The behavior of the PID controller is set with:
− Proportional part
Amplification
− Integral part
Integral Time
− Differential part
Derivative Time
Reference percentage channel is shown (simplified). See chapter 7.5.2 "Reference percentage chan-
nel".
Application examples

Pressure control
Flow rate control
Temperature control
Via dataset changeover via control contacts, the PID controller can be adjusted to different operating
points.

The pressure in a process is kept at a constant level by means of a pres-
sure sensor.
The flow rate in a process is kept at a constant level by means of a flow
sensor.
The temperature is kept at a constant level by controlling a fan by means
of a thermostat.
