6.4 Device configuration
6.4.1 Description of device functions
All parameters that can be read out and setup for the configuration of the temperature transmitter
are listed and described in the following tables. The menu structures in the ReadWin
®
2000 PC
configuration software and in the HART
®
handheld module DXR275/375 are shown in the
following tables.

PV mode For selecting the calculation function of the PV (PV = primary value). The PV is
shown linear at the analog output.
• PV = Sens1
Sensor 1 is the primary value (PV)
•PV = Sens2
Sensor 2 is the primary value (PV)
• PV = Sens1-Sens2
Difference
• PV = (Sens1 + Sens2)/2
Average of sensor 1 and 2
• PV = Sens1 (or Sens2) backup
Sensor 2 becomes PV if sensor 1 fails. An error signal is not output. If the
active backup = switch to redundant sensor, the display shows the "Caution"
icon, the corresponding error number (see chapter 9) and the text 'back'.
• PV = Sens2 (or Sens1) backup
Sensor 1 becomes PV if sensor 2 fails.
• PV = Sens1 (Sens2, if Sens1 > T)
If temperature T is overshot at sensor 1, the measuring temperature of sensor
2 becomes the PV. The system switches back to sensor 1 if the measuring
temperature at sensor 1 is at least 3.6 °F (2 °C) below T. S1 or S2 appears on
the display to indicate which sensor is currently active. The temperature-
dependent switchover means that 2 sensors can be combined, which each
have certain advantages in different temperature ranges.
