Problem Action
Control Panel will not
Power Up
1 Check with a DVOM (multi-meter) for AC or DC input power on
the lower left hand terminal block on the LD1500. If no voltage is
present at terminal block, check the circuit (breaker) or power
supply the LD1500 control panel is powered by. If voltage is
present, go to step 2.
2 Contact RLE Technologies for unit replacement and/or
evaluation. If voltage is present and no LEDs are illuminated,
contact RLE Technologies for further troubleshooting.
Cable Break Alarm 1 Verify that the leader cable from the SeaHawk Water Leak
Detection Cable (sensing cable) run is plugged into terminal
block marked “Cable.”
2 Verify that the End-of-Line terminator (EOL) is installed on the
end of the orange sensing cable run. If present at the end of the
cable run, go to step 3.
3 Remove the EOL terminator from the end of the cable run and
install it onto the end of the leader cable coming from the control
panel. If the condition clears, there is a damaged/faulty section of
sensing cable. Start moving the EOL terminator to the end of
each section of sensing cable to isolate the faulty section. If the
condition does not clear, go to step 4.
4 Power down (shut off) the control panel. Remove terminal block
marked “Cable” from the unit. Remove the four conductors from
the leader cable wire going into the four position terminal block.
Install a jumper wire between pins 1 and 2 and another jumper
wire between pins 3 and 4. Reinstall the terminal block back into
TB2. If the cable break condition clears, there is a problem with
the leader cable. If the condition does not clear, contact RLE
Technologies for further support.
