Figure4-3 Forced Fully Open and Closed Values
Handling Precautions:
- Specify values such that the forced fully closed value is smaller than the forced
fully open value.
If the forced fully closed value is equal to the forced fully open value, the valve
performs the ON/OFF operation.
- The settable range is between -200% and 50% for the forced fully closed value
and between 50% and 200% for the forced fully open value.
- If you adjust the span after auto setup, the forced fully open value is
automatically changed to the value calculated by subtracting 1% from the
overstroke percentage.
- The forced fully closed and open values each have a hysteresis difference of
0.1%.
- When the valve is forced fully closed (open), Working Setpoint shows the value
for the fully closed (open) status.

Initial setting of SI system unit and non-SI system unit is as follows. You can not change
the initial setting.
If the non-SI system unit is needed, order kg/cm

or psi at the time of purchase.
SI system: kPa, MPa, Bar
Non-SI system: kPa, MPa, Bar, kg/cm

This unit setting is invalid in the LUI display. Only the kPa is valid in the LUI display.
