Water points

The water points are responsible for alternate rinsing and for different
rinsing pressures. They consist of a synchronous motor with gears,
cam disc (B) , microswitch (A) and locking disc (C). The synchronous
motor is actuated via a triac. The controller receives information on the
position of the locking disc (C) from the microswitch (A) which is
actuated by the cam disc (B). The synchronous motor drives the gears
and therefore the cam disc and the locking disc.
The locking disc has three openings and locks the relevant water
channel to the spray arms. Water pressures vary depending on the
position of the locking disc.
