Use this “PID TUNING” submenu screen to tune the con-
troller to the dynamics of the pH process:
The screen settings are:
•
Proportional gain (-99.99 to +99.99 with “ - “ for reverse
action and “ + “ for direct action)
•
Integral gain (0.00-50.00 repeats/minute)
•
Derivative gain (0.00-10.00 seconds)
•
Transit time setting (0-2000 seconds); displayed only
when the type VEL (velocity algorithm) is selected for
controller operation -- see PID MODE screen below
NOTE:
Integral gain can be disabled by entering “0.00” to
provide only PD controller action.
Use this “PID MODE” submenu screen to configure the
controller to your application requirements:
