Malfunctions
Code Status Description Cause/recommended action Class
E4 Transit time too short
(initialization error)
Actuator transit times detected during initialization
are too short making optimal positioner tuning
impossible.
Minimum transit times:
K
P
= 25: ≥150 ms
K
P
= 50 to 100: ≥380 ms
2
Recommended action Check piping and re-initialize the positioner. Possibly
use a screw restriction or reduce gain K
P
.
E5 Standstill detection is
not possible
(initialization error)
Supply pressure varies. Mounting incorrect.
2
Recommended action Check supply air and positioner mounting.
Re-initialize the positioner.
E6 Travel is not achieved
during initialization
(initialization error)
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°.
2
Recommended action Check supply air, positioner mounting, lever, pin
position and setting. Re-initialize the positioner.
E7 Actuator does not move
(initialization error)
No supply air, mounting blocked.
2
Recommended action Check supply air, positioner mounting and mA input
signal.
Re-initialize the positioner.
E8 Travel signal at lower/
upper limit
Wrong pin position, wrong lever, wrong attachment
direction when NAMUR attachment is used.
1
Recommended action Reset error code (see section 9.1.1).
Check positioner mounting and re-initialize the
positioner.
