preferred option is a ceiling mount directly over the treatment couch. This allows the optional fixed laser(s) in the X actuator (Unit #3) to be aligned as part of the Y plane in the system. This permits the X line to extend unobstructed over the full length of the patient’s body.

Option 2. A second option for the X actuator (Unit #3) is a Gantry system. In this case, the X actuator (Unit #3) is mounted to the tops of the Z actuators (Unit #1 and Unit#2), but the lasers are positioned closer to the treatment couch.

There are three mounting options available for the Z actuators (Unit #1 and Unit#2) in the system. (Figure 4.1)

Option 1. If the walls of the treatment room are within 3 meters of the treatment couch, the actuators can be mounted directly to the walls.

Option 2. A second option for the Z actuators (Unit #1 and Unit#2) is a Gantry system. In this case, the Z actuators are mounted under the X actuator (Unit#3), but the lasers are positioned closer to the treatment couch.

Option 3. If the treatment couch is located far from the walls of the treatment room, a floor mount could be used for the Z actuators (Unit #1 and Unit#2).

The laser lines are pre-focused to a distance of 2 to 3 meters from the actuator. If the Z actuators must be mounted at an angle relative to the wall, or at a distance closer to the treatment Couch re-focusing may be necessary.

Finally, consider mounting the Z actuators (Unit #1 and Unit#2) on or as close to the walls as possible; this avoids possible interference with treatment room personnel.

5.3.1 CEILING MOUNT

The ceiling mount arrangement is shown in Figure 4.1.

The ceiling must feature a rigid structure (Hospital Contractor supplied and installed) within its construction. Typically, this rigid structure is a metal plate built into or affixed on the ceiling or a channel mounting system. It is to this installation that the pivot-bracket mountings (Supplied with Maxx-1100 Unit) will be connected.

Page | 20

5.3.2 WALL MOUNT

As with the ceiling, the walls must feature a rigid structure (Hospital Contractor supplied and installed) within their construction. Typically, this rigid structure is a metal plate built into or affixed to the wall or a channel mounting system to which the pivot-bracket mountings (Supplied with Maxx-1100 Unit) will be attached.

The wall mount arrangement is shown in Figure 4.1. For a wall mounting, a rigid structure is affixed to each wall.

5.3.3 FLOOR MOUNT

A Maxx-1100 unit can be secured to the floor in a vertical configuration using a floor mount pedestal (Supplied with Maxx-1100 Unit). The floor mount arrangement is shown (Figure 5.1)

Floor mounting allows lasers to be mounted vertically, but attached to the floor. This configuration is advantageous in allowing the user to easily orient the Z actuator (Unit #1 or Unit #2) at any distance with respect to the treatment couch. This is particularly convenient in treatment rooms where the couch is installed at a long distance from the walls of the room.

5.4 CABLE ROUTING (For the Optional controller)

Maxx-1100 unit in the system must be connected to the computer controller by an Ethernet cable. Cables are provided at specified lengths. Provisions should be made in the treatment room to route these cables as directly as possible to the system controller while not posing any hazard to personnel working in the room. (Figure 5.1)

Maxx-1100 unit cables may also be routed through conduit. If this is done, the conduit should be of a minimum inside diameter and any bends should be a large and gradual enough to allow the cable connectors to be pulled through the conduit without undue stress.

5.5 POWER REQUIREMENTS

For the MAXX-1100 System, a separate power outlet is required for each Maxx-1100 unit. Each Maxx-1100 unit requires 100-240VAC 1A, 50-60Hz.

The Maxx-1100 unit is equipped with a power on/off switch, but if the treatment room configuration allows, it may be desirable to install a single switch to control outlets to the units. (Figure 5.1)

If the optional system controller is used, one power outlet is required for the system controller PC. The system controller PC requires 100-240V AC 8/4A, 50-60Hz power

Detachable mains supply cords are provided, use of other detachable mains supply cord

must meet adequate ratings, (see technical Specification table).

Page | 21

SECTION 6: LASER INSTALLATION

Before the Maxx-1100 units can be correctly installed in the treatment room, the system isocenter must first be identified. Once identified, templates (Supplied with Maxx-1100 Unit) should be placed on the wall to determine the precise location of the mounting.

In the following sections on laser installation, it is assumed that a mounting base plate or alternately a Channel system (Hospital Contractor supplied and installed) has already been installed in the correct location to mount the lasers.

6.1 ESTABLISHING ISOCENTRE REFERENCE MARKS

The primary task in patient positioning system installation is establishing reference marks for each of the three planes for the lasers. (Figure 6.1)

Ideally, the X actuator and Z actuator coordinates of the laser system centre will correspond with the radiographic zero of the treatment room. Y-axis of the laser system is typically offset some distance from the centre of the radiographic scan plane (i.e., 600 mm). This offset value should be noted for future use in patient setup. (Figure 5.2)

6.2 FINDING THE TREATMENT ROOM RADIOGRAPHIC CENTRE

Three options are possible for determining the treatment room radiographic centre; options are listed in order of accuracy:

1. Using a scan to find the radiographic centre

2. Using treatment equipment’s internal lasers to find the radiographic centre

3. Using physical measurement to find the radiographic centre

Figure 6.1 Phantom overview

Page | 22

6.3 USING THE ROTATING LASER

A rotating laser can be used to establish the Y, Z, and X planes for the Maxx-1100 system based on the scan of the installation phantom. (Figure 4.1) and (Figure 6.1)

Note: When moving the phantom side to side, be careful not to change the angle of the phantom, or else the steps to align the phantom with the scan plan will need to be repeated. While performing the above scan procedures, the grooves on the sides of the phantom may not line up with the grid on the scan image (i.e., the image of the phantom is rotated relative to the grid). If this occurs, verify that the phantom is level and adjust and re-Scan as necessary. The patient positioning lasers should be installed in a coplanar orientation with no Parallax. If the image in the CT simulator is not oriented correctly with respect to the horizontal plane, it will be difficult or impossible to correctly mark and position the patient for treatment.

6.4 INSTALLING LASERS

6.4.1 FLOOR MOUNTING

A floor mount requires four studs to be installed in the floor, a floor template (Supplied with Maxx-1100 Unit) is used; wall/ceiling mounting template cannot be used. In order for the laser centre to be located in the Y reference plane, the Floor Mount Pedestal for the Maxx-1100 unit must be mounted in the correct location. (Figure 4.1)

The holes in the base plate of the pedestal are elongated to allow for some adjustment of both angle and the lateral position.

Step 1. Position the floor template so that the reference line for the centre of the laser corresponds with the line determined by the marks made on the floor to define the Maxx-1100 unit’s Y reference plane.

