ambient low flow limit or greater than ambient high flow limit. This error indicates that the
airflow needs to be adjusted according to the procedure “Adjusting the Ambient Airflow.”
· GEN FLO=N.N LPM a flashing airflow indicates that the airflow indicated is less than the
generator low flow limit or greater than generator high flow limit. This error indicates that
the airflow needs to be adjusted according to the procedure “Adjusting the Generator
Airflow.”
· LEAKING SAMPLE LINE indicates that the sample line running from the inlet manifold to
the cloud chamber may be leaking.
· BAD SOLENOID (AMB) indicates that the intake manifold solenoid that controls the
ambient air intake has failed.
· BAD SOLENOID (GEN) indicates that the intake manifold solenoid that controls the
generator air intake has failed.
· FILL WATER BOTTLE indicates that the water bottle is empty.
· CONTINUE FILLING? Indicates that the humidifier is using an unusually large quantity of
water. It may indicate that the water level sensor has failed. Press ENTER to continue
filling.
Alternating Operation
· When the GCM-A is in alternating operation, it will monitor the particulate level but it will
not generate any alarms or warnings.
· The SYSTEM TROUBLE LED will be illuminated whenever the GCM-A is in this mode of
operation.
· The GCM-A monitors the flow rate with a flow sensor. It monitors the particulate level
with a cloud chamber detector.
· The GCM-A will display the particulate level of the generator and ambient air on the LED
bar graphs. The particulate level of the generator and ambient air are also available
through two four- to 20-milliamp (4-20 mA) outputs.
· The particulate level of the generator and ambient air is updated once every 32 seconds.
Ambient Only Operation
· When the GCM-A is in ambient only operation, it will monitor the ambient particulate level,
but it will not generate any alarms or warnings.
· The SYSTEM TROUBLE LED will be illuminated whenever the GCM-A is in this mode of
operation.
• The GCM-A monitors the flow rate with a flow sensor. It monitors the particulate level
with a cloud chamber detector.
· The GCM-A will display the particulate level of the ambient air on the LED bar graph
labeled “AMB”; the bar graph labeled GEN will read zero. The particulate level of the
generator air will not be checked. The particulate level of the ambient air is also
