Automatic Self-Calibration
When power is applied to the actuator for the first
time, self-calibration takes place. During this
process, both LEDs on the drive flash in red.
1. The stem extends until it reaches the lower
mechanical stop in the valve.
2. Then, the stem retracts until it reaches the upper
mechanical stop in the valve.
3. Self-calibration is complete. The valve and
actuator move to the position dictated by the
control signal.
Manual Self-Calibration
If required, self-calibration can be triggered
manually.
• Fold out and fold back the crank handle twice
within 4 seconds. See Figure 11. Self-
calibration begins.
• The self-calibration can be stopped by folding
out the crank handle again.
Figure 11.
• After calibration is complete, the two stroke
indicator clips can be attached to the
actuator arms. See Figure 12.

CAUTION:
Observe the direction of flow when assembling
the valve and actuator.
