Switch Adjustment
Switches are pre-set at the factory when assembled to the
cylinder. They can, however, be field adjusted in the
following manner:
Disconnect all electrical supply circuits.
Remove limit switch box cover.
If adjusting the switch on the head end of the cylinder
(the end of the cylinder with the piston rod), retract the
rod fully.
If adjusting the switch on the cap end of the cylinder,
extend the piston rod fully.
Turn the hex head adjusting screw (see illustration)
counter-clockwise until the limit switch clicks on. After
the switch has clicked on, turn the hex head adjusting
screw clockwise until the switch clicks off, then continue
to turn clockwise an additional 1/4 turn.
Replace the limit switch box cover.
Reconnect the electrical supply circuits.
