Timer
Part Number
32661 001
Function
Provides an automatic timing sequence of the wash, rinse, detergent and rinse aid injection
stages in a dishwashing cycle.
Description
The electro-mechanical timer has five cams and a drive motor. The timer cams, rotated by
the motor, operate individual changeover switches in a set timing sequence. The drive
motor is rated at 120 sec per full turn and it is controlled by cam T1 (the cams are counted
from the motor side). Cam T1 is built-in with a rapid start fitting, which provides a quick
actuation of the T1 changeover switch after the power to the drive motor was applied. Cam
T2 controls the wash pump, T3 – the hot rinse solenoid/rinse pump, T4 – detergent
injection time. Cam T5 is for control of rinse aid injection time if an optional rinse aid
pump is fitted.

Replacement
To replace the timer take note of the position of each connection, preferably on paper.
Disconnect all wires and remove the timer from the tray. Compare the cam setting of the
old and new timer to ensure that special settings are duplicated. Fit new timer taking care to
locate cam T1 in the same relative position. Reconnect the wires ensuring that no
termination is under strain. Test the machine to confirm correct operation.
Adjustment
The timer cams T4 and T5 are adjustable. The time settings on these cams can be increased
by making the gap in a cam wider, or reduced by reducing the gap. Use a timer adjusting
tool, supplied with a machine to modify a gap in the timer cams.
