D PV Range Exceeds Sensor Range— active if the Primary Variable (PV) Range has exceeded the range of the sensor's
current calibration. The PV is still accurate but could move out of sensor range.
D PV Exceeds Primary Range— active if the The Primary Variable (PV) has exceeded the PV Range.
D Calibration Validity— active if a vital calibration parameter has been changed.
Rate Limit
D Displacer Rise Rate Exceeded— active if the device detected a rise rate that exceeded the Rapid Rate Limit.
D Displacer Fall Rate Exceeded Alert— active if the device detected a fall rate that exceeded the Rapid Rate Limit.
RTD Sensor
D RTD Sensor—active if the RTD readings are out of range or the RTD is incorrectly connected.
D RTD Open—active if the RTD is not connected.
Sensor Board
D Instrument Temperature Sensor— active if the electronic sensor readings are out of range.
D Sensor Board Processor— active if the device cannot communicate properly or other electronic problem is effecting
the processor.
D Hall Sensor— active if the Hall Sensor readings are out of range.
Temperature Limit
D Instrument Temperature High— active if the device has exceeded the Instrument Temperature High Limit.
D Instrument Temperature Low— active if the device has exceeded the Instrument Temperature Low Limit.
Input Compensation Error
D Temperature Input Error— active if the AO temperature status or RTD status has become “Bad" or “Uncertain" or the
device is not set up correctly to receive AO temperature.
D Upper Fluid Input Error— active if the Upper Fluid AO status has become “Bad" or “Uncertain" or the device is not
setup correctly to receive AO density for the Upper Fluid.
D Lower Fluid Input Error— active if the Lower Fluid AO status has become “Bad" or “Uncertain" or the device is not
setup correctly to receive AO density for the Lower Fluid.
D Fluid Values Crossed— active if the process fluid density values have crossed. The Upper Fluid density has become
greater than the Lower Fluid density.
D Invalid Custom Table— active if the custom process fluid density table being used for temperature compensation is
invalid.
D Temperature Out of Compensation Range—active if the Compensation Temperature has exceeded the
compensation limits.
