Warning and Error Messages
The following table gives most of the error and warning messages
contained in the test Hierarchy of the Monitor. There is a description of
each fault as well as the possible cause of each fault. The user must
evaluate the significance of each message.
Warning Messages Description of Fault Possible Cause
AIR FLOW TOO LOW
The air pressure difference
created by the pump in the
pneumatic (airway) system
(tubes and/or analysis cell)
is too low. This means that
the tubing and/or analysis
cell cannot be properly
flushed out and the sample
in the analysis cell is
therefore not necessarily
“new”
1. The length of
the sampling
tube attached to
the Monitor’s
inlet has been
incorrectly
entered.
2. Either the
external or
internal
pneumatic
system is not
air-tight
3. The pump is
defective
4. This might also
indicate a too
high inlet
pressure.
AIRWAY-SYSTEM BLOCKED
The air pressure difference
created by the pump in the
pneumatic ( airway)
system ( tubes and/or
analysis cell) is too high
1. The Air inlet is
blocked.
2. Air Filter DS0759
blocked.
ALARM LIMIT EXCEEDED
The Monitor has measured
a concentration of gas
greater than the alarm
limit concentration entered
NO INDEX MARK FROM FILTER
CAROUSEL
