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 is 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.
LED Indication Function Remarks, troubleshooting
Green Lit Normal operation Automatic operation; everything o.k.
Flashing
Calibration in progress
Wait until calibration is finished (LED stops
flashing, green or red LED will be lit)
Red Lit Faulty stroke calibration
Check mounting
Restart stroke calibration (by short-circuiting
calibration slot)
Internal error Replace electronics
Flashing
Inner valve jammed Check valve
Both Dark
No power supply
Electronics faulty
Check mains network, check wiring
Replace electronics
As a general rule, the LED can assume only the states shown above
(continuously red or green, flashing red or green, or off).