Step 2. Mark, drill and install mounting studs. Step 3. Place and loosely secure the Floor Mount Pedestal. Step 4. Remove front covers for the Floor Mount Pedestal and Maxx-1100 unit. Step 5. Position and mount the Maxx-1100 unit to the top of the Floor Mount

Pedestal, and secure them together using the provided 8mm bolts. Step 6. Align to the Y plane of the room; shim under the base plate as required so all

plate holes are in contact with the floor. Step 7. Tighten in this position. Repeat for other unit. Step 8. To verify that the Laser Travel Zero of the two Maxx-1100 units is aligned, use

any line-generating device to project a line on the Laser Travel Zero indicator stickers. This projected line should intersect the reference stickers, if not shims may be required if the different is more than 5mm.

Step 9. The Maxx-1100 unit is now ready to have power turned on. (Section 7)

Page | 23

Step 10. Adjust the lasers to Z and Y planes using tilt and rotation adjustments. (Section 8.2)

Step 11. Replace front covers.

Note: Before applying power to the system, remove the Maxx-1100 unit cover from each actuator and confirm that the strapping tape that secures the laser carriage during shipment has been removed.

6.4.2 WALL MOUNTING

For Pivot-bracket mounting, the laser(s) must be placed in the correct laser reference plane.

The pivot-brackets included have pivoting angles in two directions and linear adjustment slots in two directions, and an adjustment channel located in the frame of the Maxx-1100 unit. (Figure 4.1)

Step 1. Place the pivot-bracket mounting template (with Laser Travel Zero) aligned +/-5mm to isocenter.

Step 2. Mark, drill and tap holes for pivot-bracket mounting hardware (M6 bolts), if mount plate was installed. If U-channel was installed, use a M6 channel nut / strut nut to connect pivot-bracket.

Step 3. Split the pivot-bracket by removing the middle bolt. So one part is still connected to the Maxx-1100 unit and the second half is free to mount to the wall.

Step 4. After mounting the half pivot–bracket to the wall, position the Maxx-1100 unit and reconnect the halves of the pivot-bracket.

Step 5. Adjust the pivot-brackets so that the Maxx-1100 unit is square and level, and that the Laser Travel Zero is aligned to the opposite Maxx-1100 unit.

Step 6. Tighten the pivot-brackets in this position. Repeat for other unit. Step 7. To verify that the Laser Travel Zero of the two Maxx-1100 units is aligned, use

any line-generating device to project a line on the Laser Travel Zero indicator stickers. This projected line should intersect the reference stickers, if not repeat Step 5.

Step 8. The Maxx-1100 unit is now ready to have power turned on. (Section 7) Step 9. Remove front cover. Step 10. Adjust the lasers to Z and Y planes using tilt and rotation adjustments.

(Section 8.2) Step 11. Replace front covers.


Page | 24

6.4.3 CEILING MOUNTING

A ceiling mount system is required, the recommended system is U channel mount which can be installed so that its long axis is parallel to the Y line in the system and an X-Axis will give full flexibility, also a plate could be mounted to the U-channel for added support (Hospital Contractor Installed). (Figure 5.1)

The pivot-brackets included have pivoting angles in two directions and linear adjustment slots in each plate and an adjustment channel in the frame of the Maxx-1100 unit.

Step 1. Use a M6 channel nut/strut nut to connect pivot–brackets. Step 2. Split the pivot-bracket by removing the middle bolt. So one part is still

connected to the Maxx-1100 unit and the second half is free to mount to the U channel.

Step 3. After mounting the half pivot–bracket to the U channel, position the Maxx-1100 unit and reconnect the halves of the pivot-bracket.

Step 4. Adjust the pivot-brackets so that the Maxx-1100 is level in both directions, and that the Laser Travel Zero is aligned to the treatment couch centre.

Step 5. Tighten the pivot-brackets in this position. Step 6. The Maxx-1100 unit is now ready to have power turned on. (Section 7) Step 7. Remove front cover. Step 8. Adjust the lasers to X and Y planes using tilt and rotation adjustments.

(Section 8.2) Step 9. Replace front cover.


SECTION 7: MAXX-1100 CONNECTIONS

7.1 MAXX-1100 UNIT POWER-UP

Each Maxx-1100 unit has a detachable main power supply cord; the on switch is located near the entry point of this cord. Plug in unit with the switch in the off position then switch unit on.

Refer to Section 9.1.3 for the Maxx-1100 unit start sequence at power-up. Automatic power-up procedures are executed any time power is applied to the Maxx-1100 unit.

Note: The power input also contains a replaceable fuse which Cemar Electro recommends replacing with a rated 2.0A fuse.

Page | 25

Before applying power to the system, remove the Maxx-1100 unit cover from each actuator and confirm that the strapping tape that secures the laser carriage during shipment has been removed.

7.2 SYSTEM CABLE CONNECTIONS (With Optional Computer for Dicom Protocol)

Before you can finalize the install of the Maxx-1100 system the following system connections must be made, the Maxx-1100 unit(s) be powered on, and their position appropriately situated. The power cords connect to the power connection on the controller (PC) and router. The Maxx-1100 unit(s) and controller (PC); connected to the router.

The system cable connections can be seen in Figure 7.1.

7.3 SYSTEM CONTROLLER POWER-UP

The system controller provides control to the entire MAXX-1100 system. Power is applied by turning on the power switch on the control enclosure (PC); then run the Maxx-1100 control software. Power-up operations for the system controller and for the remote control are outlined in Section 9.1.3.

SECTION 8: SYSTEM ALIGNMENT

8.1 BASIC LASER ALIGNMENT CONCEPTS

The following basic principles apply to alignment of laser lines independent of the model or application. For each individual laser line, the following steps must be followed in sequence.

8.1.1 LASER ORIGIN POINT MUST BE IN THE CORRECT PLANE

The Laser Origin Point (LOP) is the point where the laser line exits the line-generating optics on the laser module. This is typically a point at the end of the laser module, in the centre of the laser diode barrel. If more than one laser line defines a particular plane, then the LOP for each of the lasers must lie in that plane before other alignment adjustments can be made effectively.

8.1.2 TILT THE LASER PLANE TO THE CORRECT ALIGNMENT

The tilt adjustment (Figure 4.2) for each laser allows the laser diode barrel to be tilted about the LOP. The LOP does not change position as a result of this adjustment. The requirements for this adjustment are slightly different for each plane in the system. Tilt adjustment cannot be made correctly until the LOP has been located accurately in the correct plane

8.1.2.1 Y PLANE

Lasers that form the Y plane (Figure 4.1) in the Maxx-1100 system (e.g., the fixed lasers in the Z actuators (Maxx-1100 unit#1, unit#2) and fixed laser in the X actuator (Maxx-1100 unit#3) must be tilted to be coplanar. This can be accomplished by using the tilt control on the fixed laser to move the laser line until it passes through the LOP of the laser on the opposite wall.

