1.6 ELECTRICAL SAFETYThe PICO-GUARD Fibre Optic Safety System Controller(s) have been designed to meet with the Electrical Safety Standards as detailed in Block 3.1.4 on Page 11.

1.7 CONDITIONS OF EQUIPMENT USEThe Banner PICO-GUARD Fibre Optic Safety System Control-ler(s) are intended to be used in a variety of guarding applica-tions.

In addition to this Instruction Manual, refer to the associated documents listed below:

• PICO-GUARD Application and Design Guide(European version)

• PICO-GUARD Optical Element Data Sheets

• 3rd Party Documentation with respect to any external guard-ing device interfaced with the PICO-GUARD system.

The user must determine whether the use of a particular safe-guard or the PICO-GUARD Fibre Optic Safety System are per-mitted.

1.7.1 Appropriate ApplicationsThe Banner PICO-GUARD Fibre Optic Safety System Control-ler(s) are typically used in Access-Guarding, Perimeter-Guard-ing or Interlock Barrier Guarding applications for the following types of equipment:

• Assembly stations• Manufacturing cells• Automated production equipment• Robotic work cells

1.7.2 Non-Appropriate ApplicationsGenerally speaking, use of the Banner PICO-GUARD Fibre Optic Safety System Controller(s) are not permitted for the following types of equipment:

• Machinery that has inadequate or inconsistent machine re-sponse time and stopping performance

• Machinery with long or excessive stopping times without a guard-locking mechanism

• Guarding any machine that ejects materials or component parts in such a manner that the material or component parts are not contained and are considered to be a hazard

• Any environment that is likely to adversely affect photoelec-tric sensing system efficiency. For example, corrosive chem-icals or fluids or unusually severe levels of smoke or dust, if not controlled, may degrade the efficiency or effectiveness of the guarding function

The PICO-GUARD Controller and any electrically based de-vice(s) connected to the PICO-GUARD Controller must be mounted and used outside of the potentially explosive area or within appropriate explosion-proof enclosures.

1.8 SECURITY PROTOCOLCertain procedures for installing, maintaining and operating the PICO-GUARD Fibre Optic Safety System Controller(s) must be performed by either Designated Persons or Qualified Persons.

A Designated Person (see also page 69) is identified and des-ignated in writing, by the employer, as being appropriately trained and qualified to perform the specified checkout proce-dures on the PICO-GUARD Fibre Optic Safety System Control-ler(s). The Designated Person is empowered to:

• Perform manual Resets and hold possession of the Reset key, code or other security means, and

• Perform the Daily Checkout Procedure (see Block 6.1.3 on Page 33).

A Qualified Person (see also page 70) by possession of a rec-ognized degree or certificate of professional training, or by ex-tensive knowledge, training and experience, has successfully demonstrated the ability to solve problems relating to the instal-lation of the PICO-GUARD Fibre Optic Safety System Control-ler(s) and their integration with the guarded machine. In addition to everything for which the Designated Person is em-powered, the Qualified Person is empowered to:

• Install the PICO-GUARD Fibre Optic Safety System Control-ler(s)

• Perform all checkout procedures (see Block 6.1.3 on Page 33)

• Have access and make changes to the system configuration settings and

• Reset the system following a lockout condition.


Safety Information PICO-GUARD™ Fibre Optic Safety System Controllers

1.8.1 Manual ResetsSystem Resets are required in the following situations:

• After Manual Controller Power-Up operation• In Latch operation, after each optical channel latch condition

occurs• Lockout condition recovery, except USSI 1 input errors, after

a lockout cause has been correctedThe System Reset input is separate and operates independently from the USSI 1 Reset input.

USSI 1 Resets are required after a stop signal from the External Stop Device on USSI 1 input has been cleared (both USSI 1 channels closed/ON).

Manual Resets are performed using external Reset switches, System Reset and USSI 1 Reset. See Block 4.2.2 on Page 18 for Reset switch mounting and location requirements, and Block 4.8 on Page 24 for Reset procedures.

A Reset Switch could be a normally open (N.O.), momentarily held-closed push button, although some applications may re-quire a level of supervisory control. In this case, a key switch can be used where the key is secured and used by a Designated Person as specified in block 1.8 or Qualified Person as specified in Block 1.8 on Page 3 as appropriate.

Using a key switch provides some level of personnel or super-visory control, because the key may be removed from the switch. This delays a Reset while the key is under the control of an individual, but must not be relied upon solely to guard against accidental or unauthorized Reset. Spare keys in the pos-session of others, or additional personnel entering the guarded area unnoticed may create a hazardous situation.

1.9 CONTROL RELIABILITYIn addition to physical location requirements, safety standards require a safety system such as the PICO-GUARD Fibre Optic Safety System Controller(s) to fulfil some internal require-ments. For example, an optical safety system to be used in a Safety Category 4 application as per ISO 13849-1 (1999), must be third-party certified to the type 4 requirements of IEC 61496-1 (1997-08) and IEC 61496-2 (1997-11).

The PICO-GUARD Controller microprocessor-based circuitry features a diverse-redundant design. In addition, the PICO-GUARD Controller is extensively FMEA (Failure Mode and Ef-fects Analysis) (see FMEA on page 69) tested to establish an ex-tremely high probability that no system component will ever (even if it does fail) cause a failure to danger.

1.9.1 External Device Monitoring (EDM)Category 4 requires that a single failure does not prevent a nor-mal stop from occurring, or issues an immediate stop com-mand, and the next cycle is prevented from occurring until the fault is corrected.

A common method of satisfying these requirements is through the use of Dual-Channel control with monitoring, where a nor-mally closed, mechanically linked contact of each MPCE (or FSD-Final Switching Device) is wired as described in Block 4.1.4 on Page 17 and shown in Figure 33 thru’ to Figure 37.

2.4.1 PICO-GUARD ControllerThe Banner PICO-GUARD Controller is available in two different Models: type SCFDT-4A1 4-opto Channel Controller and type SCFDT-4A1C 4-opto Channel Controller with x4 auxiliary out-puts (Figure 4 on Page 7).

These Controllers feature several selectable functions: Manual or Auto Power-Up, Trip or Latch output, External Device Moni-toring (EDM), and Optical Channel controls.

In addition, the controller’s status indicators provide quick, clear, ongoing indication of system status and operation.

These controllers also have electrical Universal Safety Stop In-terface (USSI) inputs that can connect to other safeguards, E-stop devices, process controls or actuators. Regardless of the combination of optical elements and external safeguards used, when the system detects an interruption of an optical path or re-ceives a safety stop request, it provides a stop signal to the ma-chine control circuit. The machine control circuit then reacts to protect personnel from hazards, or to protect equipment, criti-cal tooling, or critical materials in process.

The controllers have two solid-state diverse-redundant safety outputs (OSSDs -Output Signal Switching Devices) to control 24 VDC loads. If an AC-powered MPCE or other load is required, an optional Interface Module or redundant positive-guided con-tactors may be used to convert the PICO-GUARD Controller outputs to isolated, mechanically linked relay contacts e.g., model IM-T-9A or IM-T-11A (not described in this Manual).

