Distribution speed
Relay K3 connects the distribution speed windings on the wash motor. The
following conditions must be met for relay coil K3 (13) to be energised:
•
The door must be closed and locked and the programmer knob must be
in position I (see ”Power supply and start” sequence).
•
Row M, stop (1) must not be programmed.
The machine runs at distribution speed when the drain valve, controlled by
relay K31, is open. The following conditions must be met for relay K31 (5)
to be energised:
•
The out-of-balance switch must not have tripped (breaks K53:51-52
(2) power supply).
•
Row K, drain (3), must be programmed.
•
Row 3b (4) in the reverser must be closed (see diagram below).
This contact closes when the wash motor is running and the drum is
rotating in the same direction as at distribution speed. This prevents
unnecessary stress on the motor, belts and drum bearings when
engaging distribution speed.
When K31 energized, K31:51-52 (7) cuts the power supply to relay K2,
which de-energises the motor wash windings. K31:51-52 also cuts the
power to reverser motor M22 (8). The reverser stops, which means that
reverser contact 3b (4) remains closed until the motor is running at
distribution speed.
When K31 is energized, closes K31:43-44 (9), which means that relay coil
K3 (13) is energised and connect the motor distribution speed windings.
