STG 2 DISCHARGE RTD FAILURE
The stage two discharge RTD is the temperature
probe in the stage two discharge piping. The
control will log this message if it fails to receive a
valid signal from this probe.
STG 2 INPUT TEMP FAILURE
The stage two input RTD is the temperature probe
in the stage two compressor airend intake. The
control will log this message if it fails to receive a
valid signal from this probe.
STG 1 DISCHARGE RTD FAILURE
The stage one discharge RTD is the temperature
probe in the discharge tubing of the first stage
airend. The control will log this message if it fails
to receive a valid signal from this probe.
PKG TRANSDUCER FAILURE
The line transducer is the pressure sensor located
downstream of the aftercooler. The control will
log this message if it fails to receive a valid signal
from this sensor.
STG 2 TRANSDUCER FAILURE
The stage two pressure transducer is the pressure
sensor located in the piping exiting the second
stage airend. The control will log this message if
it fails to receive a valid signal from this sensor.
STG 1 DIS TRANSDUCER FAILURE
The stage one pressure transducer is the pressure
sensor located in the piping exiting the first stage
airend. The control will log this message if it fails
to receive a valid signal from this sensor.
FLUID TRANSDUCER FAILURE
The fluid transducer is the pressure sensor located
in fluid line feeding the airend bearings. The
control will log this message if it fails to receive a
valid signal from this sensor.
AIR FILTER CLOGGED
There is a vacuum switch downstream of the air
filter element that is used to determine the
differential pressure across the filter element. A
high differential pressure indicates a dirty filter
element. If this condition is detected, the control
will log the event. This will not shut down the
compressor, but it can be useful in troubleshooting.
