Rosemount Models 3144 and 3244MV Smart Temperature Transmitters
6-10
OFLOW
The location of the decimal point, as configured in the meter setup, is
not compatible with the value to be displayed by the meter. For
example, if the meter is measuring a process temperature greater than
9.9999 degrees, and the meter decimal point is set to 4 digit precision,
the meter will display an “OFLOW” message because it is only capable
of displaying a maximum value of 9.9999 when set to 4 digit precision.
HOT BU
Hot Backup is enabled and Sensor 1 has failed. This message is
displayed on the
Process Variable
line and is always accompanied by a
more descriptive message on the
Process Variable Unit
line. In the case
of a Sensor 1 failure with Hot Backup enabled, for example, the
Process
Variable
line displays “HOT BU,” and the
Process Variable Unit
line
alternates between “SNSR 1” and “FAIL.”

WARN DRIFT
➜
WARN ALERT
Drift Alert warning is enabled and the difference between Sensor 1 and
Sensor 2 has exceeded the user-specified limit. One of the sensors may
be malfunctioning. The
Process Variable
line displayes “WARN” and the
Process Variable Unit
line alternates between “DRIFT” and “ALERT.”

ALARM DRIFT
➜
ALARM ALERT
The analog output is in alarm. Drift Alert alarm is enabled and the
difference between Sensor 1 and Sensor 2 has exceeded the
user-specified limit. The transmitter is still operating, but one of the
sensors may be malfunctioning. The
Process Variable
line displays
“ALARM” and the
Process Variable Unit
line alternates between
“DRIFT” and “ALERT.”
