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.

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.
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.