Note: If the rotation adjustment of the two opposing lasers is not correct, then the tilt adjustment described above may not be correct. Therefore, in the case of the Y plane, it may be more efficient to adjust rotation before tilt is adjusted.

8.1.2.2 X PLANE

The X plane (Figure 4.1) is a vertical plane. The moving laser on the ceiling mounted X actuator (Maxx-1100 unit#3) defines the X plane. The tilt control for this laser is used to adjust the X plane so that it is perfectly vertical (plumb).

Page | 27

8.1.2.3 Z PLANE

The Z plane (Figure 4.1) is a horizontal plane formed by two moving lasers (e.g., the moving lasers on the Z actuators (Maxx-1100 unit#1, unit#2) mounted on either side of the treatment room couch) must be in the same horizontal plane (i.e., level across the room). If the two opposing lasers have been correctly located with their LOP in the Z plane, then the tilt control can be used to move the projected laser line until it passes through the LOP of the opposing laser.

8.1.3 ROTATE THE LASER PLANE TO THE CORRECT ALIGNMENT

When the first two adjustments have been made correctly, rotation (Figure 4.2) of the laser plane should be the final required adjustment. This adjustment consists of rotating the laser line about its long axis.

In the case of the Y plane, laser alignment is most effectively accomplished if rotation adjustment of the fixed lasers precedes the tilt adjustment of these lasers. Again, the requirements for this adjustment are slightly different for each plane of the system, as described in the following sections.

8.1.3.1 Y PLANE

In the case of the two fixed lasers on either side of the couch (Z actuators Maxx-1100 unit#1, unit#2) that help define the Y plane (Figure 4.1), the laser lines must be rotated so that the lines are vertical (plumb).

In the case of the optional fixed laser(s) in the ceiling mounted X actuator (Maxx-1100 unit#3) that helps define the Y plane, the line must be rotated until it is parallel with the Y plane defined in the room.

8.1.3.2 X PLANE (Figure 4.1)

Rotation of the X line (generated by the moving laser in the ceiling mounted X actuator (Maxx-1100 unit#3)) allows it to be made perpendicular to the Y plane.

8.1.3.3 Z PLANE

The rotation adjustment for the two moving lasers (Maxx-1100 unit#1, unit#2) that define the Z plane (Figure 4.1) for the Maxx-1100 system allow these lines to be adjusted so that the line that is generated is horizontal (level) from end to end, parallel to the treatment couch.

Page | 28

8.2 SPECIFIC LASER ALIGNMENT PROCEDURES

Once power to the Maxx-1100 units has been established (see Section 7 for more details on system and power connections) and the moving lasers are positioned to the Laser Travel Zero position, final system alignment can take place as follows:

Step 1. Locate each moving laser or fixed laser in the system so that the LOP for each laser is accurately located in the correct plane.

Step 2. Use tilt and rotation controls to align laser lines so that the vertical and horizontal lines are aligned with their respective counterpart.

Step 3. Adjust the zero position of the moving laser on each actuator so that the laser corresponds with the isocenter and that the Maxx-1100 unit#1 and Maxx-1100 unit#2 are aligned at the same zero position.

8.2.1 LOCATING THE LOP FOR ALL MAXX-1100 SYSTEM LASERS IN THE CORRECT PLANE

The purpose of this task is to physically move the lasers so that the LOP of each laser is in the correct plane. Once the LOP of all the lasers are correctly positioned, the rotation and tilt of each fixed laser can be adjusted so that all the laser lines in the room fall within the correct plane.

Note: This task must be completed accurately; otherwise subsequent adjustment(s) cannot be made correctly. The procedures for this task vary depending on the equipment that is being used to align the Maxx-1100 system.

8.2.1.1 LOP LOCATION OF MAXX-1100 USING A ROTATING LASER

The primary purpose of the rotating laser in this procedure is to locate the fixed lasers and moving lasers in all units in the correct plane. (Figure 4.1)

8.2.1.1.1 Z PLANE

Is easiest done using a rotating laser, set up at the isocenter Z plane (horizontal orientation) on the treatment room couch. (Figure 4.1)

Position the Z actuators (Maxx-1100 unit#1, unit#2) laser line in the correct vertical position. The vertical position of the moving lasers must be adjusted so that the rotating laser passes through their LOP. After positioning use the remote control to set this as the new zero position. (When using the save feature all three Maxx-1100 units positions are updated.)

Page | 29

8.2.1.1.2 Y PLANE

A rotating laser can be used to locate the LOP for the fixed lasers that form the Y plane in the Maxx-1100 system. For a Maxx-1100 Unit#3, with no fixed laser, or with three Maxx-1100 units that includes the fixed laser. This is accomplished as follows:

Step 1. Set up the rotating laser at the isocenter in the Y plane. (Figure 4.1) Step 2. Reposition linearly (+/-10mm from its centre point) the fixed laser(s) until the

rotating laser passes directly through the LOP. Repeat for each fixed laser.

8.2.2 ALIGNING LASERS IN THE Y PLANE

Aligning lasers in the Y plane(Figure 4.1) is usually the most difficult part of Maxx-1100 system alignment because you must align all three fixed lasers in this plane (If Maxx-1100 unit#3 is equipped with a fixed laser). Again, this can only be accomplished successfully if the LOP for these three lasers has been located correctly in the Y plane, as described in the previous procedures (Section 8.2.1). Once this LOP is correct for all three lasers, use the tilt and rotation controls for the lasers for final alignment.

8.2.2.1 ALIGN THE FIXED LASER

Depending on the alignment tools that are being used, some of the steps outlined below may have been completed in previous procedures.

Step 1. Set up the rotating laser at the isocenter in the Y plane. (Figure 4.1) Step 2. Use the rotation controls on the fixed lasers of Maxx-1100 unit#1 and unit#2 to

make both project lines vertical. This can be done by making the lines parallel to the rotating laser line, or to the marks for the Y plane on the opposite wall, or using a plumb bob.

Step 3. Use the tilt control on the fixed lasers of Maxx-1100 unit#1 and unit#2 to move the line until it is directly on top the rotating laser line, or marks on the floor that identified the Y plane.

Step 4. Use a plumb bob to verify that the plane of the laser is vertical. If the plane is vertical and the plumb bob is held in the laser plane, the laser will simultaneously illuminate the entire length of the plumb bob string.

Step 5. If the laser line is not vertical, then the LOP of the fixed laser is not located in the same vertical plane as the isocenter, and corrective steps must be taken to locate the LOP of this laser correctly (Section 8.2.1).

Step 6. Use the rotation control on the Maxx-1100 unit#3 fixed laser to adjust the line until it is parallel with the two lines from unit#1 and unit#2.

Page | 30

Step 7. Use the tilt control on the Maxx-1100 unit#3 fixed laser to move the line until it is directly on top of the lines from unit#1 and unit#2 and the rotating laser line, or passes through marks on the floor that identified the Y plane.

