a.
Manual valves (MIV-M)
i.
Manually operate back to the closed position. Stop when the red light is lit.
b.
Electric valves (MIV-E)
i.
Use gearmotor to operate valve to the closed position and allow the
switches to stop rotation.
ii.
The lamps should sequence from flashing red/green to red then the motor
should stop.
21.
Measure the disc position. Refer to figure 10, the valve disc edge should be an equal distance
within ±1/16 inch from this reference point.
22.
If measurement is OK proceed to step 23. Otherwise loosen gearbox adapter mounting
screws and manually turn the handwheel 1/8 turn in one direction and tighten mounting
screws. Repeat steps 20 and 21. If the measurement is worse than before loosen gearbox
adapter mounting screws and manually turn the handwheel ¼ turn in the opposite direction
and tighten mounting screws. Repeat steps 20 and 21.
23.
When the disc, in the closed position, is within the ±1/16 dimension the closed position me-
chanical stop can be set.
a.
Manual valves (MIV-M)
i.
Tighten the screw until it stops. Do not over tighten. Operate valve in both
directions. Check lamp operation and disc stop position, if necessary, back
out screw a small amount until lamp and stop sequence properly.
b.
Electric valves (MIV-E)
i.
Operate the valve open then closed. See that motor stops, the red light is lit,
and valve disc is in the closed position.
c.
Tighten the mechanical stop until it just touches the segment gear, then back out ½
to ¾ turn. Lock in place.
d.
Operate the valve open then closed. See that the motor stops electrically and not
against the mechanical stop. When the motor stops operating, the handwheel
should be able to rotate about ¾ turn before stopping against mechanical stop. If
not back out setscrew another ¼ turn and repeat step.
24.
Now operate the disc to the open position. The mechanical stop can be set.
a.
Manual valves (MIV-M)
i.
Tighten the screw until it stops. Do not over tighten. Operate valve in both
directions. Check light operation and disc stop position, if necessary, back
out screw a small amount until lamp and stop sequence properly.
b.
Electric valves (MIV-E)
i.
Operate the valve to the open position. See that motor stops, the green
light is lit, and valve disc is in the open position.
ii.
Tighten the mechanical stop until it just touches the segment gear, then
back out ½ to ¾ turn. Lock in place.
iii.
Operate the valve closed then open. See that the motor stops electrically
and not against the mechanical stop. When the motor stops operating, the
