MONT
• The current valve mounting situation is shown. If the value is far
away from 0, the valve will suffer from a poor linearity and hysteresis.
Move the positioner and try to reach closer to 0 for the best linearity
and hysteresis.
- How to set MONT
For information, on “MONT”, the operating range (0~10kΩ) of the potentiometer is displayed.
- Step 1: Select MONT and push the ENT button one time, and the valve will be fully open or
closed and also the actual valve position angle will be shown.
- Step 2: Push the ENT button one time, and the valve will be fully open or closed and also the
actual valve position angle will be shown.
- Step 3: Push the ENT button one time, and the actual valve middle position angle will be shown.
It shows the middle position angle between two ends (fully open and closed) measured
through the above procedures of Step 1 and Step 2. Move the positioner upwards or
downwards so that the valve position angle can reach closer to 0. And fix the mounting
bracket tightly.