The OSSD (Output Signal Switching Device) safety outputs are capable of performing a handshake communication with the Muteable Safety Stop Interface (MSSI) or Universal Safety Stop Interface (USSI) found on other Banner Engineering safety products. The handshake protocol is satisfied by any Banner Engineering Safety Category 4 (per ISO 13849-1/EN954-1) device with OSSD outputs or MSSI/USSI inputs. This handshake verifies that the interface between the two devices is capable of detecting certain unsafe failures that may occur (such as a short circuit to a secondary source of power or to the other channel, high input resistance or loss of signal ground).

Removable terminals simplify the wiring process (for identifica-tion see Figure 5 on Page 7 and Figure 6 on Page 7). See also Block 4.4 on Page 20 for electrical connection instructions.

2.4.1.1 Auto/Manual Power-UpThe setting for Auto or Manual power-up determines whether the System requires a manual Reset to proceed to normal oper-ation when power is applied to the system.

2.4.1.2 Selectable Trip/Latch OutputThe setting for Trip or Latch output determines whether the System requires a Manual Reset to turn the OSSD outputs on after a blocked optical channel condition has occurred. If the system is set for Trip output, other measures must be taken to prevent a pass-through hazard.

2.4.1.3 External Device MonitoringThis feature allows the System to monitor the status of external devices, such as MPCEs. The choices are One- or Two-Channel Monitoring, or No Monitoring. External Device Monitoring (EDM) is used when the System OSSD outputs directly control the energizing and de-energizing of the MPCEs or other external devices.

2.4.1.4 Optical Channel ControlsThe PICO-GUARD Controller includes four separate optical sensing channels. Each of the four channels can monitor sever-al fibre optic safety interlock switches, beams or grids in the same fibre loop.

If required, each channel can monitor a separate zone or section of a machine (such as doors, entry gates, sensors, etc.).

DIP switches for each optical channel can be set for Enable or Disable for system operation in applications that require less than four operating optical channels.

☛ At least one channel must be set to ON.

2.4.1.5 Status IndicatorsStatus indicators on the front of the controller continuously show the status and operating conditions of the system. Indica-tors are provided for System Status, System Reset, each optical Channel, USSI 1 Reset, USSI 1 inputs, USSI 2 inputs, EDM in-puts, and OSSD 1 and OSSD 2 outputs. There is also a config-uration indicator to indicate a valid system configuration setting.

In addition to the controller status indicators, an optional re-mote display unit is available to provide the same ongoing sta-tus information at additional locations (see Accessories, Table 12 on Page 51).

2.4.2 Remote Display (optional)The Remote Display (type SFA-RD) provides an additional read-out of the PICO-GUARD Controller’s status and can be DIN-mountable.

2.4.3 Plastic Optical Fibre

Plastic optical fibre for use with Banner PICO-GUARD Fibre Op-tic Safety System Controller optical elements is available in bulk form (to be cut to length in the field) or pre-cut lengths with pol-ished ends for maximum Excess Gain.

Plastic fibres are available in three versions (Figure 8 on Page 8 refers):

Accessory sheathing is also available to provide additional pro-tection for any of these fibres. A fibre cutter (for bulk fibre) is shipped with each PICO-GUARD Controller.

For more information on plastic optical fibre such as type num-bers, order numbers etc., refer to Table 11 on Page 50.

2.5 NON-SAFETY APPLICATIONSThe PICO-GUARD Fibre Optic Safety System Controller(s) can provide highly reliable photoelectric sensing when used for equipment protection that does not impact personnel safety. Unlike standard limit switches, or photoelectric or inductive sensors, the PICO-GUARD Controller and optical elements are designed to default into a beam-break condition. With standard switches and sensors that can fail in an ON or GO condition, the loss of a stop signal could result in costly equipment damage.

The principle of a known or predictable failure mode (OFF or STOP) can be incorporated into a machine design to minimize situations that could result in damage to equipment. The ma-chine control can be designed to achieve a condition (e.g., a halt) that protects equipment if a stop signal is issued errone-ously or if the PICO-GUARD Fibre Optic Safety System Control-ler(s) fail.

Fibre Optic Equipment Protection is not intended for personnel safety. The user must ensure that the fibre optic assembly is ap-propriate for the intended application.

PICO-GUARD™ Fibre Optic Safety System Controllers Installation Information

4 INSTALLATION INFORMATION

Before installing the PICO-GUARD Fibre Optic Safety System Controller(s), read Block 1.7 on Page 3.

The PICO-GUARD Fibre Optic Safety System Controller’s ability to perform its safety guarding function depends upon the ap-propriateness of the application and upon its proper mechanical and electrical installation and interfacing to the guarded ma-chine. If all mounting, installation, interfacing, and checkout procedures are not followed properly, the System cannot pro-vide the protection for which it was designed. Installation must be performed by a Qualified Person as specified in Block 1.8 on Page 3. See also warning page 15.

4.1 ELECTRICAL REQUIREMENTS

4.1.1 External Stop Devices

The PICO-GUARD Controller provides two Universal Safety Stop Interface USSI inputs (see Block 5.2.1 on Page 28 for de-tailed USSI operation information):

• USSI 1 (Latch) — an Open/OFF input signal causes a Latch condition (Manual Reset required)

• USSI 2 (Trip) — an Open/OFF input signal causes a Trip con-dition (Auto Reset)

Both USSI inputs are designed to satisfy Functional Stop Cate-gory 0 (EN 418), where the opening of either of the two USSI input channels immediately removes electrical power from the machine control elements (see Figure 14 on Page 15 and Figure 15 on Page 15).

The inputs of each USSI (a/b and c/d) must meet a simultaneity requirement of 3.0 seconds upon closing and opening. A mis-match of more than 3.0 seconds results in a lockout. The USSI is a dual-channel input; an individual USSI can not be wired in a single-channel manner.

☛ Single-Channel connection is not possible. Both channels must be used together.

WARNINGS!BEFORE INSTALLING THE EQUIPMENT

READ THE SAFETY INFORMATION CONTAINED IN Chapter 1.

READ THIS CHAPTER CAREFULLY BEFORE INSTALLING THE SYSTEMTHE USER IS RESPONSIBLE FOR SATISFYING ALL LOCAL, STATE, AND NATIONAL LAWS, RULES, CODES, OR REGULATIONS RELATING TO THE INSTALLATION AND USE OF THIS CONTROL SYSTEM IN ANY PARTICULAR APPLICATION. EXTREME CARE SHOULD BE TAKEN TO MEET ALL LEGAL REQUIREMENTS AND FOLLOW ALL TECHNICAL INSTALLATION AND MAINTENANCE INSTRUCTIONS CONTAINED IN THIS MANUAL. THE USER HAS THE SOLE RESPONSIBILITY TO ENSURE THAT THE PICO-GUARD FIBRE OPTIC SAFETY SYSTEM CONTROLLER(S) ARE INSTALLED AND IN-TERFACED TO THE GUARDED MACHINE BY A Qualified Person as specified in Block 1.8 on Page 3 IN ACCORDANCE WITH THIS MANUAL AND APPLICABLE SAFETY REGULATIONS. READ Block 1.7 on Page 3 AND ALL OF Chapter 4 OF THIS MANUAL CAREFULLY BEFORE INSTALLING THE SYSTEM. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS BODILY INJURY OR DEATH.

