Motor control

For the motor to operate, it is necessary for row 5a (2) or row 7a (1) to be closed, or
for the level sensor to be shut off (water level is reached) so that point E receives
voltage. The sequence diagram indicates that both rows 5a and 7a are closed
during water filling, spin and tumble cycles. For each wash moment when the drum
should be filled with water, all rows are open and advance is initiated by the level
sensor, point E in the diagram. If for some reason water does not fill into the drum,
the motor stops.

Normal speed (12 second rotation - 3 second pause)

Row 9a (5) remains closed when the motor is running at normal speed. Row 24b
(7) in the timer is supplied voltage via row 18 (6) in the program selector. The latter
row is closed during all programs where the drum rotates at normal speed. Row 24
is located in the timer's built-in reverser, where each stage lasts 3 seconds. The
reverser switches over at normal speed: 12 seconds on, 3 seconds off, 12 seconds
on, etc. Row 24 controls the connection of contactor K1 which in turn activates the
motor wash winding.

Gentle action (3 second rotation - 12 second pause)

When washing is done at gentle action (Mild 30 C and Wool 40 C programs), row
18 (6) in the program selector is de-energised. Instead, voltage is supplied via rows
11a (3) and 22b (4). Row 11a controls how long the motor will rotate during the
program. Row 22b is located in the reverser and switches over at gentle action: 3
seconds on, 12 seconds off, 3 seconds on, etc.

Spin

During the spin cycle, row 9b (5) activates spin contactor K4. As a security
measure, K4:22-21 (10) de-energises K1, preventing the wash winding from being
connected at the same time as the spin winding.
