Section VIII - Power$ync II™ Operation

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 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 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 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.

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.

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.

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.

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.
