SECTION 21. TUNING PROPORTIONAL CONTROLLER
The Proportional Controller is not active unless your meter has analog output capabilities. The
menu will display whether analog output is present or not. This function allows you to tune your
controller provided you have analog output capabilities. Select either Time Proportional Control
or Analog and Proportional Control.
* Select Time Proportional Control by setting “S.3=P” in Setpoint 1 Configuration
( “S1.CF” - refer to Section 11).
or
* Select Analog and Proportional Control by setting “O.3=P” in Output Configuration
( “OT.CF” - refer to Section 15).
Include the meter in the process loop and turn on the meter. Allow enough time for the system to
settle, then do the following.
1. Press the / DEV button. The meter momentarily shows “DEV” followed by a blinking
value. This value is the deviation (error) between Reading and Setpoint 1 values. If
there is no error (error is zero), your controller is tuned. If a value other than zero shows,
proceed with step 2.
2. Press RESET button. The meter shows “TUNE” , tuning your controller and canceling
any error. Once tuned, the meter shows “RST” and returns to the run mode.
Allow enough time for process to settle before proceeding with “TUNE” procedure. If any
error happens during this procedure, meter will flash “ER 4” and abort the tuning. You
have to restart the procedure.
“TUNE” will be active if your meter has analog output capabilities.
3. Press the / DEV button. Verify that blinking value is zero. If blinking value is not zero,
repeat step 2.
