Door lock
The door lock is an electro-mechanical type with
double safety switches. The lock is bi-stable, i.e.,
it needs to receive an active pulse from the
control in order both to lock and unlock the door.
A separate printed circuit board, called door lock
control, can be fitted onto the programme unit.
This board controls locking and unlocking. The
card has separate checks for empty drum and
stopped drum. Together with the checks built into
the programme unit, this guarantees that the
door cannot be opened by a mistake.
The door lock on the machine is described in
detail in section
29. Door and door lock .
