MICRO SWITCH ADJUSTMENT

General Notes about micro switches:
2LS: DROP-OUT ARM SWITCH
Switch roller must ride against drop-out arm when drop-out arm is fully closed. Switch must trip before
drop-out arm is fully open and reset before being fully closed.
1LS: CAM SHAFT SWITCH
Switch arm must be positioned on its shaft so that the machine's cam shaft is in home position at the end
of cycle.
1LS: INTERNAL SWITCH ADJUSTMENT
With switch mounted on the machine, switch arm must travel 18° to 22° from rest position to trip (1LS
should trip in the upward direction only). To check, turn off power and use a wrench to advance the cam
shaft until the arm of 1LS is free. The diagram below may be used to check this adjustment.
1LS ADJUSTMENT PROCEDURES
1. Trace or photocopy the 1LS diagram shown on the following page. Cut out the reproduction along
the dotted line.
2. Slip the diagram behind the machine's limit switch arm so that the actual arm exactly covers the arm
in the diagram.
3. Secure the diagram in place to the cable fitting using a piece of tape. This will allow the cover to be
removed if necessary without having to remove the diagram.
4. Raise the arm to determine if a click occurs when the rollers edge is between the two arcs shown on
the diagram. (The two arcs correspond the roller travel of 18° to 22°).
5. If the click occurs too early or late, remove the limit switch cover.
6. If the click occurs too early, turn the adjustment screw clockwise
and re-check the travel. If it occurs too late, turn the adjustment
screw counter-clockwise and recheck.
7. Replace the cover after the limit switch has been properly adjusted.