!

WARNINGS!

INSTALLING MULTIPLE EXTERNAL STOP DEVICES WHENEVER TWO OR MORE EXTERNAL STOP DEVICES (CONTACT OUTPUT) ARE CONNECTED TO THE SAME USSI INPUT, CONTACTS OF EACH OUTPUT CHANNEL MUST BE CONNECTED TOGETHER IN SERIES. THIS SERIES COMBINATION IS THEN WIRED TO THE RESPECTIVE USSI INPUT (I.E., A TO B, AND C TO D). SEE THE PICO-GUARD APPLICATION AND DESIGN GUIDE (EUROPEAN VERSION) FOR FURTHER INFORMATION. NEVER CONNECT THE CONTACTS OF MULTIPLE EXTER-NAL STOP DEVICES IN PARALLEL TO THE PICO-GUARD USSI INPUTS. PARAL-LEL CONNECTION OF TWO OR MORE CONTACTS TO ONE USSI INPUT DEFEATS THE SWITCH CONTACT MONITORING ABILITY OF THE PICO-GUARD CONTROLLER AND CREATES AN UNSAFE CONDITION, WHICH COULD RESULT IN SERIOUS INJURY OR DEATH. WHEN TWO OR MORE EXTERNAL STOP DEVICES ARE USED, EACH DEVICE MUST BE INDIVIDUALLY ACTUATED (ENGAGED), THEN-REARMED. ALSO IF USING USSI 1 INPUT, THE PICO-GUARD CONTROLLER MUST BE RESET. THIS ALLOWS THE MONITORING CIRCUITS TO CHECK EACH SWITCH AND ITS WIRING TO DETECT FAULTS. FAILURE TO TEST EACH SWITCH INDIVIDUALLY IN THIS MANNER COULD RESULT IN UNDETECTED FAULT(S) AND CREATING UNSAFE CONDITIONS, WHICH COULD POSSIBLY CAUSE SERIOUS INJURY OR DEATH.

USSI RESPONSE TIME AFFECTS ON MINIMUM SAFETY DISTANCETHE UNIVERSAL SAFETY STOP INTERFACE (USSI) RESPONSE TIME MUST BE IN-CLUDED IN THE MINIMUM SAFETY DISTANCE CALCULATION OF THE EXTER-NAL STOP DEVICE BEING INSTALLED.FAILURE TO PROPERLY DETERMINE THE MINIMUM SAFETY DISTANCE COULD RESULT IN SERIOUS BODILY INJURY OR DEATH.

Installation Information PICO-GUARD™ Fibre Optic Safety System Controllers

Each Dual-Channel input is designed to monitor stop signals from various types of stop controls or devices, including:

• E-stop switches• Rope pull switches• Mechanical safety interlock switches• Safety outputs from safety light screens (contacts or Banner

handshake compatible solid-state safety outputs)• Safety outputs from safety modules (contacts or Banner

handshake compatible solid-state safety outputs)• Safety outputs from other PICO-GUARD controllers (Banner

handshake compatible solid-state safety outputs)If the PICO-GUARD Controller detects a failure of an external stop device output connected to the USSI inputs, both PICO-GUARD safety outputs (OSSD 1 and OSSD 2) are disabled (OFF) and the controller establishes a lockout condition (see Block 6.2.1.1 on Page 43 lockout condition recovery).

The USSI input response time (7 ms) must be included in the MINIMUM SAFETY DISTANCE calculation of the External Stop Device being installed.

Before connecting them to the USSI input terminals, the Exter-nal Stop Devices must be installed and the checkout procedures carried out in accordance with the manufacturer’s instructions, the PICO-GUARD Installation Manual and all applicable stand-ards.

If an External Stop Device is not used, Terminal a must be jump-ered to b, and Terminal c must be jumpered to d of the USSI In-put.

To use an External Stop Device, the factory-installed jumpers must be removed.

For External Stop Devices with contact outputs, the contacts must be redundant and capable of switching 15 VDC to 30 VDC @ 10 mA to 50 mA. Contacts must switch simultaneously (with-in 3 s of each other).

4.1.2 OSSD Outputs

Both OSSD (Output Signal Switching Device) outputs must be connected to the machine control so that the machine’s safety-related control system interrupts the circuit or power to the Ma-chine Primary Control Element(s) (MPCE), resulting in a non-hazardous condition. Final Switching Devices (FSDs) typically accomplish this when the OSSDs go to an OFF state.

Before making OSSD output connections and interfacing the PICO-GUARD Fibre Optic Safety System Controller(s) to the machine, reference should be made to the Output Specifica-tions as detailed in Table 2 on Page 12, the information outlined in Block 4.1.2 on Page 16 and wiring diagrams as shown in Figure 33 thru’ to Figure 37 as appropriate.

4.1.3 MPCE & FSD Interfacing ConnectionsEach of the two machine primary control elements (MPCE1 and MPCE2) must be capable of immediately stopping the danger-ous machine motion, irrespective of the state of the other. These two machine control channels need not be identical, but the stop time performance of the machine (Ts, used to calculate the MINIMUM SAFETY DISTANCE; see PICO-GUARD Applica-tion and Design Guide (European version) must take into ac-count the slower of the two channels. Some machines offer only one primary control element. For such machines, it is nec-essary to duplicate the circuit of the single MPCE to add a sec-ond. Refer to Figure 35 on Page 54 and Figure 36 on Page 55 or consult the machine manufacturer for additional information.

Final Switching Devices (FSDs) can take many forms, though the most common are force guided, mechanically linked relays or interface modules. The mechanical linkage between the con-tacts allows the device to be monitored by the external device monitoring (EDM) circuit for certain failures.

Depending on the application, the use of FSDs can facilitate controlling voltage and current that differs from the OSSD out-puts of the PICO-GUARD Controller. FSDs can also be used to control an additional number of hazards by creating multiple safety stop circuits.

WARNINGS!INTERFACING OF BOTH OSSDS

BOTH OF THE OSSD (OUTPUT SIGNAL SWITCHING DEVICE) OUTPUTS MUST BE CONNECTED TO THE MACHINE CONTROL SO THAT THE MACHINE’S SAFETY RELATED CONTROL SYSTEM INTERRUPTS THE CIRCUIT TO THE MACHINE PRIMARY CONTROL ELEMENT(S), RESULTING IN A NON-HAZARDOUS CONDITION. NEVER WIRE ANY INTERMEDIATE DEVICE(S) IN SUCH A MANNER THAT THE SAFETY FUNCTION CAN BE SUSPENDED, OVERRIDDEN, OR DEFEATED, UNLESS ACCOMPLISHED IN A MAN-NER AT THE SAME OR GREATER DEGREE OF SAFETY.

