Troubleshooting
Latching fault when actuating the escape release
In order to achieve monitoring of the locking device in category 4, PL e according
to EN ISO 13849-1, an internal monitoring logic system is integrated into every
locking module.
Result: The MGB system enters into a latching fault when the escape release is
actuated (refer to the “System status table LEDs on interlocking/locking module”
Note:
The system might not enter into a latching fault if the escape release is actuated
very slowly.
Fault reset
Proceed as follows:
1. Acknowledge via output bit
O0.1
(in the data block for the diagnostic func-
tion).
2. Close safety guard if necessary and switch guard locking on.
¨
The system is in normal mode again.
