Message Possible reasons Recommended action
Status
classifica -
tion Single reset
Initialization time exceeded
(Code 53)
−
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.
−
Check supply pressure.
− Install a volume booster.
− Adjust travel/angle stops.
− Re-initialize positioner.
•
[ ]
•
Transit time not reached
(Code 55)
Actuator transit times detected
during initialization are so
short (< 0.3 s) that optimal
positioner tuning is impossible.
− Activate volume restric-
tion in positioner output.
− Re-initialize positioner.
•
[ ]
•
Pin position/fail-safe switch
(Code 56) Pin position not entered for
nominal range (NOM) or
substitute (SUB) initialization.
−
Enter pin position and
nominal range.
−
Re-initialize positioner.
•
[ ]
•
ATO/ATC switch defective. Return positioner to
SAMSON for repair.
No emergency mode
(Code 6)
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. For your information only.
No further action required. •
[ ]
–
Reference test aborted
(Code 81) Error while the reference
graph 'Drive signal diagram
steady-state (d1)' or 'Drive
signal diagram hysteresis (d2)'
is automatically plotted during
initialization Check and perform new ref-
erence test, if necessary. •
[ ]
–
Control parameters
(Code 68)
Error in control parameters. Confirm error. If not success -
ful, reset initialization and
re-initialize the positioner.
•
[ ]
•
Potentiometer parameter
(Code 69) Error in digital potentiometer
parameter. Confirm error. If not success -
ful, reset initialization and
re-initialize the positioner.
•
[ ]
•
Adjustment (calibration)
parameter (Code 70)
Error in data from production
calibration. Return positioner to
SAMSON for repair. •
[ ]
–
General parameters
(Code 71)
Error in parameters not critical
to control operation. Confirm error. •
[ ]
•
Internal device error 1
(Code 73) Internal device error Return positioner to
SAMSON for repair. •
