SOLITRAC 31 • 4 … 20 mA/HART - four-wire
40090-EN-131119
Maintenance: Due to external influences, the instrument function
is limited. The measurement is affected, but the measured value is
still valid. Plan in maintenance for the instrument because a failure is
expected in the near future (e.g. due to buildup).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
The following table shows the error codes and text messages in the
status message "Failure" and provides information on causes as well
as corrective measures.
