Status alarms and recommended actions
Alarm code
Description
Cause
Recommended actions
A003
Sensor failure
Continuity failure of
drive circuit, LPO, or
RPO, or LPO-RPO
mismatch when
driving.
•
Check the drive gain and the pickoff
voltage. See Section 10.25 and Section
10.26 .
•
Check the wiring between the sensor and
transmitter. See Section 10.10.
•
Check for electrical shorts. See Section
10.27 .
•
Check sensor tubes.
A004
Temperature sensor
failure
Combination of A016
and A017
•
Check the sensor wiring. See Section
10.27.1 .
•
Check the wiring between the sensor and
transmitter. See Section 10.10.
•
Verify temperature characterization
parameters (
Temp Cal Factor
).
•
Verify process conditions.
•
Contact Micro Motion.
A005
Input overrange
The measured flow
has exceeded the
maximum flow rate of
the sensor (ΔT greater
than 200 μs)
•
If other alarms are present, resolve those
alarm conditions first. If the current alarm
persists, continue with the recommended
actions.
•
Verify process conditions.
•
Check for slug flow. See Section 10.24.
•
Check the drive gain and the pickoff
voltage. See Section 10.25 and Section
10.26 .
•
Check for electrical shorts. See Section
10.27 .
•
Check sensor tubes.
•
Contact Micro Motion.
