Temperature inputs
Function (menu item) Parameter setting Description
Identifier Temperature 1-6 Name of temperature sensor, e.g. ’Temp 1’ (max. 12
characters).
Signal Select
4-20 mA
0-20 mA
Pt100
Pt500
Pt1000
Default
Selects the signal of the temperature sensor. If ’Default’ is set,
the device works with a fixed default temperature.
Sensor type 3-wire
4-wire
Configures the sensor connection in 3-wire or 4-wire
technology.
!
Note!
Can only be selected for the Pt100/Pt500/Pt1000 signal.
Terminals None

E-3-8
Defines the terminal for connecting the temperature sensor. It
is possible to use a sensor signal for several applications. For
this, in the application in question, select the terminals where
the sensor is located (multiple selection possible).
!
Note!
The term in brackets X-1X (e.g. A-11) describes a current
input, the term X-2X (e.g. E-21) a pure temperature input. The
type of input depends on the extension cards.
Unit °C; K; °F Physical unit of the measured temperature.
!
Note!
Only visible if the "Random" system unit has been selected.
Format 9; 9.9; 9.99; 9.999 Number of places after the decimal point
!
Note!
Only visible if the "Random" system unit has been selected.
Signal damp 0 to 99 s
0 s
Time constant of the first order low pass for the input signal.
This function is used to reduce display fluctuations in the event
of severely fluctuating signals.
!
Note!
This can only be selected for the 0/4 to 20 mA signal.
Start value -9999.99 to 999999 Start value for the temperature with 0 or 4 mA.
!
Note!
This can only be selected for the 0/4 to 20 mA signal.
End value -9999.99 to 999999 End value for the temperature with 20 mA.
!
Note!
This can only be selected for the 0/4 to 20 mA signal.
Offset -9999.99 to 9999.99
0.0
Shifts the zero point of the response curve. This function is
used to adjust sensors.
!
Note!
This can only be selected for the 0/4 to 20 mA signal.
Default -9999.99 to 9999.99
20 °C or 70 °F
Sets the temperature which is worked with if the sensor signal
fails and the ’Default’ signal is set.
Alarm response See Setup ’Flow inputs’.
Temperature mean value Unused
2 sensors
3 to 6 sensors
Mean value computed from several temperature signals
(See Section 11.2.1 for details of the 'Mean value
computation')
