Function
Circuit in the MAIN PCB / Wiring Diagram
The Door Lock Switch Assembly consists of a DC Motor, a Bimetal, a Protection PTC, Sensing Point.
It locks the door during a wash cycle.
1. Operation for door closing
- After the system turns on, Micom sending motor locking signal.
- 12V motor is working.
- Spring that connected with motor shaft is working.
- The hook that connected with spring is pushed out.
- Door lock is detected when switch sensing point is detected lock position.
- The motor stop.
- Door locked
The maximum, allowable number of impulse authorizations is 3
- Upon the third authorization of the impulse, the position of hook goes back to the door-open
position.
- Authorizing the impulse occurs in 4.5 seconds upon input for max performance and two
authorization processes are allowed at most.
2. Operation for door opening
- With a temporary stop, door automatically opens by hook moving after micom send open signal
and the power turns off – maximum of 3 times of the authorizing period
- Upon the fourth authorization of the impulse, the position of CAM goes back to the door-close
