Troubleshooting
Before requesting a service call, please check that the following actions have been taken:
■
Equipment has been tested according to the following checklists.
■
Telephone assistance has been obtained from the Service Center in order to isolate the
problem.
Interference
■
The settings of the DIP switches (ON/OFF) were reviewed according to the instruction
manual.
■
The relay is connected straight and tightly to the plug-in socket.
■
All 11 connecting cables were screwed properly and stable to the corresponding plug-in
socket.
■
All 11 connection terminals are clean and free from any dirt.
■
The inductive loop(s) were installed properly. (see laying instructions for inductive loops)
Fault Analysis
Source of Fault
Cause
Action
By using a two-channel loop
detector both channels are
responding identically.
Both detectors are working on
the same frequency.
Different inductive loops (in
length and number of loops)
must be installed and
connected.
The loop detector doesn't
react or has contact issues.
The connections are dirty.
Please clean the connection
terminals with a suitable
contact cleaner.
(e.g. Contact
Chemistry 60)
The loop detector doesn't
react to high vehicles.
Insufficient sensitivity.
The switching threshold must
be increased via the DIP
switch (sensitivity boost).
The loop detector is triggered
without any passing vehicle.
The distance between
inductive loop(s) and
moveable metallic parts (e.g.
gates) is too small.
The distance between the
edge of the inductive loop(s)
and moveable metallic parts
must be at least 1 metre.
