DIAGNOSTIC INFORMATIONS
Detailed diagnostic information for an easy troubleshooting of your muting application is available using the following indicators:
•
internal indicators: LED "RUN1" and "RUN2" located on the module front panel,
•
external indicators: muting lamp connected to terminals 48.
In the case of a failure the indicators are indicating a flashing code. There exist two types of errors:
•
FATAL ERRORS are only indicated by flashing internal LED's "RUN1" and /or "RUN2". The muting lamp connected to terminal
48 remains permanently off.
The normally open safety contacts (13/14, 23/24, 33/34) are de-energised and the module needs to be reset by taking the
power off and on after resolving the error cause.
•
APPLICATION AND INSTALLATION ERRORS are indicated by flashing internal LED "RUN1" and the muting lamp connected
to terminal 48. LED "RUN2" is permanently on.
The normally open safety contacts (13/14, 23/24, 33/34) are de-energised, but the module can be restarted pushing the start
push-button after resolving the error cause.

Note (1): It is possible that
- LED "RUN1" and "RUN2" are indicating different error codes or,
- only one LED "RUN1" or "RUN2" is indicating an error code and the second LED "RUN1" or "RUN2" is switched off.