At this point, all three fixed lasers that define the Y plane for the Maxx-1100 system should be coplanar. This can be confirmed with a piece of white paper, and verifying that when one laser is obstructed at any given time or position in the room, the position of the line on the paper does not change. If this is not the case, revisit the preceding alignment steps to determine which was not carried out correctly or with sufficient accuracy.

8.2.3 ALIGNING LASERS IN THE Z PLANE

Only two lasers are involved in aligning lasers in the Z plane (Figure 4.1); the process is thus simpler than that required for aligning lasers in the Y plane. The same principles do apply. Once the LOP for the two lasers involved is correct, then only rotation and tilt adjustments need to be made.

8.2.3.1 ALIGN THE MOVING LASERS

Correct laser alignment requires that the laser LOP is first correctly set. The ability to move the Z lasers on the Maxx-1100 will be used, some of the steps outlined below may have been completed in previous procedures.

Step 1. Set up rotating laser at the isocenter Z plane (horizontal orientation) on the treatment room couch. (Figure 4.1)

Step 2. Start with both moving lasers (Maxx-1100 Unit#1 and Unit#2) at the laser travel zero, move each laser until the rotating laser passes through their LOP. Use the remote control to set this as the new zero position. (When using the save feature all three Maxx-1100 units positions are updated.)

Step 3. Use the rotation control on the moving laser in the Maxx-1100 unit#1 to adjust the line parallel to the rotating laser line defining the Z plane, or so that it is parallel to the marks on the opposite wall.

Step 4. Use the tilt control on the moving laser in the Maxx-1100 unit#1 to move the line until it is directly on top the rotating laser line that defines the Z plane, or both marks on the opposite wall.

Step 5. Use the rotation control on the moving laser in the Maxx-1100 unit#2 to adjust the line parallel to the rotating laser line defining the Z plane, or so that it is parallel to the marks on the opposite wall.

Step 6. Use the tilt control on the moving laser in the Maxx-1100 unit#2 to move the line until it is directly on top the rotating laser line that defines the Z plane, or marks on the opposite wall and through the LOP of the Maxx-1100 unit#1 moving laser, and are coplanar with each.

Page | 31

At this point, the two moving lasers that define the Z plane for the Maxx-1100 system should be coplanar. If the two Z lasers are not co-planar at this point, you must determine which of the preceding alignment steps was not carried out correctly or carefully enough.

8.2.4 ALIGNING THE LASER IN THE X PLANE

There is only a single moving laser to align, the moving laser in the ceiling-mounted Maxx-1100 unit#3. This process is as follows:

Step 1. Set up rotating laser at the isocenter X plane defined by a line on the installation phantom that is marked perpendicular to the Y plane in the system. (Figure 4.1)

Step 2. Start with the moving laser (Maxx-1100 Unit#3) at the laser travel zero, move the laser’s LOP close to the centre of the treatment couch, and use the remote control to set this as the new zero position (When using the save feature all three Maxx-1100 units positions are updated. Make sure that Maxx-1100 unit#1 and unit#2 moving lasers have not been moved from the isocentre).

Step 3. Use the rotation control to rotate the laser until it is parallel to the X plane in the system.

Step 4. Use the tilt control on the Maxx-1100 unit#3 moving laser to adjust the laser until it is vertical. Use a rotating laser line, or a plumb bob to verify that the plane is vertical; the laser will simultaneously illuminate the entire length of the plumb bob string.

8.2.5 FINAL ALIGNMENT VERIFICATION

All lasers that define the X plane, Y plane, and Z plane for the Maxx-1100 system should be coplanar. This can be confirmed with a piece of white paper, and verifying that when one laser is obstructed at any given time or position in the room, the position of the line on the paper does not change. If this is not the case, revisit the preceding alignment steps to determine which was not carried out correctly or with sufficient accuracy.

SECTION 9: REMOTE CONTROL USER GUIDE

9.1 POWERING UP THE SYSTEM

Each Maxx-1100 has a detachable mains supply cord, replacement cords should have

A minimum 10 A Rating grounded 18AWG cord. The on switch is located near the entry point of this cord. Plug in unit with the switch in the off position then switch unit on.

The power input also contains a replaceable fuse which Cemar Electro recommends replacing with a rated 1.0A fuse.

The following instructions outline how to initialize power to the remote control.

9.1.1 CHARGING REMOTE CONTROL

The remote control is a battery-powered handheld electronic device. Before first time use, charge the remote as follows:

Step 1. Place the charging board on a flat, clean surface and plug it in to a power outlet. Step 2. Gently insert the remote control into the charging slot. The charging LED will

turn red. Step 3. Leave remote control in charger until the charging LED turns green. This may

take several hours. Once the LED is green, the remote control battery is fully charged. Note: The remote control uses a 3.6 Volt Lithium ion battery return damaged or no longer used Remotes to Cemar Electro for proper disposal.

Note: Whenever possible, rest the remote control on the charging board to ensure the battery is constantly charged.

9.1.2 POWERING UP REMOTE CONTROL

Power the remote control on by toggling down the switch at the bottom of the remote control. Allow approximately 10 seconds before the Start page appears on the screen.

Page | 33

9.1.3 LASER UNIT DISPLAYS

WARNING: Repeatedly turning on and off the laser units can cause damage to your laser units.

• Unit Number Display: This 8-segment LED displays the unit number, which should be 1, 2, or 3 for this revision. No two units can have the same unit number in a single room.

• System LED: The green LED indicates the system status of the unit. It is dark during calibration at power up and turns solid green when calibration is successfully completed. It blinks in different patterns indicating errors encountered during calibration or regular operation. Refer to Table 9-1 for details about System LED blinking.

• Ethernet LED: The amber LED indicates status of Ethernet connection between the unit and the router. Solid amber indicates the connection is correctly established. A dark LED indicates there is no valid Ethernet connection between the router and the unit. It starts blinking when Ethernet initialization and static IP address assignment cannot be completed.

• Zigbee LED: The red LED indicates status of Zigbee wireless connection between the unit and the remote control. Solid red indicates the connection is correctly established. A blinking LED means the connection cannot be established.

During power up, the following events should occur in order.

Step 1. Lighting Unit Number Display will become illuminated. Step 2. Establishing wireless connection: Zigbee LED starts blinking, indicating the unit

firmware is searching for a remote control with the same PAN ID. Zigbee LED turns solid red once it is connected to the remote control.

Step 3. Starting laser beams: Both the fixed and movable lasers start beaming. If laser beams cannot be started, the subsequent events will not occur.

Step 4. Establishing Ethernet connection: Ethernet LED is solid amber if the unit is connected to a router via Ethernet cable; otherwise, the Ethernet LED is off. If neither wireless connection nor Ethernet connection can be established, the subsequent events will not occur.

