8.2.6 Indication of faults related to the
transmission path to the CIE (option with
requirements)
The VACIE may have provision for an indication of
faults related to the transmission path to the CIE.

the transmission path to the CIE shall be
indicated by means of a separate light emitting
indicator and/or an alphanumeric display.

logging application. The faults are also
reported through the general fault
warning indication.
