The locking module detects the position of the guard and the position of the bolt tongue. The position of the guard locking
is also monitored.
Guard locking monitoring can be deactivated using DIP switches (see chapter 13.7. Changing device conguration (using
DIP switches) on page 32).
Important!
For use as guard locking for personnel protection in accordance with ENISO14119, guard locking
monitoring must be active.
The bolt tongue in the handle module is moved into and out of the locking module by actuating the door handle.
When the bolt tongue is fully inserted into the locking module, the locking arm locks the bolt tongue in this position. Depending
on the version, this locking is by spring force or solenoid force.
