Undetected failure in devices with functional safety
Note the following:
● For the maximum current output signal to be output, set the measuring range within the
● Note that a saturation limit > 21.5 mA increases the risk of undetected failures. (Page 162)
● When you configure your process control system, the analog input must distinguish

Introduction
Depending on the application of the device that you have selected using the "Application"
parameter, you have the option of selecting a unit:
● Level
● Volume
● Volume flow
● Mass flow
The selected unit is displayed in the measurement view.
Use the remote operation to set the associated unit for the "Customized characteristic curve"
application.
