Motor control

Normal Action (12 second rotation - 3 second pause)

Row 8 (1) in the program selector is closed during programs ”Warm”, ”Hot”

and ”Permanent Press” when the motor is running at normal action. From

row 8 the voltage is supplied via row 14b (5) to row 24b (7). This row is

located in the timer's built-in reverser, 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 which activates the motor wash

winding.

Gentle Action (3 second rotation - 12 second pause)

Row 10 (2) in the program selector is closed and row 8 (1) is de-energised

during program ”Cold”. This means that the motor is running at gentle

action. From row 10 the voltage is supplied via row 22b (3) which is located

in the motor’s built-in reverser. The rows switch over at gentle speed (3

seconds on, 12 seconds off, 3 seconds on etc.). The voltage is then

supplied via row 14b (5) and 24b (7) to contactor K1 which activates the

motor wash winding. Row 24b does switch over at normal action, but is

always closed when 22b closes.

Spin

During the spin cycle, row 13b (6) activates spin contactor K4 (9). At the

same time K4:21 -22 (10) de-energises K1, preventing the wash winding

from being connected at the same time as the spin winding.

Normal action during tumbling

At stage 48, contactor K1 is supplied via row 14a (5) instead of 14b. The

motor runs at normal speed at this stage regardless of which program has

been chosen.
