SAFETY PRECAUTIONS All persons installing and maintaining this equipment should be suitably qualified and work to national and local standards and codes of practice. This equipment is subject to remote control and may move at any time and should be installed such that it cannot come into contact with anyone. Persons working on the equipment should take appropriate precautions to ensure that unexpected movement does not occur as this could lead to injury. In situations where there could be a risk of injury, should any part of the assembly become detached for any reason and fall, normal common sense safety precautions should be employed. A strong safety chain between the housing and the mounting surface is recommended. The mounting surface must be sufficiently solid and strong to take the all-up weight of the complete configuration and take into account environmental aspects such as wind. Only the recommended bracket, column spacers and housings should be used. All cables should be of the correct type as specified by national and local standards and codes of practice and should be checked for wear at 6-monthly intervals and replaced if necessary. The installer should ensure that the unit is lightning protected where appropriate. Hazardous voltages are present in this equipment and may also be present within associated items affixed to it. As the mounting surface to which this head could be attached is user dependent, Molynx Videmech do not supply screws for securing the base of the unit to its mounting surface. It is the installers responsibility to ensure that fixing bolts are selected that are fit for purpose for the specific configuration required. All fastenings should be thoroughly checked for tightness one month after installation and, thereafter, at 6-monthly intervals.



PREVENTATIVE MAINTENANCE Due to the rugged construction of the 660 Series, no maintenance should be required. However, if the unit is exposed to very severe weather conditions or other harsh environments, the "O"-ring weather seals may need to be replaced about once every five years. All fastenings and cables should be thoroughly checked for tightness and wear every 6 months.

POINTS TO REMEMBER When installing the 660 Series head, there are some points to bear in mind: Check that the base mounting bolts do not extend through the base and scrape against the head, as this could damage to the pan motor or gearbox. Make sure that the head is disconnected from the controller when adjusting the limit settings for two reasons:- 1. to prevent the risk of electric shock, 2. to avoid unexpected movement of the head by the controller, which may injure the installer

adjusting the head. If the head is fitted with preset facility, take care that the pan axis limit settings are within the travel of the potentiometers, i.e.:- within ±165° of the factory set position. Ensure that the tilt axis limit stops are carefully adjusted so that the cable connector(s) are not damaged. Ensure that the load does not exceed 3.0 kg. Check the voltage rating of the unit and connect it to the correct supply. WARNING: This is a class A product. In a domestic environment, this product may cause radio interference in which case the user may be required to take adequate measures. This product is intended solely for use in general CCTV applications. The product must be installed and maintained in accordance with good installation practice to enable the product to function as intended and to prevent problems.

INSTALLATION INSTRUCTIONS LOCATING THE UNIT The 660 Series head has 3-hole fixing base and can be mounted on the BP04 wall bracket. A BAP66 adapter plate is available which converts the unit to 4-hole fixing enabling the unit to be mounted on a BP20 wall bracket or with BCS06, BCS09 & BCS12 column spacers. As a complete unit can weigh around 5 kg fully loaded, and taking adverse weather conditions into consideration, careful thought should be made as to the location of the unit:- Ensure the surface to which the unit is being mounted is solid and that there is no risk of crumbling brick or mortar. Take the size of the intended camera housing into consideration when deciding the location of the unit. Take care that the swing of the housing is not obstructed in any way before the limit stops are reached, as this will eventually cause damage to the motors or gearboxes.



WALL MOUNTING USING THE BP04 WALL BRACKET Once a suitable location for the mounting has been chosen, the following steps should be taken:- Drill three holes corresponding to the holes in the bracket shown in Figure 1, Three heavy-duty screws are recommended for securing the BP04 bracket to an exterior wall. Ensure that the bracket is firmly secured to the wall using the correct rawlplugs. If the head is equipped with preset facility, the relevant section on page 7 (Mounting the P66-P/D12 and P66-P/D Heads) should be read before the head is finally screwed to the bracket. Bolt the head to the bracket using the three M6 screws and washers supplied by screwing them into the base of the unit through the bracket from beneath as shown in Figure 2. Tighten them firmly using a 5 mm Allen key, making sure they do not extend through and actually touch the metal casting of the head.

