3.22.2 LCD display
The LCD displays abbreviated diagnostic messages for troubleshooting the transmitter. To
accommodate two-word messages, the display alternates between the first and second
word. Some diagnostic messages have a higher priority than others, so messages appear
according to priority, with normal operating messages appearing last. Messages on the
Process Variable line refer to general device conditions, while messages on the Process
Variable Unit line refer to specific causes for these conditions. A description of each
diagnostic message follows.

Description
If the meter does not appear to function, make sure the
transmitter is configured for the meter option you desire.
The meter will not function if the LCD display option is set to
Not Used.
This message indicates one of several conditions including:
• The transmitter has experienced an electronics module
failure.
• The transmitter self-test has failed.
• If diagnostics indicate a failure of the electronics
module, replace the electronics module with a new one.
Contact the nearest Emerson Field Service Center if
necessary.
The transmitter has detected an open or shorted sensor
condition. The sensor(s) might be disconnected, connected
improperly, or malfunctioning. Check the sensor
connections and sensor continuity.
The temperature sensed by the transmitter exceeds the
sensor limits for this particular sensor type.
The transmitter operating temperature limits (–40 to 185 °F
[–40 to 85 °C]) have been exceeded.
During a loop test or a 4–20 mA output trim, the analog
output defaults to a fixed value. The Process Variable line of
the display alternates between the amount of current
selected in milliamperes and "WARN." The Process Variable
Unit line toggles between "LOOP," "FIXED," and the amount
of current selected in milliamperes.e
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.
