Recommended actions
Power to the transmitter must be cycled to clear this alarm.
1. Check that all wiring compartment covers are installed prop-
erly.
2. Check that the wiring connected to the transmitter meets
specifications and that shields are properly terminated.
3. Check that the sensor and transmitter are both grounded
properly.
4. Evaluate the environment for sources of high electromag-
netic interference (EMI) and relocate the transmitter or wir-
ing as necessary.
5. Cycle power to the transmitter.
6. If the problem persists, replace the transmitter.
The flow calibration factor and/or K1 has not been entered since
the last master reset. Verify that all of the characterization pa-
rameters match the data on the sensor tag. If the problem per-
sists:
1. Check that the sensor type (curved or straight) is properly se-
lected.
2. Confirm that no "T-series" calibration parameters have been
set if this is a curved tube sensor.
The sensor is recognized as a straight tube but the K1 value indi-
cates a curved tube, or vice versa. Verify that all of the character-
ization parameters match the data on the sensor tag. If the prob-
lem persists:
1. Check that the sensor type (curved or straight) is properly se-
lected.
2. Confirm that no "T-Series" calibration parameters have been
set if this is a curved tube sensor.
3. If this alarm occurs in conjunction with A006, check the LLC
resistance and for shorts to case
Try cycling power to the meter to see if the alarm clears. If the
alarm persists, replace the core processor.
