Motor control
Normal Action (12 second rotation - 3 second pause)Row 3b (1) is closed when the motor is running with normal action. From
row 3b the voltage is supplied to row 24b (2). This row is located in the
timer's built-in reserver, where each stage lasts 3 seconds. Row 24b
switches over at normal speed (12 seconds on, 3 seconds off, 12 seconds
on etc.) and controls contactor K1 (4) which activates the motor wash
winding.
Row 21 a-b and 23 a-b (11) switches two of the incoming phases so that
the motor is reversing.
Spin
During the spin cycle, row 16b (3) activates spin contactor K4 (5). At the
same time K4:21-22 (6) de-energises K1, so that the wash speed winding
and extract winding of the motor can not be connected at the same time.
