10.4 Tune parameters
(PATH: MENU / PID Setup / Tune Parameters)
This menu assigns control to a measurement and sets the setpoint, tuning parameters and non-
linear functions of the controller through a series of screens.
10.4.1 PID assignment & tuning
Assign the measurement, a, b, c, or d to be controlled after ”PID on_”. Set the Gain (unitless),
integral or reset time Tr (minutes) and rate or derivative time Td (minutes) needed for control.
Press [ENTER]. Gain, reset and rate are later adjusted by trial and error based on process re-
sponse. Always begin with Td at zero.
10.4.2 Setpoint & deadband
Enter the desired setpoint value and the deadband around the setpoint, where no proportional
control action will take place. Be sure to include the units multiplier u or m for conductivity.
Press [ENTER].
10.4.3 Proportional limits
Enter the low and high proportional limits -the range over which control action is required. Be
sure to include the units multiplier u or m for conductivity. Press [ENTER].
10.4.4 Corner points
Enter the low and high corner points in conductivity, pH, dissolved oxygen units and the respec-
tive output values from -1 to +1, shown in the figure as -100 to +100%. Press [ENTER].
