2.0 DESCRIPTION
The PT780-24P/PPPSA and PT78024SL/PPSA pan/tilt units are designed for me-
dium-duty, indoor/outdoor use.
The PT780-24P/PPPSA pan/tilt is designed for use with the EH4718L/WPSA and
EH4718L/PSA environmental enclosures.
The PT780-24SL/PPSA pan/tilt is designed for use with the EH4718LDB/WPSA

3.0 INSTALLATION
3.1 MOUNTING
Attach the pan/tilt unit to a wall or ceiling mount. Follow the instructions that are
provided with the mount. Make sure the mounting surface and the selected mount
can support four times the combined weight of the pan/tilt unit and the camera
enclosure (including the camera and lens). The pan/tilt unit weighs approximately
21.5 pounds (9.68 kg). Refer to the manuals for your enclosure, camera, and lens
for the weights of those items.
NOTE: To insure proper wiring and
operation of your equipment, it is rec-
ommended 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.
Proceed to Section 3.2, ENCLOSURE INSTALLATION.
CAUTION: The PT780
pan/tilt units are designed
for upright or inverted (base
up) operation. Never mount
the pan/tilt horizontally.
NOTE: If you mount your pan/tilt unit
in the inverted position, you must in-
stall a rain cover (part number
90010019).
3.2 ENCLOSURE INSTALLATION
Attach the camera enclosure to the pan/tilt unit. Follow the instructions that are
provided with the enclosure.
Proceed to Section 3.3, ELECTRICAL INSTALLATION.
3.3 ELECTRICAL INSTALLATION
3.3.1 LRD41A11-X Legacy Receiver/Drivers
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 37-pin
connector). This is because
the wiper and the on/off con-
trol share the same AC neu-
tral (pin 16). See Figure 2.
Connect the 37-pin round connector from the pan/tilt unit to the mating connector
on the receiver/driver.

3.3.2 All Control Equipment Except
LRD41A11-X Legacy Receiver/Drivers
Make the interconnecting cable to link the 37-pin round connector from the pan/tilt
unit to the control equipment.
For cable requirements, refer to the following tables:
Table A:
Connector Pin Designations
Tables B and C:
Requirements to Wire Power to Pan and Tilt Motors
To determine the size of wire to use for enclosure power (pins 15 and 16), add
together the wattage of the camera and the wattage of the window wiper (if the
enclosure has a wiper). The wattage of the wiper is 25 watts.
If the pan/tilt has the optional heater blanket, the heater blanket requires 40 watts of
power (pins 31 and 32).
The following are some recommended common installation practices:
•
For unshielded conductors, use jacketed, stranded, multiconductor cable, with
additional conductors than needed for future servicing and/or additions. Use
color-coded conductors for ease of wiring and to identify functions at a later
date.
•
Keep a wiring diagram with the system for later reference.
Refer to Figure 1 and the following steps to construct the end of the cable that
connects to the pan/tilt unit:
1. Slide the unshielded and coaxial cables through the cable shell and rubber
boot.
2. Strip one inch of the jacket from the cables.
3. For the unshielded conductors, strip 1/8 inch of insulation from the individual
wires.
4. For the coax, unwrap the braid and twist it into a single conductor. Strip 1/8
inch of insulation from the center conductor. If you are using two coax cables
- one for video output and one for camera synchronization - twist the braid
from the two coax cables together.
5. Insert the end of each wire into a socket and crimp the end of the socket over
the wire’s insulation. This provides strain relief for the bare wire. Then crimp or
solder the bare wire to the socket.
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 37-
pin connector). This is be-
cause the wiper and the on/
off control share the same
AC neutral (pin 16). See Fig-
ure 2.
6. Refer to Table A and push each socket into the proper hole of the 37-pin con-
nector until it snaps into place. Once a socket snaps into place, it can not be
removed without a special AMP tool.
7. Slide the cable shell down the cabling and screw it to the 37-pin connector.
8. Screw the cable clamp to the cable shell.
9. Connect the 37-pin connector to the mating connector on the pan/tilt unit.
10. To make a watertight assembly, use RTV silicone (such as Bostik #9732 or
equivalent) on both sides of the connector to fill any gaps between the cable
clamp, shell, and cable.
Proceed to Section 3.4, PAN AND TILT LIMIT STOP ADJUSTMENTS.

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 3.4, PAN
AND TILT STOP LIMIT ADJUSTMENTS.)
2. Inspect the gaskets around the cover, tilt shaft, and spindle for damage.
3. Refer to Figure 13. It shows the parts locations of the tilt assembly. Look for
similar orientations of parts when adjusting the pan assembly.
4. Check the backlash adjustment.
Backlash is the slack or binding in a pan and tilt base mount. Determine back-
lash by lifting the mount assembly, grasping the base, and wiggling it. There
should not be any play or binding between the gear (A) and worm drive (B).
Play or binding indicates a backlash problem.
•
•
One backlash problem involves a worm and worm gear connection loose
enough to cause slipping or tight enough to cause binding.
The second involves a too-loose or too-tight chain, usually causing symptoms
similar to the worm and worm gear problem—slipping or binding.
a. Verify that the worm drive (B) is fully seated in the worm gear (A). If it is not:
H
G
(1) Locate the worm-driven gear for either the pan or the tilt motor linkage.
Loosen the three hex screws (F) holding the worm in place, but leave
enough thread in place to hold the assembly on the mount.
(2) Using your thumbs, gently move the worm forward or pull the assembly
back from the worm gear to either tighten or loosen the gear spacing to
the worm gear. Move the base of the pan and tilt to check the adjust-
ment.
Figure 13. Pan/Tilt Adjustments
(3) If you get movement in the base, press a finger down in the middle of the
worm assembly. If you get no movement in the base, use your thumb
and forefinger to pull the worm assembly back until you get movement.
(4) When the spacing is correct, tighten the hex screws. Start with the middle
screw to ensure proper spacing.
(5) Remove the screw (C) in the gear train nut (D).
(6) Tighten the gear train nut to remove any play.
Pelco Manual C342M-PSA (11/98)
17
Download from Www.Somanuals.com. All Manuals Search And Download.
(7) Line up the hole in the gear train nut with the nearest hole in the gear
train bracket (E).
(8) Replace the screw.
b. Refer to Figure 13. Adjust chain tension, if needed:
(1) Locate the pan or tilt motor on the assembly. Loosen the hex screws (G)
that hold the motor to its mounting bracket. Depending on which motor
assembly you are adjusting, there will be either three (pan) or four (tilt).
(Only two screws are shown in Figure 13.)
(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.
c. Using a controller, you should now be able to move the PT780 without loose-
ness or binding. If you have any problems, contact Pelco’s Technical Support
Department.
5. Lubricate the chains. Use a Teflon chain lubricant, such as TriFlon™.
6. Replace the covers. (Refer to step 2 under Section 3.5, FINAL INSTALLA-
TION.) When you reinstall the covers, apply new silicone sealant as shown in
Figures 9 and 12.
