Door lock
The door lock is electromechanical with twin sa-
fety breakers. The lock is bi-stable, i.e. the lock 
must be given an active signal from the program 
unit to lock as well as unlock the door. 
A separate circuit integrated in the program unit 
checks and controls the locking and unlocking 
of the door through a lock module. The circuit 
has separate controls that the drum is empty 
and that it is stationary. Through sensors in the 
lock module, the circuit checks the door’s clo-
sed and locked position. Together with other 
controls the program unit conducts, this will 
guarantee the door cannot be opened by mis-
take. 
The machine’s door and door lock are descri-
bed in more detail in the section 
Door and door 
lock.
