4.
Before connecting the linkage, run unit back and forth to make sure
that the stroke of the actuator matches that of the lever to be moved.
If the stroke of the actuator needs to be adjusted, proceed as follows:
a.
Run unit back and forth and note how the adjustment pins
contact the limit switches to set the stroke length.
NOTE
Before attempting any adjustment of the limit switches,
turn the power off to prevent any accidental short circuits
or injury.
b.
Determine which limit switches must be adjusted. Loosen the
set screws, with the Allen wrench supplied, and slide the pins in
or out to adjust the stroke as needed. Do not over tighten set
screws.
CAUTION
Do not attempt to adjust the stroke by bending the
contacts on the limit switches. This is the most frequent
mistake which causes failure of the limit switches and
inevitable failure of the entire unit.
5.
With the proper stroke set, connect linkage to lever and run unit back
and forth to make sure that the actuator runs freely without any
binding.
NOTE
Be sure that the actuator contacts the limit switch before
reaching the end of its mechanical stroke. Failure to do so
could result in damage to the actuator.
6.
Replace actuator cover.

Ready to begin operation.
