1.0 GENERAL 1.1 IMPORTANT SAFEGUARDS AND WARNINGS Prior to installation and use of this product, the following WARNINGS should be observed. 1. Installation and servicing should only be done by qualified service personnel and conform to all local codes. 2. The weight of the camera/lens and enclosure shall not exceed 40 lb (18.14 kg) with 12VDC pan/tilts or 52 lb (23.59 kg) with 24 VAC or 120 VAC pan/tilts. 3. Only use replacement parts recommended by Pelco. 4.
2.0 DESCRIPTION The PT780 Legacy® Series pan/tilt units are designed for medium, indoor/outdoor use. Only Legacy Series enclosures can be mounted on the pan/tilt units. These enclosures are the EH4700L and EH5700L environmental enclosures and the EH8106L pressurized enclosure. Pelco’s RediLINKTM connector makes it simple and quick for you to install an enclosure. The weight of the enclosure with camera and lens must not exceed 40 pounds (18.14 kg) with the 12 VDC pan/tilt units or 52 pounds (23.
3.0 INSTALLATION 3.1 MOUNTING NOTE: To insure proper wiring and operation of your equipment, it is recommended that you test the pan/tilt unit and associated equipment in your facility before installing it in the field. Refer to Sections 3.2 through 3.4. Attach the pan/tilt unit to a wall or ceiling mount. Follow the instructions that are provided with the mount.
3.2 PAN AND TILT LIMIT STOP ADJUSTMENTS 1. 8 Remove the covers. a. Refer to Figure 1 and remove the Phillips screw on each side of the pan/ tilt unit. b. Refer to Figure 2 and place your hands under the cover halves. Exert a strong, upward force to release the covers from their internal latching devices. c. Refer to Figure 3 and pull the cover halves away from the pan/tilt unit. d. Set the covers down or hang them by the eyelets inside the covers (refer to Figure 4).
CAUTION: Never remove 2. the tilt limit stops. Adjust the tilt limit stops. Refer to Figure 5 for the location of the tilt limit stops. The tilt limit stop closest to the front of the pan/tilt unit limits the downward movement. The tilt limit stop closest to the back of the pan/tilt unit limits the upward movement. These movements are reversed if the pan/tilt unit is installed upside down. Loosen the screw in the limit stop that you want to adjust.
3.3 ENCLOSURE INSTALLATION Attach the camera enclosure to the pan/tilt unit. Follow the instructions that are provided with the enclosure. 3.4 ELECTRICAL INSTALLATION 3.4.1 LRD41 Series Legacy® Receiver/Drivers Connect the 37-pin round connector from the pan/tilt unit to the mating connector on the receiver/driver. 3.4.2 All Control Equipment Except LRD41 Series Legacy® Receiver/Drivers Make the interconnecting cable to link the 37-pin round connector from the pan/tilt unit to the control equipment.
Refer to Figure 9 and the following steps to construct the cable: WARNING: To prevent damage to the wiper, if your enclosure has one, AC high to turn on the wiper (pin 25 of the 37-pin connector) must come from the same circuit that provides power to the wiper (pin 15 of the 37pin connector). This is because the wiper and the on/off control share the same AC neutral (pin 16). See Figure 10. 1. Slide the unshielded and coaxial cables through the cable shell and rubber boot. 2.

NOTE: Relay boxes can not be used with 12 VDC pan/tilts.
Table D. Requirements to Wire Power to Camera Enclosure EH8106L: Power for the camera and heaters are separate. Refer to your camera manual for the camera wattage to determine the size of wire to use. Wire camera power through pins 9 and 14 of the 37-pin connector. The heaters use a total of 80 watts; wire through pins 15 and 16 of the 37-pin connector. EH4700L and EH5700L: To determine the wire gauge to use, add up the wattages for the different accessories inside your enclosure.

(Ten percent is generally the maximum allowable voltage drop for AC-powered devices.) EXAMPLE: An enclosure that re- Wire Gauge 20 NOTE: Distances are calculated Total vA consumed in feet; values in parentheses are meters.
4.0 OPERATION Refer to the manual for your control equipment for operating the pan/tilt unit. If your enclosure has the heater blanket option, it is thermostatically controlled to turn on at 40° F (4.44° C) and turn off at 60° F (15.56° C). The heater blanket allows operation of the pan/tilt unit to -50° F (-45.56° C).
5.0 MAINTENANCE If you need to remove the enclosure, protect the RediLINK™ connector area against moisture, dust, dirt, etc. Failure to do so could result in a bad connection. Also, damage to the pan/tilt unit or enclosure could occur when power is turned on. The following servicing should be done every six months with average use. 1. Remove the PT780’s outer casing. (Refer to step 1 under Section 3.2, PAN AND TILT STOP LIMIT ADJUSTMENTS.) 2.
c. (2) Using a screwdriver, pry the motor down at H to tighten for the correct chain tension. (You should not be able to freely move the motor with your finger, nor should it be so tight that it will not move at all as this usually leads to binding.) (3) Tighten the hex screws. Using a controller, you should now be able to move the PT780 without looseness or binding. If you have any problems, contact Pelco’s Technical Support Department. 5. Lubricate the chains.
