C Troubleshooting
Note Contamination and/or physical damage to the cable is not covered under warranty. For all
other troubleshooting concerns and questions regarding this product, contact RLE
Technologies.
Control Panel not
Calculating Proper
Length of Cable
1 First verify the proper wiring order into terminal block marked
“Cable.” 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
(Configuration menu via the Web Interface). 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.
Control Panel not
Calculating Proper
Leak Distance
1 Check the distance on the cable run to verify that the control
panel is monitoring. Verify there is no water along the cable run.
Check to see if multiple leaks are present on the cable. The first
leak should be read and latched by the system; however, if the
system is updated or simultaneous leaks occur (2 or more) within
30 seconds of the initial leak, the system may display the
average distance (distance of the first leak + distance of the
second leak / 2). If no water is present, go to step 2.
2 Power down (shut off) the control panel and remove the End-of-
Line terminator (EOL) from the end of the sensing cable. Locate
the first section of sensing cable from the LD1500 control panel.
Where it joins to the second section of cable, disconnect and
install the EOL terminator at the end of the first section of
sensing cable. Turn power back on at control panel. Once the
control panel runs for five to ten minutes, use a damp cloth, rag
or paper towel and place it on the end of the orange sensing
cable. If the leak is calculated correctly, remove the EOL
terminator; reconnect the sensing cable and move down to the
next section of cable. Repeat this process until a faulty reading is
obtained. If the reading is off at the first section of cable, there
may be miscalculations from the LD1500 unit, please contact
RLE Technologies for support.
Cable Contamination
Alarm
1 To clear a contamination alarm, the cable must be removed and
cleaned. Usually the cable can be cleaned by pulling it through a
clean damp rag.
2 If the cable is contaminated by oil, glycol or chemicals, the cable
can be washed. Use a mild detergent solution of 1 capful to 2
gallons lukewarm water (<105°F). Agitate the cable in a suitable
container, rinse with clear lukewarm water and wipe dry with a
clean towel. The cable may also be cleaned by wiping it down
with Isopropyl Alcohol.
3 Retest the cable by connecting it to the LD1500 before
reinstalling it under the floor.
