Alarm
Message Possible Cause Action
Converter Temp temp Check component power status.
High temp Check set point.
Alarm 81 i –
Cooler Temp
Cooler temp does not
match setting Check Cooler fan/clean filter.
Alarm - Dilution
Pressure Low pressure - leak Perform a leak test.
High pressure Check dilution pressure set point.
Alarm - Eductor
Pressure Low pressure - leak Perform a leak test.
Check component power status.
High pressure Check eductor pressure set point.
Alarm - Flow Flow low Check 80 i and 83 i critical orifices.
Make sure the sample particulate filter in the 83 i
is not blocked. Disconnect lines from the sample
bulkheads, if flow increases, replace the filter.
Alarm - Intensity Low - lamp is failing Replace lamp.
Alarm - Internal

Low pressure –
system leak Perform a leak test.
High pressure –
blocked orifice Check orifice.
Alarm - Pressure High pressure
indication Remove line from pressure transducer. The
pressure reading should go to ambient. Calibrate
the pressure transducer, if necessary.
Check input of external pump with vacuum gauge
and repair or replace pump as necessary.
Deadheaded vacuum should be approx. 12 mmHg.
For pump repair, refer to the pump manual.
Check flow system for leaks.

Manual.”
Alarm - Probe
Temp Low or at ambient
temp Check set point.
