Malfunctions
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 P4 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 direc-
tion when NAMUR attachment is used.
1
Recommended action Reset error code (see section 9.1).
Check positioner mounting and re-initialize the positioner.
E9
to
E15
Device error (internal) Return positioner to SAMSON AG for repair.

9.3 Emergency action
Upon failure of the air supply or electric signal, the positioner vents the actuator, causing
valve to move to the fail-safe position determined by the actuator.
The plant operator is responsible for emergency action to be taken in the plant.
Emergency action in the event of valve failure is described in the associated valve documen-
tation.
