Depending on the closure of a series of contacts (8-9-10), the timer transmits to the electronic control board
(14) the codes which determine the operations to be carried out at the various steps.
The electronic control board, on the basis of the appliance configuration and of the selected options (push-
buttons and selectors) controls the washing cycle:
•
on completion of the cycle phase carried out in a determined position, the board powers a timer motor
via a TRIAC: the timer motor (11) advances to the subsequent phase.
•
controls the closure of the pressure switches
•
controls the temperature of the washing solution via the NTC sensor (16)
•
via a second TRIAC, the board directly powers the drum rotation motor (15) and controls the speed of
rotation according to the signal received from the tachometric generator (T). The direction of rotation is
determined by the closure of the contacts of two relays.
All the remaining electromechanical components in the washing machine are powered via the timer
contacts.

Configuration of timer functions
Configuration of timer functions is effected by setting certain wiring
connectors.

J1 - J2 Connectors which, for the various models, determine the
transmission radio between the drive pulley and the drum pulley and
the speed of the final speed cycle.

synthetics 50ºC, final spin for synthetics C6)
•
"Europe" if a connection is fitted between M9.1-M9.2 (cold water solenoid, maximum temperature for
synthetics 60°C, final spin for synthetics C4)
