29 Blocked button
A button is constantly pressed.
- Inspect the buttons.
- If the buttons look OK, the control board needs to be replaced.
30 Voltage Low
Too low supply voltage has been detected.
- Verify that the voltage is above 21V.
31 Safety stop
The sensor target has moved past the top limit of the sensing range, and
the control unit has locked itself in a safe mode to avoid damaging the
control unit housing.
- Verify that the actuator stroke length is compatible with the control unit.
For example, the stroke length of the SSV long stroke valves is too long for
the V50 housing.
- Verify that the yellow sensor target that was supplied with the control unit
is fitted correctly.
