• Top Jumper = 0 to 10 V
• Center Jumper = 0 to 5 V
• Bottom Jumper = 5 to 10 V
2. Set the short/long travel selection jumper:
• Short for stroke lengths 13 mm or less
• Long for strokes over 13 mm
3. Set the direct/reverse action jumper so that the

VA-7152 Adjustments
6. To ensure that the valve stem is in the full up
position, turn the zero adjust knob completely
to the left, until the valve stem reaches the end
of stroke.
7. Slowly turn the zero adjust knob to the right,
and stop as soon as the LED flashes or goes
out.
Note: As the actuator is driving, the LED will be
on. The actuator circuit contains a time out
feature. If calibration takes longer than 3-
10 minutes, the LED will go out giving a
false satisfied condition.
If this occurs, turn off the power, wait
several seconds, turn the power on, and
then readjust the zeroing knob.
8. Apply the input voltage specified by application
requirements to drive the valve stem to the full
down position per calibration value (figure 3).
9. To ensure that the valve stem is in the full
down position, adjust the stroke potentiometer
fully clockwise until the valve stem reaches the
end of stroke.
10. Slowly turn stroke potentiometer
counterclockwise until LED goes off.
11. Adjust voltage to drive actuator to the full up
position. Verify zero adjustment.
