DESCRIPTION

All heavy duty pan/tilts can operate with loads up to 100 pounds (45.4 kg). Rugged hightorque motors with adjustable worm-gear final drives ensure long operational life and driftfree operation. All models are manufactured from cast and/or plate aluminum with all internal parts corrosion-protected steel or aluminum.

The PT1250 Series and PT1280 Series are capable of auto/random scan operation with the addition of the Pelco solid-state auto/random scan joystick control.

The PT1253R is equipped with variable frame scan capabilities (adjustable from 2-9 seconds) and interfaces with other manufacturers' control systems for frame scan operation. This pan/tilt can be used in place of the Vicon V390APT pan/tilt.

The PT1250EX/AMS meets the rigorous requirements for weather and dust-proof electrical equipment for installations in salt-air environments.

Pan/tilts in the PT1260EX Series meet the rigorous requirements of explosion-proof and dust-ignition-proof electrical equipment for installation and use in hazardous locations. PT1260EX Series units are suitable for use in salty conditions such as aboard ships and on sea coasts.

MAINTENANCE

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.

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.

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.

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 (except PT1250EX/AMS and PT1260EX Series).

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 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.

➛

WARNING

: The knife-blade included in the brake

kit is very sharp. It should be handled carefully and disposed of properly after use.

NOTE

: This section does not apply to the PT1250DC Series.

Figure 2. Sealant Locations

MOTOR BRAKE REPLACEMENT

To order replacement motor brakes, specify part number 1250BRAKE. The kit consists of four springs, four Teflon pads, two screws, and a small knife-blade for removing the old brake pads.

1. Remove the large rectangular heat sink from the back of the pan motor. Remove the four springs. Do not disturb the silicone heat sink compound. It ensures the transfer of heat to the heat sink and MUST be present when the heat sink is replaced.

2. Use the knife blade to remove the worn pads, as follows: a. Insert the knife blade into the opening and press firmly into the brake pad. b. Before trying to remove the brake pad, twist the knife-blade. This will loosen the

worn pad and make removal easier.

c. Gently twist the blade as you pull the worn pad out.

3. Insert the four new brake pads and four springs. Replace the heat sink using the new screws.

Reinstall the cover. If your pan/tilt is installed outdoors in an inverted position, apply RTV silicone sealant to the areas circled in Figure 2 (except PT1250EX/AMS and PT1260EX Series).
