4-6
- Rotary sub/Other
When the distance between the feedback lever of the rotary actuator (around 60°) and
the pin is shorter than the distance from the valve shaft
• Valve Closed Position
Feedback lever position of fully closed
- Down (Standard)
- Up
• Feedback Lever Motion
Specify UP or DOWN as the operation of the feedback lever when output air pressure
OUT1 increases. This setting is automatically set by the auto setup.
• Pilot Relay Type
Pilot Relay Type (Single Acting or Double Acting) is indicated. The type is automatically
determined by auto setup.
• Positioner Action
The EPM moving direction that is automatically determined by auto setup is indicated.
Handling Precautions:
The positioner operation direction is determined by the hardware of the
main unit. This function cannot be used to switch the operation direction.
If you want to switch the operation direction, contact one of our service
representatives.
• Electrical Fail To
Open or Closed is automatically set as the fail safe direction when the electrical signal is
“Disconnected” based on the settings for Valve Closed Position, Feedback Lever Motion,
and Positioner Action.
• Air Fail To
Open or Closed is automatically set as the fail safe direction when the supply air
pressure is “Disconnected” based on the settings for Valve Closed Position and
Feedback Lever Motion.
This item is not displayed when Pilot Relay Type is Double Acting.
4-2-5 Control Configuration
Control parameters are PID operation parameters for controlling the control valve and
are selected based on Actuator Size and Friction Level.
Select [Device] → [Configuration] → [Control Configuration].
- Actuator Size
Specify Param 1 to 6 or Param A to C depending on the operation speed and capacity
of the actuator.
To specify every PID operation parameter, select Custom. (For details, consult with one
of our service representatives.)
