Limit Switch Setup Continued
3.
While observing cams of the limit
switch raise the lift a foot or so and
take note of the direction that the
cams are rotating. It is good
practice to mark this direction of
rotation; an example is shown to
the right.
4.
Loosen the 5/8” retainer nut
before adjusting the limits; also
shown to the right.
5.
The small flathead screws that
surround the retainer nut are used
to adjust the limits.
a.
Colors correspond to the wire colors.

It is best to make adjustments while looking at how the
cam engages the black roller on the microswitch.
c.
The top and bottom limits will hit on opposite sides of
their microswitches based on cam rotation.
d.
1/8th turn on the adjustment screw is about 6-8 inches
of travel
e.
On each test of adjustment run the lift a few feet away
from the limit and then back to the limit.
f.
3-stop
: Set top and bottom limits before attempting to
set the middle stop, you also must start from one of the
outer limits on each test of your middle adjustments.
g.
If the lift touches the ground during this process you will
need to rewrap the lifting cables.
6.
Whenever limits are set tighten the retainer nut