Figure 9-1. LED Display Panel on top of MAXX-1100 unit. These LEDs indicate status of

different modules of the unit.

Page | 34

Step 5. Encoder checking and calibration: The movable laser starts moving in the negative direction (i.e., moving further away from the fixed laser). It changes direction when it hits the stopper on the negative end. The movable laser will travel the length of the encoder rail and hits the stopper on the positive end, close to the fixed laser. If no error is detected during the process, System LED becomes solid green indicating the calibration was successful.

Step 6. Moving to CT zero: The movable laser keeps moving towards CT zero, if available. At initial power up, the laser will remain at the positive end as CT zero has not yet been established. Refer to Section 10.2.3.1 for instructions on how to set up CT Zero of MAXX-1100 system.

Step 7. Following successful completion of the above steps, the laser unit is ready to accept commands from desktop application via the Ethernet interface and/or from remote control via the Zigbee interface.

Table 9-1. Summary of LED blinking patterns during laser unit power up

Code Blinking LED Blinking Pattern (per second) Cause

Z0 Zigbee LED

Zigbee module in the laser unit cannot connect to remote control

E0 Ethernet LED

Fails to assign static IP address based on unit number

E1 System LED

9.2 REMOTE CONTROL OPERATION

The Start page (Figure 9-2) is the entry point to all the operations on the remote control.

9.2.1 PAN ID BOX

• Each remote control and all the laser units in the same room share a network ID. If

multiple rooms are equipped with MAXX-1100 units, each room has a unique network ID.

The network ID of each remote control is displayed at the bottom of the screen.

Figure 9-2. Start page.

Page | 36

• Depicts a PAN ID Box noting “PAN – 11”, which means this remote control has a network ID of 11.

• The PAN ID of remote control is configurable. Refer to Section 9.2.1 for more details.

9.2.2 LASER OPERATIONS ICON

The remote control must verify connection to a laser unit via Zigbee protocol before sending any commands. Refer to Section 9.3 1 to learn how to check wireless connection and to laser units and retrieve status data from connected units. Refer to Section 9.2 to learn how to use the remote control to perform various operations on connected units.

9.2.3 REMOTE CONTROL SETTINGS ICON

You may also check status and update important configurations of the remote control itself. Section 9.2 provides more details.

Status bar

Appears at the up right corner of the screen and indicates status of operation on the selected laser units.

The remote control and lasers are ready.

The latest laser operation is in process.

IMPORTANT: DO NOT touch the screen while the remote is in this state. If it lingers in this state much longer than the estimated time, restart the remote control.

The latest laser operation has succeeded.

The latest laser operation has failed. Refer to Section Error! Reference source not found. for troubleshooting instructions.

For all the operations, wait until the status bar turns from yellow to green or red before you click the next icon.

Note: It takes about one second for a single unit to process and reply to a non-laser-moving command. If a command is sent to all the connected units, it takes up to three seconds for the remote control to receive and process replies from all the units. For laser-moving commands, the responding time naturally depends on the distance that lasers have to travel.

9.3 LINKING AND STATUS CHECKING

The following details how to link units and check their status.

9.3.1 WIRELESS COMMUNICATION STATUS

There are three laser units in a fully equipped MAXX-1100 Laser System. The remote control checks laser units in the same network automatically every time when it enters the Connection page from the Start page. The Laser Status Checking page on the remote control will display as shown in Figure 9-3if any of the following cases applies:

Page | 38

• Remote control has just been powered up • PAN ID of the remote control has just been changed • Laser connection status has just changed (e.g. new units have joined network or

existing units have left network)

9.3.1.1 LASER STATUS INDICATORS

The most important information on Connection page are the Laser Status indicators. These indicators can display the following:

: This laser is connected.

: This laser is not connected.

Figure 9-4 shows all three MAXX-1100 laser units connected in the wireless network of remote control. If only Unit #3 is connected, the Laser Status Indicators will display as

. Laser operations will be available only on the Unit #3 laser.

If none of the lasers are connected, the Laser Status indicators will display as . No operation is available if none of the three lasers is connected.

9.3.1.2 CHECK STATUS ICON

Click Check Status icon to update status of laser units, including the current position, speed and power settings, and zero-point settings of every connected unit. This icon is always available regardless the status of wireless connections.

9.4 LASER UNIT STATUS

If at least one laser is connected, click Check Status icon to bring up the Laser Operation icons on the Laser Operation page, as shown in Figure 9-4.

Figure 9-3. Connection page; all lasers are connected.

9.4.2 LASER OPERATIONS ICONS

Click one of the following Laser Operation icons to open the corresponding laser operation page. Each icon is referenced to a section where group operations are detailed in full.

Home/CT Zero operations (Section 9.5)

Zero Point settings (Section9.5.4.1)

Laser Configuration(Section 9.6)

Laser Line Positioning (Section9.7)

Express Points operations (Section 9.8). These operations are only available when the current reference system is based on CT Zero (See details in Section 9.5).

You may refresh laser status at any time.

9.5 HOME/CT ZERO OPERATIONS

Figure 9-5 shows an example of CT Zero page of the remote control. This page shares many common elements with other position-related pages including Zero Settings page, Laser Position page, and Express Point page. These elements are explained in detail in this section.

Figure 9-5. CT Zero page: Reset zero.

Page | 41

9.5.1 CURRENT ZERO BOX

The Current Zero box displays the current setting of the reference system. Three possible reference systems are based on a zero-point setup:

• CT Zero: Zero point of MAXX-1100 system is aligned with CT machine zero. • PAT Zero: Zero point of MAXX-1100 system is set to be a temporary point other than

CT machine zero. • Reset Zero: Zero point of MAXX-1100 system is set to be reset zero, which is the

absolute zero point in the middle of the encoder rail.

A group of operations are dedicated to switching between different zero systems, as introduced in Section 9.5.4.

Current Zero box can also be found at the same location on Zero Settings page, Laser Position page, and Express Point page. Any zero setting change on one of these pages will update Current Zero box on all of these pages.

9.5.2 UNIT-AXIS SELECTION

Click the Unit-Axis Selection icon multiple times to work with all the connected units one by one. The same icon also appears on Zero Settings page and Laser Position page for unit-axis selection.

In a fully-installed MAXX-1100 system, there are three possible unit-axis selections.

1-Z1: the movable laser on Unit #1.

2-Z2: the movable laser on Unit #2.

3-X: the movable laser on Unit #3.

Click the Unit-axis Selection icon repeatedly to go through the above unit-axis selections sequentially. If one laser unit is not connected to the remote control, the corresponding unit-axis selection will be skipped.

9.5.3 CURRENT LASER POSITION

This text field shows the current position of selected unit-axis, relative to current zero setting. The following rules apply to all the laser position displays on the remote control.

