
Check for the correct connection of the sensor
according to the Electrical Schematic.

If multiples sensor failure alarms are present, it is
possible a sensor is shorting the DC voltage of the
controller. Troubleshoot to isolate the sensor.

To check a thermistor, perform a quick check
according to section P6 Analog Temp Sensor
Inputs.

*Remember 4ATT can be used to troubleshoot
other thermistors

Check connectors per Quick Disconnect
Plugs/Connector section of this manual.

If a Dryer/TAS sensor failure is active, ensure the
machine has the option installed.

If the remote pressure set point is set to ON and a
sensor failure is reported for the remote pressure
signal, the controller shall revert to using the
package discharge pressure sensor for load and
unload sequence control and revert to displaying
the package discharge pressure on the home page
gauge (troubleshoot the remote pressure sensor).

To ensure pressure sensor reading is accurate
connect a manual gauge to compare actual
pressure.
