Alarm / Message
The instrument is equipped with an alarm relay output for signalling
faults. The events which mean a fault at the instrument or are in-
tended to trigger a message, can either trigger an alarm "A" (continu-
ous contact) or a message "M" (2-second impulse).
The faults are recorded and stored in the error history if the event has
been programmed as an alarm or message. For example, if a low
indicator level has not been programmed as an ALARM/MESSAGE,
it is not registered in the error history. Up to 20 error messages can
be stored. A list of these errors can be opened in the information
menu. The information stored per event is the time (day, month, year
and hour) and the type of the error.
