CHAPTER 6 TROUBLESHOOTING GUIDE
6.1 TROUBLESHOOTING
In case loss of PASSWORD at 3L-SP/AP panel, contact ELSA office for master PASSWORD.
Liquid leaked is detected when there is no obvious liquid presence. The possible reasons are as
follows (it is highly recommended to replace the affected section):
The sensing cable was badly contaminated by some chemical for unknown reason.
The sensing cable was coated with glue, epoxy and paint accidentally.
The 2 black sensing wires are in contact or not isolated properly.
Use a bright torch light to identify the location of the physical liquid leaked area which is visible by
naked eye. Some leakage is difficult to be observed due to very small volume of liquid presence
and the environment is not so accessible, then professional help should be required.
Cable break is detected where there is no visible wire cut externally is observed:
Check the continuity of the 4 wires by a multi-meter.
Check that the 4 termination points of the leader cable to the Control Panels are secured
properly.
If leak location is not accurate:
This may probably due to small amount of liquid still exists at different points on the
sensing cable.
Also, it can be due to some contamination with electrostatic dust, transparent chemical or
glue deposited on the cable.
Check the sensing cable with naked eye and clean the cable with dry cloth. If problem
persist and contamination is the cause, then the sensing cable will need to be replaced.
