5-1. Auto/Manual selection switch
The Auto/Manual switch selects the control method for the pneumatic output from the
positioner to be either automatic operation or manual operation.
Automatic operation
An air pressure output corresponding to the input signal is output from the SVP.
See Fig.5-2.

The supplied air pressure is output directly from the positioner.
This allows manual operation using a pressure regulator.
See Fig.5-3.
CAUTION
The double acting actuator has no manual operation function.
WARNING
The valve may move suddenly when the A/M switch is operated. Prepare yourself and the
process in advance so that the process is not adversely affected when the valve operates.
