Sensor ADC Error

Bad component on the sensor board

11.3.9

 

 

 

Sensor RTD Out of Range

RTD is improperly wired or has failed

11.3.10

 

 

 

11.3.1 Main Board CPU, Main Board Factory Data, and Main Board User Data Errors.

These error messages mean the main board software is corrupted or the eeprom data on the main board is corrupted.

1.Cycle the power off then on.

2.If cycling the power does not help, call the factory. The main board must be replaced. To do this, the analyzer must be returned to the factory.

3.If cycling the power does not help and the fault message was Main Board User Data, reset the analyzer to factory default. See section 7.8. Re-enter user settings and repeat calibration.

11.3.2 Hardware Error.

Hardware error means there is a missing or bad hardware component on the sensor board. The board must be replaced.

11.3.3Sensor Board Unknown, Sensor Board HW (Hardware) or SW (Software) Mismatch, or Sensor Board Not Communicating.

These error messages mean the main board either does not recognize the sensor board or the sensor board and main board are no longer communicating.

1.Verify that the ribbon cable connecting the main board (on the inside of the front panel) and the sensor board are properly seated. Inspect the connecting cable for obvious tears or breaks.

2.If the ribbon cable is properly seated and appears undamaged, the sensor board should be replaced.
