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 (or Slider return spring)
⇒ Door close
- Authorizing one impulse through terminal 3~4 (PTC & solenoid) will make
the door lock.
- Door lock is detected when switches in terminal 4~5 are set closed.
⇒ CAM rotation (or Positioning slider return spring) will forcibly clear off
the connection. The maximum, allowable number of impulse authorization is 2.
⇒ Upon the third authorization of the impulse, the position of CAM
(or Slider return spring) goes back to the door-open position.
- Authorizing the impulse occurs in 5 seconds upon input for max
performance and two authorization processes are allowed at most
⇒ Normal operation period of PTC heating : 1-5 seconds.
2. Operation for door opening
- With a temporary stop, door automatically opens by CAM rotations
(or positioning slider return spring) after authorizing the impulse from the
terminal 3~4 and power turns off – maximum of 3 times of the authorizing period.
- Upon the fourth authorization of the impulse, the position of CAM (or Slider
return spring) goes back to the door-close position.
The Door Lock Switch Assembly consists of Heating PTC, a Bimetal,
a Protection PTC, and a Solenoid. It locks the door during a wash cycle.
