6 Commissioning RMS 621
38 Endress+Hauser
Setup → Temperature
Dependent on the model of the unit between one and six different temperature sensors (RTD, TC)
can be connected. A single sensor can be used for two or all three applications, see address
"Terminals" in the following table.
Function (Menu
address)
Parameter set-up Description
Identifier Temperature 1-6 Identifies the temperature sensor, e.g. ’inflow temp.’.
Signal type Please select
4-20 mA
0-20 mA
Pt100
Pt500
Pt1000
Default
Selection of the temperature sensor signal type. On setting
"Default" the unit operates with a fixed predefined
temperature.
Sensor 3-wire
4-wire
Set up sensor connection mode in 3- or 4-wire connection.
!
Note!
Selectable only for Pt100/Pt500/Pt1000 signals.

Allocates the terminal to which the temperature sensor is
connected. It is possible to use one sensor (temperature signal)
for more than one application. Select the respective terminal to
which the signal required is connected in the application.
(Multi calculations possible)
!
Note!
Terminal identifier X-1X (e.g. A-11) describes a current input,
the identifier X-2X (e.g. E-21) indicates a pure temperature
input. The type of input is dependent on the extension cards.
Engineering Units °C; K; °F Engineering units of the temperature measurement.
Format 9; 9.9; 9.99; 9.999 Number of decimal points
Signal damping 0 to 99 s
0 s
Time constant of a 1st order low pass filter for the input signal.
This function is used to avoid display fluctuations on high
fluctuating input signals.
!
Note!
Only selectable for the 0/4 to 20 mA signal.
Start value -9999.99 to 999999 Start value for the temperature signal at 0 or 4 mA.
!
Note!
Only selectable for the 0/4 to 20 mA signal.
End value -9999.99 to 999999 End value for the temperature signal at 20 mA.
!
Note!
Only selectable for the 0/4 to 20 mA signal.
Offset -9999.99 to 9999.99
0.0
Moves the zero point on the sensor curve. this function helps
by fine adjustment of the sensor.
!
Note!
Only selectable for the signal0/4 to 20 mA signal.
Default -9999.99 to 9999.99
20 °C or 70 °F
Set-up of a predefined temperature with which the unit will
continue to operate as "default" if the sensor signal fails.
Average temp. Not used
2 sensors
3 to 8 sensors
