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 LD2100. If no voltage is present at terminal block,
check the circuit (breaker) or power supply the LD2100 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 LED's are illuminated, contact RLE Technologies for further
troubleshooting.
Cable Break Alarm 1 Verify that the leader cable from the 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.
