− Positioning value upon input signal failure = Last position
The actuator stem remains in the last position that the valve moved to before failure of the
input signal.
The error message is cleared and the actuator returns to closed-loop operation if the input
signalmoveswithin0.2Vor0.4mAofthelowerrangevalue.

End position guiding
The actuator stem moves to the end position earlier if the end position guiding function is ac-
tive.
− End position guiding when the value falls below the limit
Theactuatorstemmovestothe0%positionwhentheinputsignalreachesValue below
limit (end position guiding).
− Endpositionguidingwhenthevalueexceedsthelimit
Theactuatorstemmovestothe100%positionwhentheinputsignalreachesValue
above limit (end position guiding).
When 'Value below limit (end position guiding)' = 0% and 'Value above limit (end position
guiding)' = 100%, the end position guiding function is deactivated.
