Disconnect the electrical power and depressurize the generator before attempting any trouble-
shooting activities according to the shut down steps in the operation section. Only trained per-
sonnel using reasonable care should perform any troubleshooting activities.
Determine whether the trouble is with the compressed air source or the Tri-Gas Generator. First,
check that the compressed air source is delivering. If you have an integrated compressor (Model
LCMS-SF5000), refer to the compressor troubleshooting section, otherwise check that the
compressed air source is delivering a minimum, continuous flow of 180 SLPM (6.3 SCFM) at a
pressure between 110 - 140 PSIG (7.6 - 9.6 barg).
If the compressor air supply is confirmed, then go to the Tri-Gas Generator troubleshooting sec
-
tion, and begin troubleshooting the Tri-Gas Generator.
