Door lock control A31
This card serves to perform a safety check of the
door lock function.
The card checks the water level using level guard
B2 and the drum speed by way of a rotation
sensor B3. The card receives a signal from the
CPU card when the door should be locked or
opened.
The door lock control controls the door lock coil
and the door lock does not open or close until the
card itself and the programme unit have verified
that the drum is not turning and that there is no
water remaining in the drum.
The door lock control is described in detail in
section 29. Door and door lock.
