TROUBLESHOOTING
* Current Draw Too Low:
In a low current situation, the controller
will retry the command to the station up to 3 times.
The DUAL48M display will show the station number when it is
sending the command to the decoder.
If the current does not increase, the station number will disappear
for a few seconds. This indicates that the draw did not increase as
expected.
After 4-5 more seconds, the station number will re-appear, during
the retry attempt.
If low current draw continues, the number will disappear again.
After 3 unsuccessful attempts, the station number will disappear,
and the Fault message will appear on the ICore controller
facepack display.
The slow blink of the station number is an indication that either
the specied decoder, or its solenoids, are not connected or
operational.
When a healthy decoder and solenoid are activated, there is
no need for the retry attempts, and the station number will not
appear to blink.
If No Stations Will Activate:
1. Verify that slide lock is in the Power On position and that
power is on to the DUAL48M module (display appears).
2. Check DUAL48M for “Line Open” message. This means the
two-wire path is disconnected from the controller.
3. Check between the controller and the rst decoder to verify
that the two-wire path is connected.
If No Stations Will Activate Beyond a Certain Station Number
(followed by multiple station faults): Likely break in two-wire path
beyond station 1.
1. Identify failing stations from Fault messages.
2. Identify decoder locations and layout on plan or in wiring
path.
3. Begin with last working station, and look for break beyond
that point.
4. If multiple two-wire paths are in use, disconnect other paths,
and troubleshoot one path at a time.
