Wiring to the searchlight
The RCL-300A searchlight is supplied with a 15-foot integral wire
harness. If you must lengthen the wire harness, use heavy duty wire to
minimize the voltage drop. This is especially important for the WHITE 12
AWG lamp power, BLACK 12 AWG lamp ground, ORANGE power wire
and BLUE ground wires.
Following the wiring scheme above and
Appendix C. use the supplied butt
connectors to connect the Master
Controller to the searchlight.
Wiring the Point Pad™
The RG-59 coax cable is supplied
without the “F” connectors attached for
ease of routing. After the Coax cable
has been routed, strip the insulation and
crimp the “F” connectors in place.
Screw the “F” connectors to the Master
Controller and the Point Pad™.
Wiring to the power supply
The power source must be a fused 12
VDC, 30-amp supply or a 24 VDC, 15-
amp supply. Following the wiring scheme in Table 1, use the supplied
butt connectors to connect the Master Controller to the power source.
Refer to Table 2 for proper wire size for connection of the input power
lines.
NOTE: As per the wiring scheme, the ORANGE wire is connected to the
positive terminal and the BLUE wire is connected to the negative
terminal of the power source.
CAUTION: HID light systems, when first turned on, have a high
inrush current requirement of 25 amps. If you activate the light and the
lamps flicker on and off repeatedly, check the voltage being supplied.
This condition can be experienced with voltage input of less than 11.5V.
Functions of the URC-300
The URC-300 Master Controller is designed to perform up to six
different duties on searchlights, winches and other electrical devices.
The Master Controller provides optimum voltage to ensure brightest
performance and long lamp life, regardless of boat system voltage
fluctuations. The Master Controller is compatible with devices requiring
12 VDC through 24 VDC operation.
