When the door has been locked by the door handle, the locking arm is
turned and activating the microswitch S3 in the locking unit. When the
3
programmer knob is turned to position I, switch S30 is closed, the delay unit
receives voltage and the coil is locking the door. And then switch S4 is
closed and the program can start.
In order to prevent the door from being opened directly after the final
extraction (roll out time can be about 2-3 minutes) but at the same time limit
the delay time after the program to about 35 seconds, the delay unit has a
time relay and works as follow:
• The time relay motor K62 receives voltage even if the ON/OFF switch
S1 is in position OFF. This means that the contact of the time relay
normally is in position 12-13 directly form start and when the drum is
rotating with wash or distribution speed. During this circumstance one of
the capacitors is disconnected and at the same time the 39 kΩ
resistance is short circuited. The door can now be opened 35 seconds
after a power cut out or when the programmer knob is turned to 0.
• At extraction relay K9 or K10 is activated and the voltage to time relay
motor K62 is interrupted. The contact of the tie relay switch over to
position 11-12 and the delay unit now keeps the door locked about 3-3,5
min. when the programmer knob is turned to 0 or a power cut off. After
the extraction it takes two minutes (120 l machine) resp. three minutes
(220 l machine) before the contact of the time relay go back to position
12-13.
