ADJUSTMENT
ELECTRICAL WARNING

Disconnect or turn off the power supply before
starting any work on the COVANA cover.
Additionally, all electrical work should be
performed by a qualified electrician.
Note: The up and down limit switches have been
factory-adjusted and there should be no need to re-
adjust them.
If adjustments are required to ensure the
COVANA cover does not come in contact with
surrounding obstacles while being raised, the
maximum height may be reduced. Never change the
factory setting of the down limit nor increase the up
limit beyond the factory setting. Failing to do so may
result in equipment damage and/or injury.
1) Disconnect or turn off the power and lock out the
power source.
2) Remove the four slotted screws at the bottom of
the operator and remove the cover. (Figure 88)
3) Remove the slotted retaining screw and slide
the cam plate out from operator frame. (Figure
89) (Be careful not to move the cam wheels.)
4) To reduce the amount of travel in the upward
direction, turn the up-cam wheel counter
clockwise viewed from the cam plate as shown.
(Figure 90) When turning counter-clockwise, for
each cam
wheels’ lot travel (approx. 4°), the
upper cover limit will be reduced by
approximately 5/32 in (4 mm).
5) Once the height is set to the desired position,
return the cam plate to its original position and
ensure that it is properly inserted in the slot of
each cam.
Never operate the system without
the cam plate and retaining screw . (Figure
90)
6) Reinsert the slotted retaining screw to prevent
the cam plate from coming out.
7) Reinstall the operator cover.
8) Turn the power on and test the system.
9) Screw the cover back on using the 4 slotted
screws. (Figure 88)