OSSD CONSIDERATIONS

TO ENSURE PROPER OPERATION, THE PICO-GUARD CONTROLLER OSSD OUT-PUT PARAMETERS AND MACHINE INPUT PARAMETERS MUST BE CONSIDERED

WHEN INTERFACING THE PICO-GUARD CONTROLLER SOLID-STATE OSSD OUT-PUTS TO MACHINE INPUTS (SEE Block 3.2.1 on Page 12). MACHINE CONTROL CIRCUITRY MUST BE DESIGNED SO THAT THE MAXIMUM LOAD RESISTANCE VALUE

IS NOT EXCEEDED AND SO THAT THE MAXIMUM SPECIFIED OSSD OFF-STATE VOLTAGE DOES NOT RESULT IN AN ON CONDITION. FAILURE TO PROPERLY INTER-FACE THE OSSD OUTPUTS TO THE GUARDED MACHINE COULD RESULT IN SERIOUS

BODILY INJURY OR DEATH.

!



4.1.3.1 Safety Stop CircuitsA safety stop allows for an orderly cessation of motion for guarding purposes, which results in a stopping of motion and removal of power from the MPCEs (assuming this does not cre-ate additional hazards). A safety stop circuit typically comprises a minimum of two normally open (N.O.) contacts from mechan-ically linked relays, which are monitored (through EDM) to de-tect certain failures in order to prevent the loss of the safety function. Such a circuit can be described as a safe switching point.Typically, safety stop circuits are either Single-Channel, which is a series connection of at least two N.O. contacts; or Dual-Channel, which is a separate connection of two N.O. con-tacts. In either method, the safety function relies on the use of redundant contacts to control a single hazard (if one contact fails ON, the second contact arrests the hazard and prevents the next cycle from occurring).

The interfacing of the safety stop circuits must be accomplished so that the safety function can not be suspended, overridden, or defeated, unless accomplished in a manner at the same or greater degree of safety as the machine’s safety related control system that includes the PICO-GUARD Controller. The N.O. safety outputs from an Interface Module provide a series con-nection of redundant contacts that form safety stop circuits for use in either Single-Channel or Dual-Channel control (refer to Figure 35 on Page 54 and Figure 36 on Page 55).

4.1.3.2 Dual-Channel ControlDual-Channel control provides the ability to electrically extend the safe switching point beyond the FSD contacts. With proper monitoring (i.e. EDM), this method of interfacing is capable of detecting certain failures in the control wiring between the safe-ty stop circuit and the MPCEs. These failures include a short-circuit of one channel to a secondary source of energy or volt-age, or the loss of the switching ability of one of the FSD out-puts. Such failures could lead to the loss of redundancy or to a complete loss of safety, if not detected and corrected.

The possibility of a failure to the wiring increases as the physical distance between the FSD safety stop circuits and the MPCEs increase, as the length or the routing of the interconnecting wires increases, or if the FSD safety stop circuits and the MPCEs are located in different enclosures. For this reason, Dual Channel control with EDM monitoring should be used in any in-stallation where the FSDs are located remotely from the MPCEs.

4.1.3.3 Single Channel ControlSingle-Channel control, as mentioned, uses a series connection of FSD contacts to form a safe switching point. After this point in the machine’s safety-related control system, failures can oc-cur that would result in the loss of the safety function (such as a short-circuit to a secondary source of energy or voltage).

For this reason, Single-Channel control interfacing should be used only in installations where FSD safety stop circuits and the MPCEs are mounted within the same control panel, adjacent to each other, and are directly connected to each other; or where the possibility of such a failure can be excluded. If this can not be achieved, then Dual-Channel control should be used.

Methods to exclude the possibility of these failures include, but are not limited to:

• Physically separating interconnecting control wires from each other and from secondary sources of power.

• Routing interconnecting control wires in separate conduit, runs, or channels.

• Locating all elements (modules, switches, and devices under control) within one control panel, adjacent to each other, and directly connected with short wires.

• Properly installing multi-conductor cabling and multiple wires through strain-relief fittings (Over-tightening of a strain-relief can cause short-circuits at that point).

• Using positive-opening or direct-drive components, installed and mounted in a positive mode.

4.1.4 EDM Inputs

Each of the two machine primary control elements (MPCE1 and MPCE2) must be capable of immediately stopping the danger-ous machine motion, irrespective of the state of the other. These two machine control channels need not be identical, but the stop time performance of the machine (Ts, used to calculate the MINIMUM SAFETY DISTANCE) must take into account the slower of the two channels. Some machines offer only one pri-mary control element. For such machines, it is necessary to du-plicate the circuit of the single MPCE to add a second. Refer to Figure 33 thru’ to Figure 37 or consult the machine manufactur-er for additional information.

WARNING!EXTERNAL DEVICE MONITORING (EDM)

IF THE SYSTEM IS CONFIGURED FOR NO MONITORING, IT IS THE USER’S RE-SPONSIBILITY TO ENSURE THAT THIS DOES NOT CREATE A HAZARDOUS SITUATION.

!



4.1.4.1 External Device MonitoringIt is strongly recommended that one normally closed, mechan-ically linked monitoring contact of each MPCE (or FSD) be con-nected to External Device Monitoring (EDM) inputs (see Figure 33 thru’ to Figure 37 as appropriate). If this is done, proper operation of the MPCEs is verified. Monitoring MPCE contacts is one method of maintaining control reliability.

EDM ConnectionPICO-GUARD Controller terminals 12 thru’ to 15 provide con-nection for the EDM inputs. EDM must be wired in one of the three following configurations and must agree with the control-ler’s EDM DIP switch settings (Block 4.7 on Page 23 refers). 1-Channel and 2-Channel EDM are used when the PICO-GUARD Controller OSSD outputs directly control the energizing and de-energizing of the guarded machine’s MPCEs.

1-Channel MonitoringThis is a series connection of closed monitor contacts that are mechanically linked mechanically linked from each device con-trolled by PICO-GUARD Controller. 1-Channel monitoring uses EDM 1 input only. EDM 2 input must be left open (no connec-tion). At power up, EDM 1 input shall be verified to be in the closed state.

When the OSSD outputs have changed from ON to OFF, EDM 1 input shall be verified to be in the closed state within 250 ms.

While the OSSD outputs remain OFF, EDM 1 input shall be pe-riodically verified to be closed.

When the OSSD outputs change from OFF to ON, EDM 1 input shall be verified to be open within 250 ms. Once EDM 1 input has been verified to be open, EDM 1 input shall be allowed to be either open or closed, for as long as the OSSD outputs remain ON.

For 1-channel EDM connection, Figure 36 on Page 55 should be referred to. The monitor contacts should be connected be-tween EDM 1 a and b (terminals 12 and 13) or between +24V dc and EDM 1 b (terminal 13). EDM 2 should be left open (termi-nals 14 and 15, no connection). The configuration DIP switches should be set to 1, (see Block 4.5.1 on Page 22).

