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.

3.The weight of the camera, lens, and enclosure shall not exceed 15 lb (6.81 kg) for the PT270 Series and PT280 Series or 20 lb (9.08 kg) for the PT175-24P or PT180 Series.

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.

CAUTION:

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 zoom 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 feature long-life 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.

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.

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

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 for 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 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.

3.2.2Chain 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 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.
