Roper Whitney 10M14-H, Operation Manual

If the Prox Switch requires adjusting, the two (2) nuts threaded on
to the switch can be rotated to move the switch in or out relative to
the Actuation Flag. There is an LED light located at the rear of the
Prox Switch that indicates the switch is activated when the light is
on. The Prox Switch must be close enough to the Actuation Flag to
keep the LED light on the entire time the flag is in front of the
switch.
The location where the Material Return rotates is set by adjusting
the vertical position of the Prox Switch relative to the lower edge of
the Actuation Flag. This position is set at the factory for proper
operation of the Material Return.
The timing for rotating the Material Return can be altered by moving
the Prox Switch up or down: causing the Material Return to rotate
earlier or later during the stroke of the Ram. The position of the
Prox Switch affects the point of rotation of the Material Return
during both the upward and downward motion of the Ram. Once
the new position of the switch is attained, secure the nuts on the
Prox Switch to prevent movement of the switch.
