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. Unless the unit is specifically marked as a NEMA Type 3, 3R, 3S , 4, 4X, 6, or
6P enclosure, it is designed for indoor use only and it must not be installed
where exposed to rain and moisture.

4. Only use replacement parts recommended by Pelco.
5. After replacement/repair of this unit’s electrical components, conduct a resistance measurement between line and exposed parts to verify the exposed
parts have not been connected to line circuitry.
6. The installation method and materials should be capable of supporting four
times the weight of the enclosure, pan/tilt, camera and lens combination.
The product and/or manual may bear the following marks:
This symbol indicates that dangerous voltage constituting a
risk of electric shock is present within this unit.
This symbol indicates that there are important operating and
maintenance instructions in the literature accompanying this
unit.
CAUTION:
RISK OF
ELECTRIC SHOCK.
DO NOT OPEN.
TO REDUCE THE RISK OF ELECTRICAL SHOCK,
DO NOT REMOVE COVER. NO USER-
SERVICEABLE PARTS INSIDE. REFER SERVICING

2.0 DESCRIPTION
The PT175-24P is a light duty, indoor/outdoor pan and tilt unit capable of handling
enclosure, camera and lens combinations weighing up to 20 lb. The PT175-24P is
equipped with 24 VAC motors.
The PT180-24P and PT180-24SL are light duty, indoor pan/tilt units capable of
handling all enclosure, camera and lens combinations up to 20 lb (9.08 kg) in weight.
The PT180-24P and PT180-24SL are equipped with 24 VAC motors.
The PT180-24SL has the added feature of 360° pan rotation and both pan/tilts are
pre-wired for all control functions: pan/tilt, motorized z oom lens, camera power and
video. All connections are made at the input connector, eliminating the need for
wiring harnesses.
Pan/tilts in the PT270 Series are engineered to accommodate lightweight CCTV
cameras and are capable of handling enclosure, camera and lens combinations
weighing up to 15 lb (6.8 kg). The pan/tilts f eature long-lif e 24 VAC , 120 VAC or 230
VAC motors.
The pan/tilts of the PT280-24 Series are mini-size, light duty, indoor units capable
of supporting loads up to 15 lb (6.8 kg). They operate on 24 VAC.
They are factory pre-wired for pan and tilt control functions, motorized zoom lens
operation, camera power, and video. All connections are made at the input/output
connectors, eliminating the need for wiring harnesses. This greatly reduces installation time, while increasing reliability and serviceability.

PT175-24P Only
If your pan/tilt is installed in an inverted position, apply RTV silicone sealant to the
areas circled in Figure 1 after you reinstall the cover.
3.1 RESETTING POTENTIOMETERS
3.0 MAINTENANCE
IMPORTANT:
Be very careful
when resetting potentiometer
switches. Be sure that the pan/tilt
has been centered between maximum pan and tilt travel, regardless
of the adjustable limit stops. Failure to observe caution when resetting potentiometers could result in
damage to the preset positioning
ability of the pan/tilt.
WARNING:
NEVER
reposition the pan fixed
limit stop. Doing so
WILL DAMAGE the
wiring harness and, if
the pan/tilt has preset
positioning, COULD
cause the pan potentiometer to BREAK.
PT280-24P/PP and PT280-24SL/PP Models Only
Models with preset positioning (PP) use potentiometer switches that are factory set
to the full range of pan and tilt travel. Under normal operating conditions and at
routine service intervals they do not need adjusting.
Should your pan/tilt require any work on the drive mechanism other than routine
maintenance, perform the following procedure to reset the potentiometers.
To begin, remove the three screws on the front of the pan/tilt housing and lift the
cover to gain access to the pan and tilt motor assemblies.
1. Remove the potentiometer gears and position the pan/tilt to the middle of its
maximum pan and tilt travel, regardless of the position of the adjustable limit
stops. That is, the tilt table should be level and the fixed limit stop should be
opposite the limit switch.
2. Turn a potentiometer all the way in one direction until it stops, then observing
the number of turns, turn it back the other way until it stops. Rotate the potentiometer half the number of turns the other way to reach the center.
3. Replace the potentiometer gear.
4. Perform steps 2 and 3 f or the other potentiometer.

3.2 SERVICING DRIVE CHAIN ASSEMBLIES
Inspect the pan/tilt unit every six months to ensure trouble-free operation and an
extended product life. Harsh environments and/or continuous motion applications
may require more frequent maintenance.
Please read all of the instructions that follow before servicing the pan/tilt.
To begin, remove the three screws on the front of the pan/tilt housing and lift the
cover to gain access to the pan and tilt motor assemblies.
3.2.1 Tightening Drive Chains
Check the pan and tilt drive chains for tension. A mov ement of 1/32 of an inch to 3/32
of an inch in the chains is acceptable. If the mov ement of a chain e xceeds 3/32 of an
inch, adjust the chain as follows:
1. Loosen the screws securing the motor to the mounting frame.
2. Pry on the motor to apply tension to the chain. Do not over-tension the drive
chain.
3. Keep tension on the chain while tightening the screws.
3.2.2 Chain Drive Lubrication
Sprockets, chains, and gears should be well greased. If necessary, lubricate the
pan and tilt gears, sprockets, and chains as follows with a high-quality grease capable of withstanding temperatures from -50° to 170°F (-46° to 77°C). Do the fol-
lowing:
1. Liberally apply grease to the pan and tilt gears, chains, and sprock ets (refer to
Figure 2 or 3).
2. Operate the pan and tilt motors to spread the grease across the parts.
3. Apply additional grease if necessary.
4. Reinstall the cover. If the pan/tilt is installed outdoors in an inverted position,
apply RTV silicone sealant as shown in Figure 1.
