4-9-4 Manual Setup
Individual PID constants can be manually set in the Proportional Band, Integral Time, and Derivative
Time parameters in the Adjustment Level.
Additional Information
Proportional Action
When PID constants I (integral time) and D (derivative time) are set to 0, control is executed
according to proportional action. As the default, the center value of the proportional band
becomes the set point.

4-9-4 Manual Setup
In this example, the Proportional Band parameter is set to 10.0, the Inte-
gral Time parameter to 250, and the Derivative Time parameter to 45.
Operating Procedure
• Setting the Proportional Band
1 Press the M Key several times in the Adjustment Level to
display the p (Proportional Band) parameter.
Adjustment Level
2 Press the U or D Key to set the value to 10.0.
The default settings are as follows:
• Temperature input (°C or °F): 8.0
• Analog input (%FS): 10.0
• Setting the Integral Time
1 Press the M Key several times in the Adjustment Level to
display the i (Integral Time) parameter.
Adjustment Level
2 Press the U or D Key to set the value to 250.
The default settings are as follows:
• Integral/Derivative Time Unit of 1 s: 233
• Integral/Derivative Time Unit of 0.1 s: 233.0
• Setting the Derivative Time
1 Press the M Key several times in the Adjustment Level to
display the d (Derivative Time) parameter.
Adjustment Level
2 Press the U or D Key to set the value to 45.
The default settings are as follows:
• Integral/Derivative Time Unit of 1 s: 40
• Integral/Derivative Time Unit of 0.1 s: 40.0