2-Channel MonitoringThis is a separate connection of closed monitor contacts that are forced-guided (captive contact) from each device controlled by the PICO-GUARD Controller. The monitoring contacts should always close within 250 ms of the corresponding OSSD turning OFF; they stay closed for as long as the OSSD outputs are OFF. When the OSSD outputs are ON, both monitor contacts must be in the same state (either open or closed) within 250 ms of each other.

No MonitoringThis setting should be used initially, in order to perform the In-itial Checkout (Block 4.5 on Page 21). If No Monitoring is se-lected, the user must ensure that any single failure of the external devices does not result in a hazardous condition and, in such a case, that a successive machine cycle is prevented (see Block 1.9 on Page 4, Control Reliability).

4.2 CONTROLLER INSTALLATION

4.2.1 Mounting the Controller1) Mount PICO-GUARD Controller inside a lockable enclosure

with a minimum rating of IEC IP54. The control may be mounted onto a standard 35 mm DIN rail as shown or direct-ly to backplate of lockable enclosure, using supplied hard-ware.

4.2.2 Mounting Reset Switches

Reset switches are User supplied (see Figure 17 on Page 18). An optional SPST key Reset switch is available. See Table 10 on Page 49.

Figure 16 35 mm DIN Rail Attachment

WARNING!RESET SWITCH LOCATION

ALL RESET SWITCHES MUST BE:• OUTSIDE THE HAZARDOUS AREA, IN A LOCATION THAT ALLOWS THE

SWITCH OPERATOR FULL VIEW OF THE ENTIRE GUARDED AREA• OUT OF REACH FROM WITHIN THE GUARDED SPACE• PROTECTED AGAINST UNAUTHORIZED OR INADVERTENT OPERATION.

IF ANY AREAS WITHIN THE GUARDED AREA ARE NOT VISIBLE FROM THE RESET SWITCH, ADDITIONAL MEANS OF GUARDING MUST BE PROVIDED, AS DESCRIBED IN ISO/DIS 13855 (2002) SAFETY STANDARDS. FAILURE TO DO SO COULD RE-SULT IN SERIOUS INJURY OR DEATH.

!

Figure 17 Typical Reset Switch



All Reset switches must be mounted outside the guarded area, and out of reach from within the guarded area. The entire guard-ed area should be visible from the Reset switch location. If any areas are not visible, other means must be used to ensure that no personnel are within the guarded area when the system is Reset (see warning page 18).

Reset switches must be protected from accidental operations and, depending on the applicable standards, from unauthorized operation (e.g., through the use of a key, guards, or rings).

4.2.3 Mounting the Remote Display (option)An optional remote display is available (see Figure 18 on Page 19) for remote monitoring of the system’s status. Up to four remote display units may be connected to one controller. For more information see installation instructions included with the remote display.

4.3 FIBRE INSTALLATION

4.3.1 Cutting the Fibre☛ Use only the Banner fibre optic cable listed in Table 11 on

Page 50, or call Banner Corporate Office listed on page 71 to determine fibre suitability.

For best operation, minimize the fibre lengths, number of splices, number of tight bends and operating distance of the optical devices. Refer to PICO-GUARD Application & Design Guide (European version) for further information.

If using the unsheathed fibre, each fibre must be installed such that the black sleeve of the optical fibre is protected from nicks, cuts or crushing. Each fibre must be routed sep-arately.

If using PVC sheathed fibre, the sheathing must be removed without damaging the black sleeve of the fibre. A 3 mm wire stripper is recommended for this purpose.

Polished fibre lengths are available for maximum excess gain (see Block 6.4.1 on Page 50).

1) Remove 15 mm to 20 mm of PVC sheath from each end of fibre to allow proper insertion into optical elements and con-troller.

☛ When using the disposable Banner plastic fibre cutter type PFC-2 (Figure 19 on Page 19 refers), each cutting port can only be used once.

2) Cut fibre to measured finished lengths so that signal loss is minimized.

4.3.2 Connecting Fibre to PICO-GUARD ControllerTo connect fibres to PICO-GUARD Controller:

1) Slide cap back to open fibre port.

2) Push in prepared fibre until it bottoms.

3) Slide cap forward to close fibre port (see Figure 20 on Page 20).

4.3.3 Connecting Fibre to Safety Interlock SwitchRefer to PICO-GUARD Application & Design Guide (European version).

4.3.4 Routing Fibre Optic CableRefer to PICO-GUARD Application & Design Guide (European version).

4.3.5 Excess GainRefer to PICO-GUARD Application & Design Guide (European version).For troubleshooting weak signal (low excess gain) condition re-fer to Block 6.2.1.3 on Page 44.

4.4 ELECTRICAL CONNECTION

☛ PICO-GUARD wiring is low voltage; running these wires alongside power wires, motor/servo wires, or other high-voltage wiring can inject noise into the PICO-GUARD Sys-tem. It is good wiring practice (and may be required by code) to isolate PICO-GUARD System wires from high-volt-age wires.

For ease of wiring, the PICO-GUARD Controller has removable modular terminal blocks. These terminal blocks can accept in-dividual conductors from 0,2 mm2 to 2,5 mm2 or two stranded

conductors from 0,2 mm2 to 1,5 mm2. The wiring used should have an insulation temperature rating of at least 90° C.

Connect as follows:

1) Strip individual wire insulation approximately 6 mm.

2) Referring to Figure 21 on Page 20 or Figure 22 on Page 20 and Figure 33 thru’ to Figure 37 as appropriate, connect wiring to terminal blocks.

3) Torque each terminal screw to a recommended torque of between 0,57 Nm and 0,90 Nm.

5.2 NORMAL OPERATION

5.2.1 System Power-UpThe System powers up in one of two ways, depending on the Auto/Man configuration DIP switch settings (Block 4.7 on Page 23 refers).

If the controller is set for Auto Power-Up, it powers-up and Re-sets automatically.

If it is set for Manual Power-Up, a System Reset procedure is required after power-up (System Reset indicator double-flash-es) (see Table 6 on Page 30).

5.2.1.1 Auto Power-UpIf system is configured for Auto Power-Up, proceed as follows:

1) Switch ON power to PICO-GUARD Fibre Optic Safety System Controller(s).

System powers up and Resets automatically. No manual Reset is required.

When power is applied the following events occur:

• PICO-GUARD Controller self-tests to detect critical internal faults

• Configuration settings are checked• System is prepared for operationIf a critical fault is detected, the OSSD outputs remain OFF and diagnostic information is displayed via PICO-GUARD Control-ler’s status indicators.

If no faults are detected, Controller automatically begins normal operation. No System Reset procedure is required.

5.2.1.2 Manual Power-UpIf system is set for Manual Power-Up, a manual Reset proce-dure is required after power-up.

1) Switch ON power to PICO-GUARD Fibre Optic Safety System Controller(s).