All the position values are in unit of millimetre (mm).

A positive position value means the laser is closer to the fixed laser on the same unit compared to current zero point. A negative value means the laser is further away from the fixed laser compared to current zero point. A value of zero means the laser is right at current zero point.

The position text becomes >>>>>> while the lasers are moving.

Page | 42

9.5.4 LASER MOVING ICONS

These icons send commands to the selected laser only. Current Laser Position will be updated upon completion of any movements. The same group of icons also appear on the Zero Settings page.

Click the icon once to move the selected laser one step towards the negative direction.

Click the icon once to move the selected laser one step towards the positive direction.

Press and hold the icon to move the selected laser towards the negative direction; release the icon to stop the movement.

Press and hold the icon to move the selected laser towards the positive direction; release the icon to stop the movement.

Note: The remote control will ignore the command if the operator clicks the icons faster than twice per second. It takes about one second from sending a command to a unit to getting a positive reply from the unit, excluding time of laser movement. Clicking laser moving icons too fast does not speed up the process.

9.5.5 CT ZERO FUNCTION ICONS

Save CT Zero: Save current position as CT Zero point on all connected lasers.

Go Home: Move all connected lasers back to CT Zero point. This icon is hidden if CT Zero point is not set.

9.5.5.1 SET CT ZERO POINT

All MAXX-1100 units from Cemar Electro Inc. have been set to Reset Zero before shipping. At the first power-up after installation, the movable laser stops at the furthest positive end of the rail after calibration. The first step to complete immediately following mechanical installation is to set CT Zero on all the installed units.

On the remote control, Figure 9-6 shows the CT Zero page at the first power up. Current Zero box displays Reset Zero. Current Laser Position shows the position relative to the mechanical zero point. This value is the distance from the mechanical zero point to the stopper at the fixed laser side, where the movable laser is stopped after encoder calibration. This distance is slightly different on each unit.

Page | 43

The operations to set a new CT Zero point include two steps: Moving lasers to the desired coordinate and saving the coordinate as the new CT Zero.

Step 1. Align lasers to CT machine zero.

Select a unit-axis, and use the laser moving icons to align this laser to CT machine zero on the corresponding axis (Figure 9-6). Select next unit-axis and repeat until all the connected lasers are aligned to CT machine zero (Figure 9-7).

Step 2. Save current laser position as CT Zero.

Click the Save CT Zero icon to save the current coordinate as CT Zero point of the reference system (Figure 9-8). The Save CT Zero command is sent to all connected laser units (Figure 9-9). This command overwrites the existing CT Zero settings on laser unit firmware, if any.

Figure 10-8. CT Zero page: Figure 10-9. CT Zero page:

Saving new CT Zero. New CT Zero has been set.

Figure 9-6. CT Zero page: First power up. Figure 9-7. CT Zero page: Laser 1-Z1 is

aligned to CT Zero.

Page | 44

Upon successful completion the status bar will turn green. Current Laser Position becomes 0.0 mm for all connected lasers. The Current Zero box displays CT Zero. The previously hidden Go Home icon appears.

Now CT Zero has been set. CT Zero can be updated as many times as needed. The procedure is the same.

9.5.5.2 HOMING LASERS TO CT ZERO

At any point lasers need be returned to CT Zero point, simply open Laser Home page and click Go to Homeicon(Figures 9-10, 9-11). The Go to CT Zero command is sent to all connected lasers; each moveable laser will return to the saved CT Zero position and stop. The remote control updates Current Laser Position to be 0.0 mm for all lasers.

9.5.5.3 CHANGING ZERO SETTINGS

Laser reference system can be switched between CT Zero, Patient Zero, and Reset Zero.

Note: Remember that the MAXX-1100 system works in CT Zero reference system by default at power up, if CT Zero has been set. Any Patient Zero settings will be lost at power cycle. If you wish to keep certain coordination persistent after power cycle, use the Express Point settings (Section 9.8).

9.5.5.5 SWITCHING FROM CT ZERO TO PATIENT ZERO

The procedure to switch reference system from CT Zero to Patient Zero is similar to setting new CT Zero point.

Step 1. Move lasers to a designated coordination.

Select the laser axis with the Axis Selection icon. Move the selected laser to desired position with Laser Moving icons on this page or specifying target position on Laser Position page (Section 9.7). Repeat until all the lasers have moved to the future zero point.

In the example of Error! Reference source not found.Figure 9-13, the movable laser of Unit #1 is moved to -42.8 mm on the X axis in the CT Zero reference system. We assume that the movable lasers on the other two units have also been moved to the designated coordination.

Step 2. Save current laser position as PAT Zero point and switch reference system to PAT Zero.

Click the Switch to PAT Zero icon; the Switch to PAT Zero command is sent to all three units. Each unit updates their own zero settings and current laser position based on new zero point. Upon receiving positive replies from the units, the remote control updates related UI components on Zero Settings page: PAT Zero in Zero Settings box and 0.0 mm in Current Laser Position (Figure 9-14). The operator can click the Axis Selection icon to check position updates of other lasers.

From now on, all the position values are based on the saved PAT Zero point, until the operator switches the reference system to be based on another zero point.

9.5.5.6 SWITCHING FROM CT ZERO/PATIENT ZERO TO RESET ZERO

During installation or maintenance procedure, it may be necessary to move lasers to their Reset Zero positions. One click on Reset icon will drive all connected lasers to the middle point of their rails. The time duration for this operation depends on where the CT Zero is from Reset Zero.

When lasers are at CT Zero point (Figure 9-15), the operator will click the Reset Lasers icon, and the movable lasers start to move towards the mechanical zero point. Once the lasers arrive at the zero point, the units send replies to the remote control, which updates related UI elements on Zero Settings page (Figure 9-16).

At this time, the Zero Settings box will display Reset Zero; the current position is 0.0 mm relative to Reset Zero. The Reset Lasers and Switch to PAT Zero icons are hidden because these functions are not applicable when the reference system is based on Reset Zero.

Figure 9-15. Zero Settings page: CT Zero. Figure 9-16. Zero Settings page:

Lasers are at Reset Zero.

Page | 48

9.5.5.7 SWITCHING FROM PATIENT ZERO/RESET ZERO TO CT ZERO

To switch back to CT Zero reference system, click Switch to CT Zero icon and wait for the command to be completed.

When the movable lasers are at Reset Zero point and the reference system is based on Reset Zero point, the operator will click the Switch to CT Zero icon, and the remote control sends the Switch to CT Zero command to all lasers (Figure 9-17). The firmware on each unit switches the reference system to CT Zero, and calculates the current position relative to CT Zero. The remote control updates the UI upon receiving positive replies from the units. The updated position of movable laser will be displayed (Figure 9-18). The Reset Lasers and Switch to PAT Zero icons appear again because the lasers are in the CT Zero reference system, indicated in Zero Settings box.

