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 (see System status table on page 23).
Note!
The system might not enter into a latching fault if the escape release is actuated
very slowly.
Fault reset
Proceed as follows:
Open the safety guard.
Switch the operating voltage off at the locking module for min. 3 seconds.
As an alternative, 24 V can be applied to the input RST for min. 3 seconds.
The green LED (DIA1) flashes quickly (approx. 10 Hz). A self-test is performed
during this time (approx. 8 s). The LED then cyclically flashes three times.
Close safety guard and switch guard locking on.
The system is in normal mode again.