When power is applied the following events occur:

• Controller self-tests to detect critical internal faults • Configuration settings are checked• System is prepared for operationIf a critical fault is detected, the OSSD outputs remain OFF and diagnostic information is displayed via the Controller’s Status Indicators.

If no faults are detected, Controller double-flashes System Re-set yellow to indicate it is ready and waiting for a System Reset.

2) When System Reset Indicator double flashes yellow, carry out Reset procedure as detailed in Block 4.8.1 on Page 24.

After a valid system Reset, system begins normal operation.

5.2.2 Running Procedures

5.2.2.1 Trip Output Configuration (Auto Reset)If any optical channel becomes blocked while system is running with Trip Output selected, the OSSD outputs turn OFF within 13 ms (the maximum optical channel response time). If all of the active (ON) optical channels then become closed (unblocked) and USSI 1 and USSI 2 are not in a Latch or Stop condition, the OSSD outputs come back ON.

No Resets of any kind are needed as all required machine con-trol Resets are provided by machine control circuit.

5.2.2.2 Latch Output Config. (Monitored Manual Reset)If any optical channel becomes blocked while System is running with Latch Output selected, the OSSD outputs turn OFF within 13 ms (maximum optical channel response time).

If all of the active (ON) optical channels then become un-blocked, Channel Status Indicators of channels that have not been blocked since the last Reset show green (disabled channel indicators OFF).

The indicators of the channels that have been blocked but are clear again should be double flashing and the System Reset in-dicator single flashes, indicating Controller is waiting for a Sys-tem Reset to clear the Latch condition.

When Latch is selected, the outputs come back ON only when all active channels are clear and after a System Reset. The Con-troller waits for a System Reset; when a valid system Reset sig-nal is received and all active channels remain unblocked and USSI 1 and USSI 2 are not in a Latch or Stop condition, the OSSD outputs switch ON.

5.2.2.3 USSI 1 OperationUSSI 1 input is used to connect various external devices or con-trols to provide a stop signal to the PICO-GUARD Fibre Optic Safety System Controller(s) (see Block 4.1.1 on Page 15). USSI 1 is used when a latching type of stop response is needed.

When a stop signal is received by the USSI 1 input, the PICO-GUARD Controller turns OFF the OSSD outputs within 7 ms (maximum USSI response time) and holds them OFF until USSI 1 stop signal has been removed (both USSI 1 input channels ON/CLOSED) and a valid USSI 1 Reset is received.

After a successful Reset of the USSI 1 latch condition, PICO-GUARD Controller resumes normal operation.

☛ If the OSSD outputs do not turn ON after a USSI 1 latch Re-set, check for a USSI 2 stop condition or for an optical chan-nel blocked or latch condition. The USSI 1 input must be jumpered if it is unused (see Block 4.1.1 on Page 15), and has no effect on operation of PICO-GUARD Fibre Optic Safe-ty System Controller(s).



5.2.2.4 USSI 2 OperationUSSI 2 input is used to connect various external devices or con-trols to provide a stop signal to the PICO-GUARD Fibre Optic Safety System Controller(s) (see Block 4.1.1 on Page 15). USSI 2 is used when a trip type of stop response is needed.

When a stop signal is received by the USSI 2 input, the PICO-GUARD Controller turns OFF OSSD outputs within 7 ms (maximum USSI response time). Once USSI 2 stop signal has been removed (both USSI 2 input channels ON/CLOSED), PICO-GUARD Controller resumes normal operation.

☛ If OSSD outputs do not turn ON after USSI 2 stop signal is cleared, check for a USSI stop or latch condition or for an optical channel blocked or latch condition. The USSI 2 input must be jumpered if it is unused (see Block 4.1.1 on Page 15) and has no effect on the operation of the PICO-GUARD Fibre Optic Safety System Controller.

5.2.2.5 System Lockout Conditions - Extern & Intern FaultsIf the PICO-GUARD Controller detects a critical fault, the OSSD, Aux and Weak outputs turn OFF, the Fault output turns ON and diagnostic information is displayed via the PICO-GUARD Con-troller’s status indicators (and the remote interface, if used). See Block 6.2.1.4 on Page 45 for details of error/fault condi-tions.

5.2.2.7 Non-Safety Outputs

Auxiliary OutputThe action of the Auxiliary output follows the action of the OSSD outputs. Refer to Table 8 on Page 32 for Auxiliary Output oper-ation. The Auxiliary output is a light-duty, 24 VDC, solid-state output used for control functions that are not safety related. A typical use is to communicate with a programmable electronic system (PES), such as a PLC. See Block 3.2.1 on Page 12 for output specifications.

Weak Signal Output The Weak Signal output is ON when one or more of the optical channels has a weak signal. See Table 8 on Page 32 for Auxilia-ry output operation and see Table 4 on Page 26 for Optical Channel Indicators. The Weak Signal output is a light-duty, 24 VDC, solid-state output used for non-safety-related monitoring of the optical channels. A typical use is to communicate with a programmable electronic system (PES), such as a PLC, that a low signal condition exists. See Table 2 on Page 12 for output specifications.

Fault OutputThe Fault output is ON when a Lockout condition exists due to an internal or external PICO-GUARD Fibre Optic Safety System Controller error or fault. See Table 8 on Page 32 for Auxiliary output operation and see Chapter 6 for resolution of error/fault conditions. The Fault output is a light-duty, 24 VDC, solid-state output used for system monitoring functions that are not safe-ty-related. A typical use is to communicate with a programma-ble electronic system (PES), such as a PLC, that a fault has been detected and a Lockout condition exists. See Block 3.2.1 on Page 12 for output specifications.

5.2.2.8 Reset ProcedureRefer to Block 4.8 on Page 24.

5.2.2.9 E-Stop ActivationIn the event of an E-stop (optional) fitted in the PICO-GUARD Fi-bre Optic Safety System being activated, the E-stop and the sys-tem must be Reset. To do this proceed as follows:

1) Reset Push Button by pulling up or back depending on orien-tation (Figure 27 on Page 32 refers).

2) Reset PICO-GUARD Fibre Optic Safety System as detailed in Block 4.8 on Page 24.

6.2 CORRECTIVE MAINTENANCE

6.2.1 Trouble Shooting

6.2.1.1 Lockout Conditions

A lockout condition causes all of the PICO-GUARD Controller OSSD outputs to turn or remain OFF, sending a stop signal to the guarded machine. The PICO-GUARD Controller provides di-agnostic information via the Status indicators or error codes via the RS-232 terminals of the Remote Interface (see Appendix A2 on Page 59) to assist in the identification of the cause(s) of lockouts.

To recover from a lockout condition (except USSI input errors):

1) Identify and correct all errors.

2) Perform System Reset as detailed in Block 4.8.1 on Page 24.

For USSI input errors, recover from a lockout condition as fol-lows:

3) Identify and correct cause of error (see Table 9 on Page 45).

4) Cycle External Stop Device connected to USSI input (closed/ON and then open/OFF). Both channels of External Stop Device must open (or go OFF) within 3 s of each other.

