A/M Switching

To perform manual operation of the valve using the A/M (automatic/manual) mode
switching mechanism of the FVP110, there needs to be a pressure regulator for the air
supply. To perform manual operation:
Prior to changing the A/M selector switch position, make sure
WARNING
that doing so neither causes an injury nor affects the process.
Changing the A/M selector switch position from M (manual) to
A (automatic) or vice versa during operation causes the valve
stem to temporarily move to a position different from the
position determined by the level of the input signal to the
positioner. If a pressure applied is larger than the allowable
range of pressure gauge, the pressure gauge may be
damaged.
