Gap PID parameter configuration procedure
step Procedure
1 Select [Device] >> [Setup] >> [Control Configuration] >> [Change Actuator
Size], and set the actuator size to the parameter 0. The PID parameters will be
displayed.
2 Select [Device] >> [Setup] >> [Control Configuration] >> [PID Parameter]. You
will be able to check or modify seven PID parameters (P, I, D, GE, GP, GI, and
GD).
3 Enter values to set the seven respective PIDs. For the SFN version, start the
method and enter the values in order.
4 For the HART® version, send the modified setting to the device using the
transmission button.
4-4-5. Input range
This procedure sets the electric current input value when the valve is fully closed (LRV) and
the electric current input value when the valve is fully open (URV). Values can be entered in
the 4 to 20 mA range. A split range can be specified as well.
Note) Set these values so that the electric current input span (the difference between LRV and
URV) is in the 4 to 16 mA range.
If the span is 8 mA or less, the accuracy will be 1.5 % of full scale.
Input range configuration procedure
The procedure for setting the desired electric current input values is shown below.
Configuration procedure for electric current input values (mA) for valve
fully closed
step Procedure
1 Select [Device] >> [Setup] >> [Input Range].
2 Select [LRV (Shut)], and enter the electric current input value when the valve is
fully closed.
3 Send the modified setting to the device using the transmission button.
Configuration procedure for electric current input values (mA) for valve
fully open (100 % position)
step Procedure
1 Select [Device] >> [Setup] >> [Input Range].
2 Select [URV (Open)], and enter the electric current input value when the valve is
fully open (when the position is 100 %).
3 Send the modified setting to the device using the transmission button.
