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.

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.
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.
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.
6 |
Pelco Manual C325SM (3/99) |
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.
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.
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.
