VA-715x Electric Valve Actuator Product/Technical Bulletin 7
4. Set the signal fail position jumper to select default
position of fully up or fully down. If the signal is
lost at the actuator (open connection), the actuator
will default to the pre-designated position of full up
or full down.
5. Apply voltage specified by application
requirements to drive the actuator to the full up
position using the following chart:
Table 5: VA-7152 Calibration Values
Application Values
Calibration Values

1-9
0-5
1-4
5-10
6-9
Note: Use of the calibration values in Table 5 will
ensure proper shutoff throughout the life of the
valve (accounts for seat wear).
• DA: full up (minimum voltage)
• RA: full up (maximum voltage)

6. To ensure that the valve stem is in the full up
position, turn the zero adjust knob (shown in
Figure 17) 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 to the actuator back 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 Table 5.
9. To ensure that the valve stem is in the full down
position, adjust the stroke potentiometer fully
Clockwise (CW) until the valve stem reaches the
end of stroke.
10. Slowly turn stroke potentiometer Counterclockwise
(CCW) until LED goes off.
11. Adjust voltage to drive actuator to the full up
position. Verify zero adjustment.
12. Check for proper operation using the desired
minimum and maximum operating voltages. Allow
the actuator to operate through several complete
cycles.
Note: The LED will remain on for 3-10 minutes after
the actuator has completed operation cycle.
13. Replace the cover and secure with the screw.
The unit is ready for operation.
