Description
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".
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 displays "WARN" and the Process Variable Unit
line alternates between "DRIFT" and "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."
The digital and analog outputs are in alarm. Possible causes
of this condition include, but are not limited to, an
electronics failure or an open sensor. 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, for
example, the Process Variable line displays "ALARM," and
the Process Variable Unit line alternates between "SNSR 1"
and "FAIL."
The transmitter is still operating, but something is not
correct. Possible causes of this condition include, but are
not limited to, an out-of-range sensor, a fixed loop, or an
open sensor condition. In the case of a Sensor 2 failure with
Hot Backup enabled, the Process Variable line displays
"WARN," and the Process Variable Unit line alternates
between "SNSR 2" and "RANGE."
