5.3.3 If readjustment of the positions is needed
without cycling the actuator:
After adjusting the mechanical limit stops on the
actuator, in such a way that the switch points are
not reached (i.e. reducing the stroke), the Module
will not give proper position feedback.
The easiest way of readjustment of the exact
positions is performing the initialization procedure
(see §5.2).
During initialization the actuator will cycle 2 or 3
times. When it is not allowed that the actuator/
valve unit cycles, the new switch point can be set
with the following procedure:
1 Check if the actuator is correctly mounted to the
valve, if yes:
2 Push the button, corresponding with the actual
position of the actuator, for 3 seconds (“Open”
or “Closed”).
3 The corresponding LED starts flashing.
4 Release the button and push again until LED
burns constantly, Status LED indicates “init
successful”.

Action Reassignment buttons
Set to factory default Push both buttons before power up, and than hold until Status LED is constant
on. Release and observe LEDs to indicate default
Initialize While powered up push both buttons until Status LED starts blinking
Reassignment “Open” end position Push “Open” button until “Open” LED starts flashing, release button and push
again until LED is constant on, Status LED indicates “init successful”.
Reassignment “Close” end position Push “Close” button until “Close” LED starts flashing, release button and push