☛ For USSI errors, after lockout recovery, a USSI 1 Reset is re-quired when both channels go closed/ON.

A lockout condition is indicated by the System Status indicator Flashing red (All errors).

Table 9 on Page 45 provides information regarding error iden-tification, error description and appropriate action.

6.2.1.2 Electrical & Optical NoiseThe PICO-GUARD Fibre Optic Safety System Controller(s) are designed and manufactured to be highly resistant to electrical and optical noise and to operate reliably in industrial settings. However, serious electrical and/or optical noise may cause a random Trip or Latch condition. In very extreme electrical noise cases, a lockout is possible. In order to minimize the effects of transitory noise, the PICO-GUARD Fibre Optic Safety System Controller(s) respond to noise only if the noise is detected on multiple consecutive scans.

If random nuisance trips occur, check for the following:

• Loose or intermittent electrical wire or fibre optic connections• Optical interference from adjacent photoelectric devices• PICO-GUARD Controller input or output wiring routed too

close to high voltage wiring

Monitoring for Presence of NoiseThe PICO-GUARD Fibre Optic Safety System Controller(s), in many cases, indicates the presence of electrical or optical noise by flashing the appropriate PICO-GUARD Controller indicators with a flashing burst (three short consecutive flashes) .

As an example, if noise is detected on Channel 1, a flashing burst appears on the Channel 1 indicator.

Noise is indicated in a similar fashion for the other channel and input indicators (see Table 4 on Page 26).

In addition to PICO-GUARD Controller indicators, the RS-232 diagnostic data of the Remote Interface output can provide in-formation regarding noise detection (see Appendix A2 on Page 59). The noise path can be identified and the noise source can be found most quickly by monitoring the PICO-GUARD Controller indicators or the RS-232 diagnostic output.

ELECTRICAL CONNECTIONS OR REPAIRS SHOULD BE DONE ONLY BY A Qualified Person as specified in Block 1.8 on Page 3.

WARNINGS!POWER FAILURES AND LOCKOUTS

A LOCKOUT IS A DEFINITE INDICATION OF A PROBLEM AND SHOULD BE INVESTI-GATED AT ONCE, BY A Qualified Person as specified in Block 1.8 on Page 3. ATTEMPTS TO CONTINUE TO OPERATE MACHINERY BY BYPASSING THE PICO-GUARD FIBRE OPTIC SAFETY SYSTEM CONTROLLER(S) ARE DANGEROUS AND COULD RESULT IN SERIOUS BODILY INJURY OR DEATH.

Checking for Sources of Electrical NoiseAll PICO-GUARD Fibre Optic Safety System Controller wiring is low voltage. Running this wiring alongside power cables, mo-tor/servo wiring, or other high-voltage wiring, can induce noise into the PICO-GUARD Fibre Optic Safety System Controller(s). It is good wiring practice (and may be required by code) to iso-late PICO-GUARD Fibre Optic Safety System Controller(s) wir-ing from high-voltage cable and wiring.

The Banner Beam Tracker (type BT-1) is the recommended tool for detecting electrical noise. It can be used to detect electrical transient spikes and surges (Figure 32 on Page 44).

To use tool proceed as follows:

1) Cover lens of Beam Tracker with tape to block optical light from getting into Receiver lens.

2) Press RCV button on Beam Tracker and position it on wiring going to PICO-GUARD Controller or any other nearby wir-ing.

☛ Noise caused by switching of inductive loads should be ad-dressed by installing proper transient suppression across the load.

Checking for Sources of Optical Noise1) Remove power from PICO-GUARD Controller.

2) Completely block optical element emitting beam, or discon-nect emitting channel fibre at PICO-GUARD Controller.

3) Using Beam Tracker (type BT-1), check for light at optical element receiver by pressing RCV button on Beam Tracker and moving it near front of receiver’s sensing window.

4) If Beam Tracker indicator lights up, check for light from oth-er sources (other safety light screens, grids or points, or standard photoelectric sensors) by tracking down emitted light from them.

6.2.1.3 Low Excess Gain (Weak Signal Conditions)A low Excess Gain (Weak Signal) condition causes the optical channel status LEDs to flash and turns ON the Weak Signal out-put. To troubleshoot a weak signal or to maximize Excess Gain perform the following:

1) Check number and configuration of optical elements in opti-cal channel loop (see Chapter 4 of PICO-GUARD Applica-tions and Design Guide).

2) Inspect entire fibre run for:

• Cut or pinched fibre, also damage to jacket or sheathing (crushing or deformity).

• Tight bend radius (e.g. loops with tight bends). Bend ra-dius should be between 25 mm and 100 mm (see Chapter 3 of PICO-GUARD Applications and Design Guide).

• Extra splices and/or attenuators. 3) Verify optimum optical alignment and operating distances

between optical elements. Keep operating distance as short as possible (see PICO-GUARD Applications and Design Guide).

4) Check all fibre ends for clean, smooth cuts. Re-cut as nec-essary as detailed in Block 4.3.1 on Page 19. Replacing one or more bulk/cut fibre with polished fibres increases excess gain (type PW...P fibres – see Table 11 on Page 50).

5) Check for obstructions (e.g., loose o-rings, sheathing de-bris, etc.) within optical elements at all connections.

6) Ensure proper seating of fibre in each optical element.

7) Visually confirm light transmission at each switching point (emitter optical element). A red light should be present. If very dim, replace suspect element (emitter element, previ-ous receiver element or splice in a fibre loop) to see if prob-lem is resolved.

Ensure that environment does not negatively affect optical fibre or optical elements.

A2 REMOTE INTERFACEThe Remote Interface (terminals 28-31) provides for remote monitoring of the system status via the optional remote display (see Table 12 on Page 51 Accessories) or via a computer, PLC/PES or other monitoring device.The optional Remote Display provides the same status information as the PICO-GUARD Con-troller status indicators (Table 4 on Page 26 refers).

The RS-232 output of the remote interface provides continuous streaming, ASCII encoded hexadecimal data. Data packets in-clude 48 ASCII characters (46 data characters followed by a carriage return and line feed (see Figure 39 on Page 59).

The RS-232 output data protocol is:• 4800 baud rate• 8 data bits• No parity 8-N-1• 1 stop bit• No flow control

As an example, assume that data characters 39 and 40 are AS-CII C and 8, respectively. ASCII C is 12 in decimal or 1100 in bi-nary. ASCII 8 is 8 decimal or 1000 in binary. This means that the diagnostic byte for data packets 39 and 40 is 11001000. From this information, Table 15 on Page 63 tells us that:

Diagnostic Software (optional)A PC-compatible diagnostic software program is available on CD-ROM for the PICO-GUARD Fibre Optic Safety System Con-troller(s). This provides for easy viewing of system status and/or diagnosis of system error information when the PC is con-nected to the RS-232 terminals 30 and 31.

The CD opens with an Autorun screen that contains an installa-tion read-me file, followed by the installation of the software. See Figure 40 on Page 60 for sample screen.

