Explanation of the escaper movement before
adjusting the sensor
When the power switch is turned ON, if there is no screw at the site
where the screw is to be picked up, the escaper rotates with the screw
sensor LED off.
The escaper rotates and accepts a screw from the rail.
As the escaper rotates, it brings a screw to the screw pick up site.
At this time, the sensor detects a screw, the LED lights up and the
escaper stops.
When the screw is removed from the pick up site, the LED light goes
off and the escaper rotates to accept another screw from the rail.
This is the correct sequence of operation. Usually, there is no need to
adjust the sensor as it was done when assembled in the factory.
The following are irregular situations that require adjustment:
-There is no screw at the pick up site but,
the LED is on and the escaper doesn't rotate.
-There's a screw at the pick up site,
but the LED is not lit and the escaper rotates

The rotation of the escaper, in the opposite
direction, is a reference point run of the escaper
motor.
The rotation of the escaper, in the opposite
direction, occurs when the power is turned on
and the starting point of the escaper is not
alligned with the reference point of the escaper
motor.
During regular operation, as in the figure above,
the escaper rotates clockwise.
