LIMIT SWITCH
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 settings 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 108)
3)
Remove the slotted retaining screw and slide the
cam plate out from operator frame. (Figure 109)
(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 110) 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
109)
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 108)
