In the menu item "Current output" you determine the behaviour of the
current output during operation and in case of failure. The following
options are available:
Current output
Characteristics curve 4 … 20 mA
20 … 4 mA
Failure mode 3) Hold value
20.5 mA
22 mA
< 3
.6 mA
Min. current 4) 3 .8 mA
4 mA
Max. current 5) 20 mA
20.5 mA
The values in bold font represent the data of the factory setting.
In HART multidrop mode, the current is constantly 4 mA. This value
does not change even in case of failure.

Output mode: 4-20 mA ▼
Failure mode: 22 mA ▼
Min. current 3.8 mA ▼
The functional safety is already activated Ex factory for instruments
with SIL qualification. For instruments Ex factory without SIL
qualification, the functional safety must be activated by the user for
applications according to SIL via the indicating and adjustment
module. The SIL factory setting cannot be deactivated by the user.
The activation of SIL has the following impact:
3) Value of the current output in case of failure, e.g. if no valid measured value
is delivered.
4) This value is not underrun during operation.
5) This value is not exceeded during operation.
