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

- 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
