Change the Alarm Value
Change AL1 value for example to "5.0" (AL1 active, if PV exceeds SV
over 5.0)
Autotuning (AT)
Temperature control using digital PID controllers have automatic
auto-tune functions. During the auto-tune period the PID controller
controls the power to the process and measures the rate of change,
overshoot and response time of the plant. This is often based on the
Zeigler-Nichols method of calculating controller term values. Once
the auto-tune period is completed the P, I &D values are stored and
used by the PID controller.
Use AT function to automatically calculate and set the optimize PID
value for your system
