Status alerts, causes, and recommendations (continued)Table 14-2:
Alert number Alert title Possible causes Recommended actions
A014 Transmitter
Failure
Many possible causes. • Ensure that all wiring compartment covers are in-
stalled correctly.
• Ensure that all transmitter wiring meets specifica-
tions and that all cable shields are properly termi-
nated.
• Check the grounding of all components. See
Section 14.3.
• Evaluate the environment for sources of high elec-
tromagnetic interference (EMI) and relocate the
transmitter or wiring as necessary.
• Contact Micro Motion.
A016 Sensor Temper-
ature (RTD)
Failure
The value computed for the
resistance of the line RTD is
outside limits.
• Check your process against the values reported by
the device.
• Contact Micro Motion.
A020 Calibration Fac-
tors Missing
Some calibration factors
have not been entered or
are incorrect.
• Verify all of the characterization or calibration pa-
rameters. See the sensor tag or the calibration
sheet for your meter.
• Perform site calibration procedures.
A021 Transmitter/
Sensor/Soft-
ware Mismatch
The configured board type
does not match the physical
board.
• Verify all of the characterization or calibration pa-
rameters. See the sensor tag or the calibration
sheet for your meter.
• Ensure that the correct board is installed.
A029 Internal Elec-
tronics Failure
This can indicate a loss of
communication between
the transmitter and the dis-
play module.
• Cycle power to the meter.
• Replace the display module.
• Contact Micro Motion.
A030 Incorrect Board
Type
The loaded software is not
compatible with the pro-
grammed board type.
• Contact Micro Motion.
A033 Insufficient
Pickoff Signal
The signal from the sensor
pickoff(s) is insufficient. This
suggests that the sensor
tubes or vibrating elements
are not vibrating. This alert
often occurs in conjunction
with Alert 102.
• Check for foreign material in the process gas or
fluid, coating, or other process problems.
• Check for fluid separation by monitoring the den-
sity value and comparing the results against ex-
pected density values.
• Ensure that the sensor orientation is appropriate
for your application. Settling from a two-phase or
three-phase fluid can cause this alert.
A037 Sensor Check
Failed
Known Density Verification
failed.
• Check the subtest results and perform the recom-
mended actions.
• Retry the test.
• Contact Micro Motion.
A038 Time Period
Signal Out of
Range
The time period signal is
outside the limits for the
sensor type.
• Check your process conditions against the values
reported by the device.
