In order to determine the stroke positions 0 % and 100 % in the valve, calibration is
required on initial commissioning:
Prerequisites
• AC 24 V power supply
• Red safety clamp has to be removed, see commissioning notes .
• Housing cover removed
Calibration
1. Short-circuit contacts in calibration slot
(e.g. with a screwdriver)
2. Actuator moves to «0 %» stroke position (1)
(valve closed)
3. Actuator moves to «100 %» stroke position (2)
(valve open)
4. Measured values are stored

green LED is lit permanently;
position feedback U active, the values
correspond to the actual positions
A lit red LED indicates a calibration error.
The calibration can be repeated any number of times.
The LED status indication indicates operational status and is visible with removed
cover.
