Warning
•
During auto-setup, the valve moves from fully open. Take appropriate measures be-
forehand to ensure that the movement of the valve will not cause injury or have an
effect on the process.
Step Procedure
1 Confirm that the input signal is 4 mA or higher.
2 Select [Device] >> [Setup] >> [Basic Setup] >> [Auto Setup] to execute the method.
3 Following the screen display, execute the operation. The control valve will start to move.
This operation takes about two to three minutes.
4 When the operation ends, “Auto Setup is Completed” is displayed on the screen. When
control via the input signal becomes possible, auto-setup ends.
5 Vary the input signal and check the movement to confirm that adjustment is being
performed appropriately.
