SETUP
– Setting up the process controller
These functions specify the type of control.
The procedure is described in the following Chapters "23.2.1" to "23.2.5".
23.2.1.
PV-INPUT
– Specifying signal type for the process actual
value
One of the following signal types can be selected for the process actual value:
• Standard signal
4 ... 20 mA
flow rate, pressure, level
• Frequency signal
0 ... 1000 Hz
flow rate
• Circuit with Pt 100
-20 °C ... +220 °C
temperature
Factory setting: 4 ... 20 mA
When the operating voltage has been switched on, the device looks for connected sensor types
(automatic sensor detection).
When a sensor type (PT 100 or 4 ... 20 mA) is detected, the signal type is automatically implemented in the
PV-INPUT
operating menu.
If no sensor signal is detected, the last setting is retained.
The signal type frequency signal cannot be detected automatically, but must be set manually in the
PV-INPUT
menu.
