1 Check with a DVOM (multi-meter) for AC or DC input power on the lower left
hand terminal block on the SeaHawk 10K. If no voltage is present at the
terminal block, check the power supply and circuit breaker that power the
SeaHawk 10K. If voltage is present but no LEDs are illuminated, go to step 2.
2 Contact RLE Technologies for further troubleshooting and evaluation.
Cable Break Alarm 1 Verify the leader cable from the sensing cable run is plugged into TB2, the
terminal block marked “Cable.”
2 Verify the End-of-Line terminator (EOL) is installed on the end of the orange
sensing cable run.
3 A section of sensing cable may be damaged or faulty. To isolate a section of
damaged sensing cable, 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 you do not find a faulty section of cable and the cable break
alarm does not clear, go to step 4.
4 If the sensing cable is all functional, the leader cable may be damaged or faulty.
To test the leader cable, power down (shut off) the control panel. Remove the
terminal block marked “Cable” from the unit. Remove the four leader cable
wires 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 and reapply power. 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.
