Functional description
The W1 fill level switch is designed as a rocker
switch and is integrated in the bottom of the
reservoir. A magnetic rocker mounted on the
agitator is turned downward by the grease re-
sistance when the reservoir is full. A pulse is
created at each revolution of the agitator.
When the minimum fill level is reached, the
resistance the grease exerts on the rocker
subsides. The rocker turns back and the pulses
are interrupted.
