Pelco Manual C325SM (3/99) 3
2.0 DESCRIPTION
Pan/tilts in the PT550P Series are designed to remotely position a TV camera in
both the horizontal and vertical attitudes. Pan (horizontal) and tilt (vertical) movements are caused by activating small DC motors in the pan/tilt unit. All Pelco units
are equipped with adjustable limits for both pan and tilt, and all motors are equipped
with electrical filtering circuits to suppress RF interference.
The PT573R and the PT573-24R are medium duty, indoor/outdoor pan/tilts designed for V330APT retrofit applications. Both units feature rugged worm gear final
drives to minimize backlash and prevent wind drift, and are fully adjustable for wear.
The PT570P Series and the PT570-24P Series have been engineered to provide
medium duty, indoor/outdoor pan and tilt operation. All units feature rugged worm
gear final drives to minimize backlash and prevent wind drift, and are fully adjustable for wear.
The pan/tilt units of the PT680-24 Series are designed for medium-duty, indoor/
outdoor use. 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.

3.0 MAINTENANCE
3.1 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.
3.1.1 Tightening Drive Chains
Check the pan and tilt drive chains for tension. A movement of 1/32 of an inch to 3/32
of an inch in the chains is acceptable. If the movement of a chain exceeds 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.
3.1.2 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 following:
1. Liberally apply grease to the pan and tilt gears, chains, and sprockets (refer to
Figure 1).
2. Operate the pan and tilt motors to spread the grease across the parts.
Figure 1. Servicing the Pan/Tilt
6 Pelco Manual C325SM (3/99)
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 2.
3.2 RESETTING POTENTIOMETERS
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.
Models with Preset Positioning (PP)
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 for the other potentiometer.
