Function

Door switch
The Door Lock Switch Assembly consists of a Heating PTC, a Bimetal, a Protection PTC, and a Solenoid. It locks the door during a wash cycle.
1. Operation for door closing – After the system turns on, PTC heating starts up through terminal 2~4’s authorizing the power on. – After PTC heating starts up and before solenoid operation is driven, force the system to the off position through CAM. Door close – Authorizing one impulse through terminal 3~4 (PTC & solenoid) will make the door locked. – Door lock is detected when switches in terminal 4~5 are set closed. CAM rotation will forcibly clear off the connection. The maximum, allowable number of impulse authorizations is 2 Upon the third authorization of the impulse, the position of CAM 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. Normal operation period of PTC heating: 1.5 – 5 seconds (Defects from the development process)
2. Operation for door opening – With a temporary stop, door automatically opens by CAM rotations after authorizing the impulse from the terminal 3 ~ 4 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 position.
