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.

Corrective actions
Apply voltage to A1(+) and A2(-).
If the error is not resetable, contact
your nearest sales office for
assistance.
Select identical modes for channel
1 and channel 2
Select valid mode (see mode
selection table)
Apply supply voltage within
specifications: 24 Vdc +/- 15% at
A1(+) and A2(-)
Check correct functioning of safety device outputs.
Check for broken wires and short circuits
Check safety switches are actuated
within the time frame.
Ensure safety contacts 13/23 to 33/34 are properly
connected and not welded.
Ensure switched current is within specifications.
If the error is not resetable, contact your next sales
office for assistance.
Note the sequence leading to this error.
If the error is not resetable, contact your nearest
