Cause/recommended action
Actuator transit times detected during initialization
are too short making optimal positioner tuning
impossible.
Minimum transit times:
K = 25: ≥150 ms
P
K = 50 to 100: ≥380 ms
P
use a screw restriction or reduce gain K
Supply pressure varies. Mounting incorrect.
Re-initialize the positioner.
Supply pressure is too low, actuator leaks, incorrect
travel adjusted or pressure limit function activated.
When MAX is selected for P5 code (nominal range):
the measuring span of the lever is too small (incorrect
lever, incorrect pin position). Initialization is canceled
when the angle of rotation of the positioner shaft is
smaller than 11°.
position and setting. Re-initialize the positioner.
No supply air, mounting blocked.
signal.
Re-initialize the positioner.
Wrong pin position, wrong lever, wrong attachment
direction when NAMUR attachment is used.
Check positioner mounting and re-initialize the
positioner.
