6.8 Status alarms
Status alarms are reported by a PROFIBUS host, the display, and ProLink II software. Remedies for
the alarm states appear in Table 6-4.
Note: Some status alarms will cause all of the function blocks (AI, AO, and totalizer) to change to Out
of Service mode.

code Description Possible remedies
A001 EEPROM checksum Cycle power to the transmitter.
The flowmeter might need service. Contact Micro Motion Customer
Service.
A002 RAM error Cycle power to the transmitter.
The flowmeter might need service. Contact Micro Motion Customer
Service.
A003 Sensor failure Check the test points. See Section 6.12.
Check the sensor coils. See Section 6.14.
Check wiring to sensor. See Section 6.9.2.
Check for slug flow. See Section 6.10.
Check sensor tubes.
A004 Temperature overrange Check the test points. See Section 6.12.
Check the sensor coils. See Section 6.14.
Check wiring to sensor. See Section 6.9.2.
Verify process temperature range is within limits for sensor and
transmitter.
Verify flowmeter characterization. See Section 6.7.4.
Contact Micro Motion Customer Service.
A005 Input overrange Check the test points. See Section 6.12.
Check the sensor coils. See Section 6.14.
Verify process conditions.
Verify that transmitter is configured to use appropriate measurement
units. See Section 4.5.
Verify flowmeter characterization. See Section 6.7.4.
Re-zero the flowmeter. See Section 3.6.
A006 Transmitter not configured Check the characterization. Specifically, verify the FCF and K1
values. See Section 3.3.
Contact Micro Motion Customer Service.
A008 Density overrange Check the test points. See Section 6.12.
Check the sensor coils. See Section 6.14.
Check for air in flow tubes, tubes not filled, foreign material in tubes,
coating in tubes.
Verify characterization. See Section 6.7.4.
A009 Transmitter initializing/warming up Allow the transmitter to warm up. The error should disappear from the
status words once the transmitter is ready for normal operation. If
alarm does not clear, make sure sensor is completely full or
completely empty. Verify sensor configuration and transmitter wiring
to sensor (refer to installation manual).
