3. The GAIN parameter adjusts the proportional PID term Increasing the GAIN value will increase the output response to the process deviation The RESET parameter adjusts the integral PID term Increasing the RESET value will increase the output response to the process deviation The RATE parameter adjusts the derivative PID term Increasing the RATE parameter will increase the output response to a process variable change Setting the GAIN RESET or RATE values to 0 will disable the propor tional integral or derivative functions respectively The derivative function is usually not used in applications where there is an immediate response to the process variable from the control output signal The derivative function by nature will cause the output signal to appear unstable as it responds to the changing process variable signal Input filtering FilterVal set greater than 0 is always required when using derivative Using derivative may not be desirable in a application where the output controls a mechanical valve The Dimension uses the difference input span between the input high limit InptHiLim and input low limit InptLowLim for the PID calculations If setpoint limiting is desired change the input high and low limit values before starting your loop tuning Should you have tuned your loop already and are required to change the input high or low limit values change your PID parameters as follows New input high limit New i
