2. Forced control signal Z
3. Phase-cut signal Phs
4. Signal input Y
If the electronics module is replaced or the actuator turned through 180 °, the valve’s
electronics must be recalibrated. For that, the hand wheel must be set to Auto.
The printed circuit board has a slot (position 3, preceding page).
Calibration is made by bridging the contacts located behind the slot using
a screwdriver. The valve will then travel across the full stroke to store the
end positions.

While calibration is in progress, the green LED will flash for about 10 seconds (also refer
to «Indication of operating state»).