Note: Lasers will not move during the switch from Patient Zero/Reset Zero to Ct Zero. Only the reference system is switched.

The operation is the same to change reference system from PAT Zero to CT Zero.

Typical usages of laser power functions are explained and illustrated below.

Adjust moving speed of movable lasers on all connected units.

With all the unit icons in selected mode, click Speed-up or Slow-down icon to change the moving speed. The Save Changes icon appears when there is any change. Then click Save Changes icon to send command to all connected units to actually change the speed settings on laser unit firmware. Any unsaved changes will be ignored.

In the example of Figure 9-27, the operator will click the Speed-up icon twice to change moving speed to Fastest. There is no color change in status bar because these changes are only on remote control side for now. The Speed-up icon is hidden because the tentative speed is already at the maximum value.

Similarly, Slow-down icon will be hidden if the current or tentative speed is at the minimum value. The operator will click the Save Changes icon to send commands to all the units to complete the operation. As shown in Figure 9-28 the movable lasers on all the units will move at the highest speed from now on.

Micro-stepping. These icons are not available for axis selection Z1 = Z2.

9.7.2 AXIS SELECTION ICON

Click the Axis Selection icon to select next available laser-axis in order to input target position value or use micro-stepping icons to adjust the final position of the selected laser-axis. There are four possible Axis Selection options: Z1=Z2, 1-Z1, 2-Z2, and 3-X. In most cases, Z1 and Z2 are both aligned to the Z axis of CT Zero. The operator can therefore specify one target position for both Z1 and Z2. However, it is also possible to specify different target positions for Z1 and Z2.

9.7.3 CURRENT LASER POSITION

The current position value is based on current zero setting, which is shown in the Zero Setting box on the Laser Home page. If Z1 and Z2 are not at the same position, the Current Position shows N/A when axis selection is Z1 = Z2. For all the other axis selections, the Current Position shows a valid position value or N/A if the remote control has no knowledge of valid position value of the selected laser-axis.

In the example of Error! Reference source not found.Figure 9-31, the movable laser of Unit #1 is at position 0.0mm (i.e., aligned with CT Zero).

Page | 56

9.7.4 USER INPUT ICONS

The operator can use the digits, negative sign, and dot icons on the remote control to enter a positive or negative value as the target position for selected laser.

Clear Input icon: This icon will clear all the input.

9.7.5 LASER POSITIONING

Typical usages of laser position functions are explained and illustrated below.

Move lasers to a target position.

Select a laser-axis, and provide a valid target position. Repeat this step until target positions are specified for all the available selections of laser-axis. Click Move Lasers icon to move all connected lasers. Wait until the remote control receives replies from all lasers.

In the example of Figure 9-32, Z1 and Z2 are initially at CT Zero point. The operator will enter the target position 79.5for the Z axis, as shown in Error! Reference source not found.Figure 9-33. The operator will click the Axis Selection icon twice, to check that target position for Z1 and Z2 are both 79.5. Clicking the Axis Selection icon again will select “3-X”, as shown in Error! Reference source not found. Figure 9-34.

Figure 9-32. Laser Position page: Figure 9-33. Laser Position page: Z1 = Z2 selected. Input for Z1 = Z2.

Page | 57

The operator will then click the Move Lasers icon to start moving the lasers. Figure 9-35 illustrates the Laser Position page while lasers are moving towards the target. The status bar will turn yellow; Current Position will appear as >>>>>> because the remote control has no knowledge of lasers’ current position while lasers are moving.

When lasers successfully arrive at their destinations, the status bar turns green. The current position is updated to the actual value; due to calibration, this may not be exactly the same value as the input number. The difference between the target position and the actual position is ± 0.2 mm, as shown in Figure 9-36 and Figure 9-37.

Invalid input for target position.

If the input value is not a valid target position, the input field will show tips on how to enter a valid target position value when the Move Lasers icon is clicked.

There are two types of invalidity: Input is in wrong format and input is out of range.

Figure 9-36. Laser Position page: Figure 9-37. Laser Position page: Z1 and Z2 at target position. 3-X at target position

Figure 9-34. Laser Position page: Figure 9-35. Laser Position page: Input for 3-X. All lasers moving to target.

Page | 58

Option 1. Input is in wrong format. The input value should be a valid positive or negative decimal number. Only one digit after the decimal point is permitted because the accuracy of laser positioning is 0.1 mm.

In the example of Figure 9-38, the operator entered an invalid target position then clicked the Move Lasers icon. The remote control checked the input string and detected the input was in the wrong format. The correct format will then display onscreen, as shown in Figure 9-39. The operator will need to click the Clear Input icon to clear the input box before entering the correct target position.

Option 2. Input is out of range.

The moving range of each laser is 600 mm. Depending on zero-point setup, input range is calculated and given as [-300 + zero offset, 300 + zero offset].

In the example of Figure 9-40, the operator entered a large number as the target position then clicked the Move Lasers icon. The remote control shows the current input range in the input box (Figure 9-41). The operator needs to click the Clear Input icon to clear the input box before entering the correct target position.

Page | 59

Adjust laser position in micro steps.

The micro-stepping icons can be used to adjust laser positions at high accuracy of less than 0.3 mm. Each micro-step is approximately 0.2 mm of distance.

Note: The first few steps after changing direction of movement may not result in any actual position updates because of motor backlash.

Save current position as an Express Point.

If it is necessary to move lasers to a certain position multiple times, the operator can save this position as an Express Point, allowing the lasers to move to this exact positioning the next time. Click the Go to Express Point icon to open Express Point page and follow instructions in the next section to set and visit Express Points.

9.8 EXPRESS POINTS OPERATIONS

An Express Point is a user-defined point that is saved in the system. System operators can move lasers to an Express Point on one-click operation, rather than adjusting lasers to specific positions every time. You may save up to five points in the current MAXX-1100 system. You may define or clear an Express Point at any time by visiting the Express Points page (Figure 9-42) from the Laser Functions page or the Laser Position page.

Note: All Express Point positions mentioned in this section are based on CT Zero, as the Express Points operations are only available when reference system is based on CT Zero.

9.8.3 EXPRESS POINTS MAIN OPERATIONS

Retrieving Express Points.

The remote control retrieves and displays Express Point information automatically when the operator has selected an Express Point.

The remote control will retrieve Express Point information from each connected laser unit, if it is the first time the Express Points page is loaded, or the operator has clicked

the Laser Status icon ( ) on the Laser Operations page (Figure 9-43). In these cases, the operator should expect a short delay when a defined Point is selected, while the remote control is loading data from laser firmware. Once the information is loaded, there should be no delay when switching between different points.

Setting up Express Points on all lasers.

