Control loop (Code 57)
−
Actuator is blocked.
−
Positioner attachment has shifted
subsequently.
−
Insufficient supply pressure
−
Check attachment.
−
Check supply pressure.
•
[ ]
–
Zero point (Code 58)
−
Mounting arrangement or link-
age has slipped.
−
Valve trim, particularly with soft
seat, is worn.
−
Check valve and positioner at-
tachment.
−
Calibrate zero.
We recommend to re-initialize the
positioner if zero deviates by more
than 5 %.
•
[ ]
•
Inconsistent data
memory (Code 59)
The error is detected by automatic monitoring and corrected automatically.
–
•
Internal device error
(Code 60)
−
Electromagnetic interference
−
Reset initialization.
−
Re-initialize positioner.
–
•
Kp too low (Code 61)
Proportional-action coefficient Kp
level lower than 3 was detected dur-
ing initialization.
−
Activate volume restriction in
positioner output.
•
[ ]
•
x signal (Code 62)
−
Actuator's measured value re
-
cording failed.
−
Conductive plastic element de-
fective.
−
Return positioner to SAMSON
for repair.
–
–
w too small (Code 63)
−
The set point (w) is lower than
3.7 mA.
This state is indicated on the posi-
tioner display by LOW blinking.
−
Check set point (w). If neces-
sary, restrict lower limit of cur-
rent source to ensure that a cur-
rent below 3.7 mA cannot be
issued.
•
[ ]
–
i/p converter (Code 64) Current circuit of i/p converter inter-
rupted.
Return positioner to SAMSON for
repair.
–
–
Hardware (Code 65)
Confirm error and select 'Automat
-
ic' operating mode. If not success
-
ful, reset initialization and re-initial-
ize the positioner.
–
•
Control calculation
(Code 67)
Confirm error. If this is not possible,
return positioner to SAMSON for
repair.
–
•
Pressure sensor
(Code 72)
Pressure sensor(s) for supply air
and/or signal pressure defective
Return positioner to SAMSON for
repair.