MOUNTING THE UNIT USING COLUMN SPACERS BCS06, BCS09 & WCS12 The BCS06, BCS09 & BCS12 column spacers can be used to mount the head in conjunction with larger wall brackets (e.g. BP20), or alone to raise the head from a level surface. A BAP66 mounting adapter plate is required which bolts to the base of the unit. This has four holes in it to take M6 screws on a 101.6 mm (4") diameter as required by the column spacers and the BP20 bracket. The unit should be attached by screwing through the column spacer into the adapter plate using suitable M6 nuts and bolts (not supplied). If the column spacer is to be fitted to a wall bracket, four M6 nuts and bolts (not supplied) should be used. If the column spacer is to be mounted onto brickwork, heavy-duty screws are recommended.



SETTING THE 660 SERIES LIMITS

ADJUSTING THE PAN LIMITS The pan limit strikers can be found on the base plate ring of the unit as shown in Figure 3. They set the limits of rotation when the microswitch actuator pin on the underside of the head reaches one of them.

Figure 3 The pan limit strikers on the 660

Series head

They can be set as follows: Note: The pan limit settings should be adjusted once the unit has been mounted to prevent the limit stops becoming detached from the ring. Loosen the grub screws on each of the stops using a 1.5mm Allen key. Slide each stop on the base ring to its maximum pan left or pan right position. Tighten the grub screws up firmly. ADJUSTING THE TILT LIMITS

Figure 4 The tilt limit strikers on the 660 Series

head

Figure 4 shows the tilt limit strikers which can be set in the following way: Remove the screw-on cap from the tilt axis on the left side (when viewed from the rear) of the unit. The required tilt up and down limits can be set by repositioning the screws in the holes provided. Ensure that the screws are fully screwed in so that they reach the microswitch actuator pin. Note: Always make sure that the limit screws are positioned either side of the microswitch actuator pin.



VARIANTS OF THE 660 SERIES

THE P66-P/D12 & P66-P/D UNITS WITH PRESETS The preset facility is found on units type P66-P/D12 & P66-P/D, and consists of a potentiometer on each of the pan and tilt axes. These give highly accurate feedback of the position of each axis to a preset controller. The head is delivered with both pots in the centre of their tracks, i.e.:- they will deliver a voltage half of that supplied to them. The electrical rotation of the pots is ±165° from this factory set position, which is more than adequate for tilt angles, but may cause a restriction for the pan angle.

MOUNTING THE P66-P/D12 & P66-P/D HEADS The P66-P/D12 & P66-P/D preset heads can be mounted in the following way : Loosely screw the unit onto its intended-mounting surface such as a wall bracket or column spacer using the screws and washers supplied. Swivel the head by hand so that the camera is pointing towards the centre of its intended viewing arc. Tighten the three securing bolts in the base firmly using a 5 mm Allen key. Note: Preset may not function correctly if the limits on each axis are set to a viewing angle greater than ±165° from the factory set position, as the wiper on the potentiometer will travel past the end of its track.

CONNECTIONS TO THE 660 SERIES NON-PRESET HEADS (P66/D12 & P66/D) The 660 Series non-preset pan and tilt heads have a seven pin connector at the back of the head to which the signals that control the head are connected. A mating cable connector is supplied. This can be assembled by following the diagram on the packet. 16/0.2 cable for pan and tilt drive is recommended if possible. Care should be taken that the cable connector is properly made off, as moisture can be drawn into the head through the pins on the connector. This can be done using a heat-shrink sleeve. The P66/D12 & P66/D heads are controlled using only three of the pins on the 7-pin connector. Connections are shown in Table II: Figure 5 on page 8 shows the associated circuits for these signals.

Table II Control connections to 7-pin connector



Figure 5 Pin layout & possible control wiring for P66/D12 and P66/D non-preset heads

The direction of pan or tilt depends on the polarity of the applied voltage. Figure 5 shows how this can be achieved by connecting one terminal of a motor to ±12V and the other terminal of each motor is made common to 0V.



CONNECTIONS TO THE 660 SERIES PRESET HEADS (P66-P/D12 & P66-P/D) The 660 Series preset pan & tilt heads have a 10-pin connector at the back of the head to which the signals that control the head can be connected. The preset head also has both of the preset potentiometers wired through this connector. For this reason it is important that the connector is wired up correctly. A mating cable connector is supplied. Care should be taken that the connector is properly made off, as moisture can be drawn into the head through the pins on the connector. The P66-P/D12 & P66-P/D heads are controlled using 4 pins of the 10-way connector, 4 of the remaining pins are used for preset connections. Connections are shown in table III.
