Different error cases can be detected by the On-Board-Diagnostics (OBD) and reported
to the microcontroller. The OBD is useful only when the clamping function is enabled. It
is important to set the clamping threshold values inside the error voltage values shown
in
output voltages and error signals.
7.1
The output signals error conditions, if
• inside the ratings specified in
• outside the range specified in

In the case of interrupted supply lines, the data acquisition device can alert the user. If
two sensors are placed in parallel, the output of the remaining working sensor may be
still used for an emergency operation.
