Error Codes and Recommended Actions
If the positioner doesn’t work properly and
on LCD blinks, try to take action as below.
Error
Code
Cause
Symton
Action
CMLO
Low input current
(3.7mA)
Data on LCD are shown too dim
or too bright.
Re-check 4 – 20mA input signals.
CMHI
High input current
(20.5mA)
IGMI
Down Speed Long
Slow operation
The actuator is too big.
Use the air volume booster.
IGMX
Up Speed Long
H/RX
HART Rx Error
HART signal failure
Re-set and re-connect will be done after
2.5 seconds, but it is necessary to check
the communication system in case of a
continuous error.
MONT
Operating angle out
of range
MONT is shown during step 4 and
an auto-calibration process is
finished without completion.
Re-install the SS2L / SS2R positioner.
LOTT
Bias Low
The valve is not closed or moves
slowly.
Loosen a valve packing.
HITT
Bias High
The valve is not open or moves
slowly.
FBFT
Feedback error
(0 - 1%)
PM00 is shown at step 4 and an
auto-calibration is finished
without completion.
Defectiveness of potentiometer socket
contact or PCB board
FBSM
Feedback error
(2 - 9%)
The operating stroke is too small
and the valve doesn’t work
smoothly.
Re-install the potentiometer and increase
the operating angle of the feedback lever.
BAD
PST error
BAD is shown.
Check the valve or increase the response
time of PST.
PONT
Potentiometer Error
Problem of potentiometer
Check the potentiometer
(Potentiometer Ass’y, Board)
RTQ
Coil Error
Problem of coil
Check the coil assembly.
DATA
DATA blinks
