11. Cycle the valve several times at both the
fully open and fully closed actuator cam to
see if there is any movement like a second
hand on a clock. If there is, this means
that the cam needs adjustment. When the
valve is open all the way, the green light
should be on and not flashing. When it is
closed, the amber light should be on and
not flashing. Please refer to the cam
adjustment information in this section to
resolve any movement/flashing light
issues.
Changing the Guide Bushings
To change the guide bushings, follow the steps
listed below.
1.
Open the valve about half way.
2.
Remove the two bolts holding the old
bushings in place and remove the old
bushings.
3.
Place the new bushing into position.
4.
Insert the bolts, attach the nuts and
tighten.
5.
Run the valve up and down. If any
slowing of the valve movement or jamming is noticed, loosen the bolts on one bushing and pull
the valve body away from the center of the valve and re-tighten the bolts.
6.
If slowing or jamming still occurs, loosen the guide bushing bolts on the opposite side and repeat
the operations of step 5.
7.
The valve should be opened and closed several times. If it operates as it should, the bushings are
changed correctly.
