EB 8389 EN
Possible reasons
− Initialization cycle takes
too long (> 90 s). The
positioner returns to its
previous operating mode.
− Supply pressure too low.
Actuator too slow.
− Positioner cannot find fixed
travel/angle stops.
Actuator transit times detected
during initialization are so
short (< 0.3 s) that optimal
positioner tuning is impossible.
Pin position not entered for
nominal range (NOM) or
substitute (SUB) initialization.
ATO/ATC switch defective.
Positioner detected during
initialization that actuator
permits no emergency control
mode without feedback. In
case of a travel sensing error,
positioner vents Output or A1
in double-acting actuators.
Error while the reference
graph 'Drive signal diagram
steady-state (d1)' or 'Drive
signal diagram hysteresis (d2)'
is automatically plotted during
initialization
Error in control parameters.
Error in digital potentiometer
parameter.
Error in data from production
calibration.
Error in parameters not critical
to control operation.
Internal device error
Recommended action
− Check supply pressure.
− Install a volume booster.
− Adjust travel/angle stops.
− Re-initialize positioner.
− Activate volume restric-
tion in positioner output.
− Re-initialize positioner.
− Enter pin position and
nominal range.
− Re-initialize positioner.
Return positioner to
SAMSON for repair.
For your information only.
No further action required.
Check and perform new ref-
erence test, if necessary.
Confirm error. If not success-
ful, reset initialization and
re-initialize the positioner.
Confirm error. If not success-
ful, reset initialization and
re-initialize the positioner.
Return positioner to
SAMSON for repair.
Confirm error.
Return positioner to
