General
The door lock part consists of the following:
• Door lock A41 that contains
-an actuator that locks the door lock and
which also has two built-in micro switches,
S4a and S4b. The actuator is bi-stable,
i.e., it has two stable positions: locked
door and unlocked door. The actuator
must receive a pulse to lock and unlock
the door lock. S4a and S4b are both
closed when the door is locked.
- micro switch S3 that is closed when the
door is closed.
- An emergency opening arm/emergency
opening button that can be used to open
the door lock in an emergency.
• Door lock control A31 that is situated in the
front control unit of the machine. This card
controls the door lock function and whether
the drum is empty and not rotating. It locks
and unlocks the door lock when the
programme unit requests door locking or
unlocking.
