NIGHT SCAN CHIEF
OPERATING INSTRUCTIONS
ments shown on the wiring diagram. To electrically connect the Night Scan Chief, proceed as fol-
lows:
1. Remove the three screws from the left cover of the base (as viewed from the back of the unit)
and remove the cover.
2. Run the Bulkhead Cable from the HHRC connected to the bulkhead or the PMRC Control
Cable into the bottom of the base. Run all power cables into the bottom of the base.
5.6.1

Wiring Remote Control Cable to the Base Board

The Bulkhead Cable (or PMRC Control Cable) connects the bulkhead, Remote Control, and
Base Board.
3. Connect the wires from the Bulkhead Cable (or PMRC Control Cable) to the green J4 con-
nector located on the top left of the Base Board ensuring the wires match the color strip on
the J4 connector. Connect the J4 connector to the Base Board.
5.6.2

Wiring DC Source Power to the Mast Control Circuit

The mast control system requires DC power regardless of what power is required by the lighting
circuits (AC or DC). Source DC power is provided by the installer from the vehicle battery. The
mast system will operate with 12VDC or 24VDC source power. The power supply must be capa-
ble of supplying 14 Amps to the mast at 12VDC (or 10 Amps at 24VDC).
The Base Board contains a 20 Amp fuse to protect the mast control circuits from over-current.
events. The installer is responsible for providing the means to remove/isolate power from the
mast and permit the operator to follow proper lock-out tag-out procedures for maintenance or
troubleshooting.
Power cables for the mast controls are provided by the installer. The cables must:
• Be type SJOOW or equivalent.
• Be 10 AWG (or 6mm
• Have a maximum length for acceptable voltage drop of 70 feet (21 meters).
4. Connect the DC battery power to the +VIN (red or white) and COM (black) connections on
terminal block TB4 on the lower left side of the Base Board.
5.6.3

Wiring Source Power to the Light Circuits

The lighting circuits consist of two (2) independently powered circuits: left and right. Depending
on the light package installed on the unit, the source power for the left and right light circuits will
change to match the light fixtures. Be sure to confirm the installed light fixture voltage require-
ments before applying light power to avoid damaging equipment.
