Span Y and U: 0 to 10 Vdc/0 to 20 mA or
2 to 10 Vdc/4 to 20 mA.
Output signal U (position feedback signal)
is dependent on the load resistance.
Above 500 ohm, it is automatically a
voltage signal; below 500 ohm a current
signal.

Transfer
Connections
Figure 7.
If terminal Z for the forced control input is:
− not connected, the valve will follow the Y-signal or the phase-cut signal.
− connected to G, the valve will fully open via control path A → AB.
− connected to G0, the valve will close via control path A → AB.
Signal Priority
1. Hand wheel position Man or Off
2. Forced control signal Z
3. Phase-cut signal
4. Signal input Y
