4-12
4-2-10 Input Calibration
Calibrates the input signal (4 mA, 20 mA).
Select [Device] → [Maintenance] → [Input Calibration].
• Calibrate the 4 mA signal
Set after making the current input (controller output) 4 mA.
• Calibrate the 20 mA signal
Set after making the current input (controller output) 20 mA.
4-2-11 Pressure Sensor Adjustment
Adjust the zero point of the pressure sensor.
Select [Device] → [Maintenance] → [Pressure Sensor Adjustment] → [ZeroAdjustment].
Shut off the supply air pressure before zero adjustment.
4-2-12 Simulation
The following two operations can be changed.
Handling Precautions:
The input signal should be 5 mA or more. If it is lower than 5 mA, the device
does not operate normally.
(1) Dummy Input Signal
Specify the pseudo input signal (0% to 100%) and operate the valve. Regardless of the
actual input current, the desired input signal can be sent to the device.
Select [Device] → [Maintenance] → [Simulation] → [Dummy Input Signal].
(2) Dummy Drive Signal
Specify the pseudo EPM drive signal (0% to 100%). Regardless of the actual input
current and travel, the desired EPM drive signal can be output from the device.
Select [Device] → [Maintenance] → [Simulation] → [Dummy Drive Signal].
Cautions
When a simulation is running, it is dangerous to leave it unused for more than 10
minutes, as this will cancel out the setting, and the valve may start moving.
Ensure ahead of time that there will be no injuries or effects on process if the valve is
moved.
