Revision 5.0 ST 800 Series HART/DE Option User’s Manual Page 93
• Meter body failure
• Sensor communication timeout
• Sensor firmware flow failure
Resolution:
Reset the device. If the problem persists, replace
the Meter Body.
Non-Critical
(continued)
No temperature compensation data exists for
analog output calculations. Loop accuracy may
be slightly compromised. Effect will be minor
degradation of ambient temperature influence
specifications.
Resolution:
Replace Electronics Module (PWA) to achieve
the maximum current loop accuracy or return the
device to factory for DAC compensation.
Reset Corrects Flag Successful “Reset Corrects” operation will set
this flag and display message as “Calibration
Correction values are reset to factory default”.
When ‘LRV Correct’ and ‘URV Correct’
operations are performed, the flag will be reset.
• There is a failure on the Sensor Board
• Redundant Characterization Calculation
Error
• Calculated pressure is above Upper
Transducer Limit (UTL).
Resolution:
Check range and, if required, replace transmitter
with one that has a wider range. Meter Body may
have been damaged. Check the transmitter for
accuracy and linearity. Replace Meter Body and
The calculated pressure is above the Upper
Transducer Limit (UTL).
Resolution:
Check range and, if required, replace transmitter
with one that has a wider range. Meter Body may
have been damaged. Check the transmitter for
accuracy and linearity. Replace Meter Body and
Output current is fixed and not varying with
applied input. Output Mode is active.
Resolution:
Exit Output mode if active.
