Error code
Code Description and Cause
Action
MT ERR L
- Positioner is improperly installed
- Positioner is not level to the ground at 50% point.
Lever is at lower position than actual 50% point
- Reinstall the positioner
- Ensure the feedback lever does not
touch the stopper at 0% and 100%
MT ERR H
- Positioner improperly installed
- Positioner is not level to the ground at 50% point.
Lever is at higher position than actual 50% point
- Reinstall the positioner
- Ensure the feedback lever does not
touch the stopper at 0% and 100%
CHK AIR
Valve does not operate when the positioner receives
“Full Open” signal during Auto Cal
- Check supply pressure levels
RNG ERR
Operating angle is too small due to improper
positioner installation
Adjust the mounting bracket so the
positioner can be mounted closer to
the actuator
C
Error of 10% or more persists for more than 1 minute
- No valve movement
- High level of valve friction
- Changes in setting pressure of actuator
- Perform BIAS calibration
- Check setting pressure of actuator
D
I value reaches a maximum or minimum limit
- Changes in valve friction
- Changes in setting pressure of actuator
- Perform Auto Cal
- Check setting pressure of actuator
B
- Pv Span – Pv Zero range is below 500
- The angle of the feedback lever is too small
- Reinstall the positioner
- Ensure the feedback lever does not
touch the stopper at 0% and 100%
- After reinstallation perform AUTO1
F
- Full Open/Close elapsed time is less than one
second
- Actuator size is too small
- Use variable orifice
- Use larger actuator
G
- Pv is below 100
- The angle of the feedback lever is too large
- Reinstall the positioner
- Ensure the feedback lever does not
touch the stopper at 0% and 100%
- After reinstallation perform AUTO1
H
- Pv is over 4000
- The angle if the feedback is too large
- Reinstall the positioner
- Ensure the feedback lever does not
touch the stopper at 0% and 100%
- After reinstallation perform AUTO1
