Control Panel not Calculating
Proper Length of Cable 1) First verify the proper wiring order into terminal block TB2. Wiring
color code should be as follows from left to right: White, Black, Green
and Red.
2) Go into calibrate in the setup menu on the LCD display. Enter the total
footage of sense cable (orange) on the system and calibrate. 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 from the end of the sense cable. Disconnect the first section
of cable from the LD5000 control panel, where it joins to the second
section of cable. Install the End-of-Line terminator at the end of the
first section of sense 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 sense cable. If the
leak is calculated correctly, remove the end-of-line terminator;
reconnect the sense 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, please contact RLE Technologies for
support.
Cable Contamination Alarm Unit
Displays: “Cable Contaminated
@ XXXX Ft” 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 LD5000 before reinstalling it
under the floor.
NOTE
Contamination and/or physical damage to the cable is not covered
under warranty. For all other troubleshooting concerns and questions
