B2.4 Checking head actuator operation manually on the bench
Checks
There are two micro switches in the body of the actuator, one, X, is positioned at the bottom on
the side of the motor Z, the other, Y, is positioned at the top on the rod side W. They signal the
limits (bottom and top respectively) of rod travel to the circuit board controlling squeegee
raising and lowering.
The linear travel of the cam K on the rod actuates one of the two micro switches (bottom X or
top Y). When one of the micro switches is actuated, it makes a mechanical noise (a sort of
click) which indicates actuation.
