When the actuator is driven by a 3-position or DC 0...10 V control signal, it generates a
stroke which is transmitted to the valve stem.

The valve opens / closes in proportion to the control signal at Y.
At DC 0 V, the valve is fully closed (A
When power supply is removed, the actuator maintains its current position.
When the AC / DC 24 V supply is applied for the first time, the actuators calibrate
themselves independent of the control signal. In this process, the actuator drives the
valve to the mechanical end stops and stores the associated positions permanently in
the form of electronic values. The positioning signal is only active on completion of this
calibration process. Calibration takes about 60 seconds.
If the calibrated actuator is used with some
other valve (e.g. a replacement valve), it must
be recalibrated.
1. Unscrew screws
2. Remove cover
3. Connect the 2 contacts behind the slot
for about 1 second.
The calibration can only be made
correctly if the actuator is fitted to a
valve (refer to «Equipment
combinations»).