Follow the three steps below to set up an Express Point. The operation is the same for both defining a new point and overwriting an existing point.

Step 1. Move lasers into the position to be saved as an Express Point.

Position the laser at the desired coordinates, following the positioning instructed detailed in Section 9.7.5.

Step 2. Select an Express Point.

Open the Express Points page, and use the Point Selection icon to select an Express Point.

In the example of Figure 9-44, Express Point P3 is selected. The current laser coordination is (Z1=50, Z2=50, X=-100).

Figure 9-43. P3 is selected.

Page | 62

Step 3. Save the position to the selected Express Point.

Click the Point Save icon to save the current position to the selected Express Point. The Save Point command is sent to all connected lasers. Lasers do not move upon receiving this command. Each laser saves the current position to the selected Express Point and replies to the remote control to confirm the result of this operation. The Point Position fields are updated accordingly if the remote control receives positive replies from all the connected lasers.

In the example of Figure 9-44, P3 is successfully defined. From now on, the lasers can move to P3 (Z1=50, Z2=50, X=-100) on one click.

Moving Lasers to Express Points.

The purpose of setting up an Express Point is to move lasers quickly to the position later. Follow these two steps to move laser to a defined Express Point.


Follow the same protocol as Setting up an Express Point (Section 9.8.3).

Step 2. Move all lasers to the selected Point.

Click Move Lasers to Point icon to send command Move Lasers to Point to all connected lasers. The lasers move to the selected Point and report the current position to remote control.

In the example of Figure 9-45, the lasers are at CT Zero point and P3 is selected as the target Express Point. In Figure 9-46, all lasers have moved to P3 at one click of Move Lasers to Point icon; positioning via this function is within ±0.2 mm of the target value. If the exact position is required, use the micro-stepping functions on Laser Position page to do fine adjustment.

Figure 9-44. Express Points page: P3 is saved.

Page | 63

Setting up Express Points on selected laser axis.

In case only one laser axis needs to be defined or modified for an Express Point, the operator can set up Express Point on the selected unit only.

Step 1. Move lasers into the position to be saved as an Express Point.

Please use laser positioning functions on other pages, such as the Laser Position page, to move laser to the desired position.

In the example of Figure 9-47, laser 3-X has been moved to position -50.0 mm.


Open the Express Points page, and use the Point Selection icons to select an Expression Point.

In Figure 9-48, Express Point P3 is selected. The existing position value of P3 for laser 3-X is -100.0 mm.

Step 3. Select a unit.

Click one of the Unit Number icons to select the laser unit and its movable laser.

Figure 9-45. P3 is selected as the Figure 9-46. Laser has moved to target point. P3.

Page | 64

Step 4. Save the position to the selected Express Point

Click Point Save icon to save the current position of the selected laser to the selected Express Point. The Save Point command is only sent to the selected laser, which saves the current position to the selected Express Point and sends reply to remote control indicating the result of operation. The Point Position field of the selected laser is updated accordingly if the remote control receives positive reply. No laser movement is triggered during this operation.

In the example of Figure 9-49, P3 has been updated on Laser 3-X from “-100.0” to “-50.0”.

Moving selected laser axis to Express Points

It is also possible to move only one laser axis to a saved position without affecting other lasers.


Step 2. Select a unit.

The first two steps of this operation are the same as Steps 2 and 3 of the previous operation.

Figure 9-47. Express Points page: Figure 9-48. Express Points page: Laser 3-X at new position. Laser 3 is selected.

Figure 9-49. Express Points page: P3 of Laser 3-X is updated.

Page | 65

Step 3. Move selected laser to selected Point.

Click Move Lasers to Point icon to send command Move Lasers to Point to the selected laser only. The laser moves to the selected point and reports its current position to the remote control. The other lasers are not affected.

In the example of Figure 9-50, the operator selects Express Point P2 on laser 3-X (i.e., the movable laser on Unit #3). The current position of laser 3-X is -50.0. The operator clicks the Move Lasers to Point icon and laser 3-X moves to its P2 position of 50.2. As shown in Figure 9-51, the updated position of laser 3-X is 50.3. Lasers Z1 and Z2 stay at the initial position.

Clearing an Express Point definition

A defined Express Point can be cleared. Please note that this operation is not available for individual laser.


Step 2. Clear the selected Point.

Click Point Clear icon to clear the definition of the selected Point.

In the example shown in Figure 9-52 and Figure 9-53, the definition of P3 has been cleared. No laser movement is triggered by this command.

control and allow users to resume previous operation.

9.10 NETWORK ID CONFIGURATION

This function allows operators to change PAN ID of the remote control.

Cemar Electro Inc. recommends permanently associating one remote control to one set of lasers. It may, however, be practical to use one remote control to adjust lasers in multiple rooms in such cases as:

• If a remote control is dysfunctional. Operators may temporarily use another remote control in place of the original to ensure uninterrupted medical service.

• Some operators prefer to use one remote control to set up and adjust laser units in all rooms to ensure better equipment management.

In any of the above cases, PAN ID of the remote control must be changed before it can be used to control lasers in the room. Please follow the steps below to switch PAN ID of a remote control.

Page | 70

9.10.1 PASSWORD INPUT

Click corresponding digit icons to input password. All the input digits will be displayed as * in the Password Input field.

Click the PAN ID Configuration icon on the Remote Control Settings page to open the Password page (Figure 9-57). The system will permit three chances to enter the correct password. After three unsuccessful trials, the remote control will disable this function and jump back to Remote Control Settings page (Figure 9-54) automatically.

Step 1. Enter password.

Note: Improper use of this function may cause communication chaos in multiple rooms equipped with MAXX-1100 laser units. This function is password-protected. Please contact Cemar Electro Inc. for more information.

9.11 TROUBLESHOOTING

If any operation cannot be completed successfully, the status bar on the remote control turns red after timeout. In most cases, this is due to wireless communication problem. Follow instructions in Section 9.3.1 to check if the target unit can be linked.

If linking to the unit is successful, try repeating the failed operation. In cases of continued failure, confirm the following:

Step 1. Make sure there is no other wireless device in the room. Step 2. Check the Zigbee LED on the target unit. If the LED is solid red, simply restart

the unit and try linking it again. If it is blinking, continue with Step 3. Step 3. Check the network status LED on other laser units in the same room. If all the

other units have their Zigbee LEDs solid, simply restart the unit and try linking it again. If it is blinking, continue with Step 4.

Step 4. Power down all the units and the remote control. Wait at least 10 seconds, then power up the remote control first, followed by the laser units. The Zigbee LEDs should turn solid shortly after power-up. Verify wireless connection to each laser unit.

Servicing and disposal:

Switch off Laser Unit and remove all power by disconnecting from the supply using the appliance inlet. Re-package and return to Cemar Electro for proper disposal or servicing.
