Possible settings:
- analog I 4-20mA
- analog I 0-20mA
- analog U 0-10V
For correct operation the suitable signal input type regarding to the connected sensor has
to be selected.
Sensor type:
Terminals:
- analog I 4-20mA
- analog I 0-20mA
The actual value is represented by a current
signal connected to following terminals:
X3/2 -> Sensor 1
* X3/4 -> Sensor 2
- analog U 0-10V
The actual value is given from a voltage signal
connected to following terminals:
X3/6 -> Sensor 1
* X3/5 -> Sensor 2
* … Sensor 2 is not available for the SINGLE Inverter configuration

0420 SENS. RANGE
20mA = 10.00 Bar
Sensor range
Possible settings:
0.00 – 10000
Determines the end value (=20mA or 10V) of the connected sensor.
The maximum sensor range -> 20mA = 100% of the sensor range must be set.
For example:
10 bar pressure sensor
=> 20mA = 10bar
0.4 bar differential pressure sensor
=> 20mA = 0.4 bar
Flowmeter (Flowrate= 36m³/h)
=> 20mA = 36m³/h

0425 SENS. CURVE
linear
Sensor curve
Possible settings:
linear, quadratic
Internal calculation based on the actual value
Possible setting and its application:
• linear:
Pressure control, differential pressure control, level, temperature and
flow control (inductive or mechanical).
• quadratic: Flow control using an orifice plate together with a differential pressure
sensor.
