D Troubleshooting
Cable Break Alarm 1 Verify that the leader cable from the SC cable run is plugged into
terminal block TB7.
2 Verify that the end-of-line terminator is installed on the end of the
orange sense cable run. If present at the end of the cable run, go
to step 3.
3 Remove the end-of-line terminator (EOL) 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 SC cable. Start moving the end-of-line
terminator to the end of each section of SC 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
TB7 from the main board. 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.
Control Panel not
Calculating Proper
Length of Cable
1 First verify the proper wiring order into terminal block TB7. Wiring
color code should be as follows from left to right: White, Black,
Green and Red.
2 Calibrate your cable. To do this, adjust the Resistance per Foot
(see 5-8.14: Resistance / Foot on page 19 for details). If the
condition does not change, please contact RLE Technologies.
The control panel is pre-calibrated from the factory. The overall
footage should be within 5% of actual installed length.
