Integral Time
When the Gain Form setting is Standard, this value is divided into the integral of the
normalized error (area under the error curve), then multiplied by the Gain to determine
the integral component of the calculated output percent.
Integral Gain
When the Gain Form setting is Parallel, this value is multiplied by the integral of the
normalized error (area under the error curve) to determine the integral component of
the calculated output percent.
Derivative Time
When the Gain Form setting is Standard, this value is multiplied by the change in error
between the current reading and the previous reading, then multiplied by the Gain to
determine the derivative component of the calculated output percent.
Derivative Gain
When the Gain Form setting is Parallel, this value is multiplied by the change in error
between the current reading and the previous reading to determine the derivative com-
ponent of the calculated output percent.
Reset PID Integral
The PID Integral Value is a running total of the accumulated area under the error curve
(Current Integral). When this menu option is selected, this total is set to zero and the
PID algorithm is reset to its initial state.
Minimum Output
Enter the lowest possible output value (normally 0%).
Maximum Output
Enter the highest possible output value as a percentage.
Off Mode Output
Enter the output mA value desired when the output is in Off mode, or being Inter-
locked, or if the Output Time Limit has expired, or during a calibration of the sensor
being used as an input. Also if there is a Probe Wash programmed for the sensor, and
the Sensor Mode option is set to Disable the output during the Wash cycle (if the Sen-
sor Mode option is set to Hold the output holds its last setting and the Integral is not
updated during the Wash). The acceptable range is 0 to 21 mA.
Error Output
Enter the output mA desired when the sensor is not giving the controller a valid signal.
The acceptable range is 0 to 21 mA.
Input
Select the sensor to be used by this output.
Direction
Set the control direction. This setting is used to determine the sign of the calculated
error (current process value versus set point) and allows flexible control with only posi
-
tive values for all PID tuning parameters.
Input Minimum
The low end of the sensor input range, used to normalize errors into percent of full scale
units. These values are set to the nominal range of the selected input sensor by default.
Input Maximum
The high end of the sensor input range, used to normalize errors into percent of full scale
units. These values are set to the nominal range of the selected input sensor by default.
Gain Form
Select the PID Equation Format used to enter tuning parameters.
