List of maintenance requests

FIDAMAT 6 gas analyzer
Operating manual –A5E00222135-01
Should there be indications of changes to parameters within the unit,
"maintenance request" will appear on the status line of the display. At the
time of their occurrence, changes of this kind will not affect the measuring
capability of the unit. But to guarantee long-term measuring capability,
remedial measures may need to be taken.
If the relay output of the unit has been configured correspondingly (see
also "Calibration" on page 5-11), signaling to the outside may also take
place.
Defects in the hardware or changes in unit parameters which render the
unit unserviceable for measurement purposes will cause a fault message
to be generated. "Fault" then appears on the status line, provided the unit
is in measurement mode. The measured value flashes and remedial
measures must be taken without fail.
As with the maintenance request, there can be signaling to the outside via
the relay output (function 71). In addition the analog output can be linked
to the output current range which was set using function 77 (measured
value memory).
In addition to maintenance requests and fault messages, other important
messages are recorded in the logbook.
LIM 1-4 Limit values (measuring range 1-4) have been
exceeded / fallen below
CTRL Functional check (see "Diagnosis" on page 5-10)
With the FIDAMAT 6 the following messages entail a maintenance
request (screen display) and are signaled to the outside provided a
corresponding relay has been configured via function 71.
Each maintenance request can be switched off (deactivated) with the aid
of function 87.
