7.2 Adjust Actuator
1) With the breaker closed, and the actuator reset, adjust the
position of the actuator rod by screwing it in or out until
the end of the rod is about 1/64" from the trip paddle.
2) Trip the breaker. Trip the actuator by striking the reset
knob. Lock the actuator rod in position by tightening the
10-32 set screw with an Allen wrench.
3) Adjust the stop nuts as necessary to limit the actuator rod
travel within the limits of the trip bar.
4) With the actuator reset, close the breaker. If the breaker
will not close because the actuator rod is interfering with
the trip paddle, re-adjust the
position of the actuator
rod.
5) Operate the actuator by lightly striking the reset knob.
The breaker should trip. Verify that the trip paddle is not
against its limit of travel.
7.3
Verify Trip Free Operation of the Manual Reset
Actuator
It is very important to verify that with the manual reset
actuator in the trip position it will keep the breaker trip
free.
1) Attempt to close the breaker without resetting the
actuator. The breaker should trip free, if not, increase
the actuator rod travel.
2) Repeat the above until completely satisfied with the
operation of the actuator.
IMPORTANT:
WHEN THE ACTUATOR IS IN THE TRIP POSITION
(NOT RESET), THE BREAKER MUST BE TRIP-FREE.
THE SET SCREW IN THE PLUNGER MUST BE TIGHTENED
TO ENSURE THAT THE ACTUATOR ROD REMAINS IN
PROPER ADJUSTMENT.
