Function
The door lock locks the door
When the door is closed (closed door lock switch
S3), the programme unit may request door
locking by applying a voltage of 200-240 V on the
door lock controller A31 input X92.
The following check is made by the A31 card
prior to locking of the door:
•
No water in drum
- input X93 from level
guard B2 is closed = 0 V
•
Mot
or not engaged
- input X94 from motor
control U1 open = 5 V
•
Drum not turning
- pulse frequency on input
X95 from rotation sensor B3 less than 0.4 Hz.
When the above conditions are met, the card
A31 outputs a closing pulse on output X96 to the
door lock actuator/coil, which then locks the door.
The micro switches S4a and S4b in the actuator/
door lock are closed when the door is locked.
These micro switches feed voltage to:
•
The output relays
on the programme unit
card. The relays control the machine’s drain
and water valves as well as heater switch-on.
•
Interlock signal
for motor control (input
X302) that releases the motor start prevention
state.
Programme operation is now possible.
