NIGHT SCAN POWERLITE, POWERLITE XTREME, AND POWERLITE HDT
OPERATING INSTRUCTIONS
Stowed Limit Switch: This limit switch activates when the mast reaches the horizontal stowed
position. After this switch activates, the controller drives the RCP into the saddle until a specified
current limit is achieved for 0.5 seconds. This drives the RCP into the saddle ensuring a tight fit
for vehicle transport. The stowed limit switch is activated by a magnet located on the tilt
mechanism. The switch location is adjustable and is factory set for a horizontal mounting surface.
If the vehicle surface is not flat, this switch may need to be adjusted for proper stowing of the
mast. See Section 7.5.3 for optional adjustment procedure.
Tilt Actuator: This actuator tilts the mast.

Safety Valve: This valve prevents over-pressurization of the mast system.
Air Control Valve Assembly: The air control valve assembly consists of the extend and exhaust
valve and factory set regulator to control pressure into the mast. Optionally, an air compressor
can replace the air control valve assembly. The mast does not have a switch indicating the mast
has reached its full extended height. When the mast is deployed, the operator should release the
extension button on the hand held control. If the operator keeps the button pressed, the system
will continue to build pressure until the safety valve blows off to relieve pressure.
Labels: Extra warning labels are provided to attach near the operator control station.
Power Converter: The Power Converter is standard with the Night Scan Powerlite HDT, but it is
optional with other Night Scan Powerlite models. The system uses a 12 to 48 volt DC to DC
power converter (Figure 5-13). The power converter has a 58 volt, 30 amp fuse (P/N: 221033) on
the output side. Operating the power converter above 150°F (65°C) may cause damage to the
unit.