When the isolated RS-232 output (terminals 30 and 31) is con-nected to a computer (Block 4.5.5.4 on Page 23 refers), PES or other monitoring device, the status and diagnostic information can be displayed (4800 baud rate) via the diagnostic software as shown in Table 14 on Page 60.

Glossary of TermsAttenuator Component used in an optical light circuit for reduc-ing Excess Gain.

Control Reliability A method of ensuring the performance in-tegrity of a control system. Control circuits are designed and constructed so that a single failure or fault within the system does not prevent the normal stopping action from being applied to the machine when required, or does not create unintended machine action, but does prevent initiation of successive ma-chine action until the failure is corrected.

Designated Person A person or persons identified and desig-nated in writing, by the employer, as being appropriately trained and qualified to perform a specified checkout procedure (see Designated Person as specified in block 1.8).

DIP (switch) Type of switch used for configuration settings.

E-stop Special switch push button positioned in strategic loca-tions and used for shutting off electrical power and motion in an emergency to the machine.

Excess Gain Term used in detecting sufficient light signal inten-sity in an optical fibre circuit. Can be construed as the amount of light that reaches the receiver which is in excess of the min-imum required to be detected for correct operation of the cir-cuit.

External Device Monitoring This feature allows the PICO-GUARD Controller to monitor the status of external devices, such as MPCEs.

Failure Mode and Effects Analysis (FMEA) A testing procedure by which potential failure modes in a system are analysed to de-termine their results or effects on the system. Component fail-ure modes that produce either no effect or a lockout condition are permitted; failures which cause an unsafe condition (a fail-ure to danger) are not. Banner PICO-GUARD Controller are ex-tensively FMEA tested.

Fibre Optic Interlocking Term used when optically linking sev-eral elements together to form a light operated safety circuit.

Final Switching Device (FSD) The component of the machine’s safety-related control system that interrupts the circuit to the machine primary control element (MPCE) when the output sig-nal switching device (OSSD) goes to the OFF-state.

Fixed Guarding/Hard Guarding Screens, bars, or other me-chanical barriers that prevent a person from entering or remain-ing in the hazard area undetected.

Key Reset A key-operated switch used to restore the FSDs and SSD to the ON state from a lockout condition. Also refers to the act of using the switch to Reset the PICO-GUARD Controller.

Latch Condition The response of the OSSD outputs (they turn OFF) when an object blocks/interrupts a light beam of the PICO-GUARD Controller operating in Latch mode. A manual Reset must be performed after all objects are removed (beam(s) clear) to Reset the output latch and allow the outputs to turn ON.



Lockout condition A condition of the PICO-GUARD Fibre Optic Safety System Controller that is automatically attained when the System detects internal or certain external errors. A lockout condition causes all of the PICO-GUARD Controller OSSD out-puts to turn or remain OFF, sending a stop signal to the guarded machine. To restore the PICO-GUARD Fibre Optic Safety Sys-tem Controller to Run mode, all errors must be corrected and a manual Reset must be performed.

Machine Primary Control Element (MPCE) An electrically pow-ered element, external to the PICO-GUARD Controller which di-rectly controls the machine’s normal operating motion in such a way that it is last (in time) to operate when motion is either initiated or arrested.

Machine Response Time The time between the interruption by the PICO-GUARD Controller OSSDs and the instant when the dangerous parts of the machine reach a safe state by being brought to rest.

MINIMUM SAFETY DISTANCE That distance, along the direc-tion of approach, between the outermost position at which the appropriate test piece is just detected and the nearest danger-ous machine part(s).

MPCE Monitor Contacts The normally closed contacts of a guarded machine’s MPCEs which are connected to the PICO-GUARD Controller EDM inputs. These contacts must be me-chanically linked to the control elements.

OFF State The state in which the output circuit is interrupted and does not permit the flow of current.

ON State The state in which the output circuit is complete and permits the flow of current.

Optical Channel Term used to describe the electronically con-trolled ports of the PICO-GUARD Controller that emit light beams via plastic fibre to the optical elements or other light op-erated safety devices.

Optical Element(s) Term used to describe the optical compo-nents used in the fibre optic light beam circuit (for example, fi-bre safety interlock switch, attenuator and splice) in conjunction with the PICO-GUARD Controller.

Output Signal Switching Device (OSSD) The component of the electro-sensitive protective equipment (ESPE) connected to the control system of the machine which, when the sensing device is actuated during normal operation, responds by going to the OFF-state.

Programmable Electronic System (PES) An integrated group of small, compact PLCs for utilization in a broad range of appli-cations (machine control, regulators, control devices, measur-ing and data acquisition etc.).

Point Of Operation The area of the guarded machine where a workpiece is positioned and a machine function (e.g., shearing, forming, punching, assembling, welding) is performed upon it.

Presence-Sensing-Device Initiation (PSDI) An application in which a presence-sensing device is used to actually start the cy-cle of a machine. In a typical situation, an operator manually po-sitions a part in the machine for the operation. When the operator moves out of the hazardous area, the presence-sens-ing device starts the machine (no start switch is used). The ma-chine cycle runs to completion, and the operator can then insert a new part and start another cycle. The presence-sensing device continually guards the machine. Single break mode is used when the part is automatically ejected after the machine opera-tion. Double break mode is used when the part is both inserted (to begin the operation) and removed (after the operation) by the operator. Banner PICO-GUARD Fibre Optic Safety System Controllers may not be used as PSDI devices on mechanical power presses.

Qualified Person A person or persons who, by possession of a recognized degree or certificate of professional training, or who, by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve problems relating to the subject matter and work (see Qualified Person as speci-fied in Block 1.8 on Page 3).

Remote Display Optional component used for remotely dis-playing a duplicate version of the information that is displayed on the PICO-GUARD Controller itself.

Reset The use of a manually operated switch to restore the OSSDs to the ON state from a lockout or a latch condition.

Response Time The time between the physical initiation of the safety device and the machine coming to a stop or the risk being removed.

Self Checking (circuitry) A circuit with the capability to elec-tronically verify that all of its own critical circuit components, along with their redundant backups, are operating properly. Banner PICO-GUARD Fibre Optic Safety System Controller(s) are self-checking.

Splice Component used in an optical light circuit for joining op-tical fibre.

Supplementary Guarding Additional electro-sensitive safety device(s), and/or hard guarding measures, used for the pur-pose of preventing a person from entering or remaining in the hazard area undetected.

Transitional Area Depending on alignment, fibre length, and other loss factors, the excess gain may fall below the threshold level before the switching distance and cause a weak signal or beam break condition before distance D. This region is called the Transitional Area.

Trip Condition In trip output models, the response of the FSD relays when an object equal to or greater than the diameter of the specified test piece enters the detection zone. In a trip con-dition, FSD1 and FSD2 simultaneously de-energise and open their contacts. A trip condition clears automatically when the object is removed from the detection zone. See also Latch Con-dition on page 69.
