Additional tests

If no clear cause of the error can be identified or the source of the problem can be both the
device and the application, the following additional tests can be performed:
1. Reset the device to the factory setting.
2. Check the digital point level or sensor frequency (display, HART, .. ).
3. Check that the device concerned is functioning correctly. If the digital value does not
correspond to the anticipated point level or sensor frequency, replace the device.
4. Switch on simulation and check the current output. Replace the main electronics if
the current output does not correspond to the simulated value.
11.1.4

Behavior of current output in the event of a fault

The behavior of the current output in the event of faults is defined by the Failure behavior
current output parameter.
Parameter overview with brief description
Description
Defines which current the output assumes in the case of an
error.
Min: < 3.6 mA
Max: >21.5 mA
Enter current output value in alarm condition.
