PV status Cause - Action
(blank)
• PV is normal – no action required
‘B’
• Possible calibration error – Clear calibration
• (A/B) (I/O) TB cannot execute due to internal firmware state – Attempt cold
restart of device.
• AITB cannot execute due to hardware fault – Replace sensor board
• Sensor failure – Check Connection between Sensor board and meter body.
• Meter body Characterization Data is Bad – Replace meter body
• Meter body A/D Failure – Replace meter body
• Meter body Sensor Fail – Replace meter body
• Configuration is bad – Check possible units and range settings for input type
and correct AITB configuration.
• Hardware fault detected - Replace sensor board
‘U’
• Warning: Calibration (zero or trim) is causing excessive adjustment to
characterization value.
• Warning: Input inaccurate due to uncertain input data integrity.
• Warning: Input inaccurate due to input conversion limitations or resolution.
• Warning: Input outside of characterized range. Value is estimated.
‘F’
• Sensor Failure has occurred or the transmitter was unable to communicate
with the sensor.
• Check the connection between the Sensor and the Main Board of the
