Part Description
Main unit Holds the electronics module, EPM (electro-pneumatic converter
module), and VTD (position sensor).
Pilot relay Amplifies the pneumatic signal from the EPM (electro-pneumatic
converter module) and converts it to a pneumatic signal for the
actuator.
Feedback lever Acquires the motion of the control valve and transmits it to the
VTD (position sensor).
Auto/Manual switch Switches the control method for the pneumatic output between the
automatic operation state and the manual operation state. Refer to
“5-2-1: Auto/Manual selection switch” on page 59. for information
on operating procedures.
