Limit setting procedure

ISOLATE MAINS BEFORE SETTING LIMITS

AVOID CRAMMING WIRES INTO LIMIT ENCLOSURE AS IT MAY AFFECT CAM MOVEMENT
Follow the steps below:
1. Manually position the door in the centre of the opening.
2. Position one cam to depress a switch and the other so that it is well clear of the switch (note which switch it is that you have
depressed).
For controls with up and down functions:

Supply power and activate control in the upward direction.

If the door travels up, then the limit switch which is engaged by the cam is the CLOSED limit.

If the door doesn't move it is at the OPEN limit.

Continue to Step 3 below
For single button controls:

Supply power and push the button.

If the door travels up, then the limit switch which is engaged by the cam is the CLOSED limit.

If the door travels down, then the limit switch which is engaged by the cam is the OPEN limit.

Continue to Step 3 below
3. Isolate power and adjust the limit cams to depress the switches when the shutter reaches its OPEN and CLOSED positions.
4. Supply power and cycles the door between the OPEN and CLOSED positions. Adjust cam position if necessary.
WARNING
Limits are extremely sensitive, a small cam movement may correspond to a large amount of shutter travel.
