Acyclic Extended Diagnostics (General Fault Codes)

In addition to the extended diagnostics available by cyclic data exchange (shown above),
further extended diagnostics are available via acyclic communications. This consists of
six bytes. Please see
for the location of the "Extended Diagnostics".
Note:
Certain fault codes (identified by an asterisk [*] in the table below) will persist
until a manual reset has been performed (see

Corrective Action
Check the application and echo
profile to determine optimum
configuration for the application,
to ensure the device can obtain a
measurement.
Cycle the power. If the condition
persists, call the factory.
Check the calibration settings of
the device. Ensure that the
settings for High Calibration Point
and Low Calibration Point are
different.
Return the device to the factory.
Lower the ambient temperature
enough to cool the device.
This fault code will persist until a
manual reset is performed using
PDM or the LCD interface.
