special positions depending on the installed valve head. A failure in this process
means either that the movement couldn’t be performed properly or it was not
noticed correctly by the sensor.
Probable cause Suggested actions
1 Mechanical problems. Friction too high or
blockages on the valve drive’s motor or on
the valve head.
