Electrical signal
Available signal types:
• 0.5 - 3.5 V
• 0-5 V
• 0-10 V
• 0-20 mA
• 4-20 mA.
Sensor range, minimum value
Set the minimum value of the connected sensor.
Sensor range, maximum value
Set the maximum value of the connected sensor.
10.9.1 Setting two sensors for differential measurement
Two analog sensors must be installed and connected electrically to
measure a parameter at two different locations in a system.
The pressure, temperature and flow parameters can be used for
differential measurement.
• Set the analog inputs according to the measured parameter:
Parameter
Sensor 1,
measured
parameter
Sensor 2,
measured
parameter
Pressure, option 1 Inlet pressure Discharge press.
Pressure, option 2 Press. 1, external Press. 2, external
Flow Pump flow Flow, external
Temperature Temperature 1 Temperature 2
If you want to use the Con. diff. press., Con. diff.
temp. or Const. flow rate control modes, you must
configure both sensors as Feedback sensor.

Pt100/1000
To set the input, choose one of the below settings.
Function
You can set the inputs to these functions:
• Not active
• Feedback sensor
The sensor is used for the selected control mode.
• Setpoint influence
The input signal is used for influencing the setpoint.
• Other function
The sensor input is used for measurement or monitoring.
Measured parameter
Select one of the below parameters to be measured in the system
by the sensor connected to the input.

1 Liquid temp.
2 Temperature 1
3 Temperature 2
4 Differential temp.
Not shown Ambient temp.
Measuring range
-58 to 399 °F (-50 to +204 °C).
