7. ELECTRICAL NULL ADJUSTMENT
The hydraulic null of the valve is preset at the factory with a tolerance
of
±
2% of rated signal. If necessary, this null can be readjusted by the user of
the valve.
a.
Observe operating instructions for the machine/plant.
Valves with +4 to +20 mA command signal: Do not adjust valve
null! Contact machine/plant manufacturer.
b.
Procedure: Remove the command signal to the valve only by
disconnecting command signal lead at the cabinet.
Do not remove valve mating connector!
Remove cover screw on electronics housing to access the null adjust
potentiometer. Use a small screwdriver (blade width 2.5 mm) to turn
the potentiometer screw either clockwise or counterclockwise. Usually
it will not be necessary to turn the screw more than 2 turns in either
direction (
±
1 turn is equivalent to
±
15% null shift).
c.
While adjusting, watch the actuator (motor) motion to find the null
position. With overlapped valves, turn the null adjust screw carefully in
both directions to just start motion and then back into deadzone
midposition between those two screw positions.
d.
After proper null adjustment, reconnect the command signal lead and
install protective cover screw again.
