Operation
Guard locking controlled with SDD commands
}
If guard locking is controlled with SDD commands, the lighting behaviour of the "Lock"
LED is no longer primarily dependent on the switching state 31/Y1. The status of guard
locking is displayed using LED.
}
If guard locking cannot be activated with SDD commands (e.g. no actuator detected), this
is indicated for 10 seconds, as specified in the table. Then it is switched back to normal
condition. There is no display of the unsuccessful activation attempt.

If guard locking cannot be activated with SDD commands, and the actuator is detected,
