Troubleshooting
Table 5-1. Diagnostic message troubleshooting
LCD Messages Host Diagnostic Message Possible Problems Recommended Actions
AP GP LIMIT Static Pressure Out of Limits The Static Pressure is exceeding the
sensor limits.
Verify process conditions are within the
sensor limits.
BOARD COMM ERROR Feature Board Communication Error The feature board electronics are
experiencing communication
problems. This problem may be
temporary and could clear
automatically.
Cycle power to the device. If the problem
persists, replace the feature board
electronics.
CURR SAT Primary Variable Analog Output
Saturated
The primary variable has exceeded
the range points defined for the 4-20
mA analog output signal. The analog
output is fixed at the high or low
saturation point and is not
representative of the current process
conditions.
Verify the process conditions and modify
the Analog Range Values if necessary.
DP LIMIT Differential Pressure Out of Limits The Differential Pressure is exceeding
the sensor limits.
Verify that the process conditions are within
the sensor limits.
FAIL BOARD ERROR Feature Board Error The feature board electronics have
detected an unrecoverable failure.
Replace the feature board electronics.
FAIL PT ERROR Process Temperature Sensor Failure The process temperature sensor has
failed or is incorrectly wired.
Check the sensor wiring and fix any shorts
or open connections.
If the sensor wiring is correct, check the PT
sensor and replace if necessary. If the
problems persists, replace the feature
board electronics.
FAIL SENSOR ERROR Sensor Module Failure The SuperModule assembly is
providing measurements that may no
longer be valid.
Verify the Sensor Module Temperature is
within the operating limits of the
transmitter. Replace SuperModule
assembly if necessary.
FLOW CONFIG Updating Flow Configuration - Flow
Values Constant
A flow Configuration is currently
being downloaded to the transmitter.
During the download, the flow output
will be fixed at the last calculated
value. Once the download is
complete the transmitter will resume
live calculations.
No action is required. Please wait until the
flow configuration download is complete
before performing other configuration
tasks.
FLOW INCOMP ERROR Energy Invalid for Flow Configuration The Energy Flow variable is not
compatible with the current flow
configuration but is mapped to the
totalizer, a process variable, or a burst
variable.
These discrepancies can be fixed with the
following actions:
Verify configuration for the fluid type
supports Energy Flow calculation.
Do not specify Energy Flow for the
totalizer, process variables or burst
variables unless the transmitter has a
compatible flow configuration.
FLOW INCOMP ERROR Static Pressure Sensor Missing A static pressure sensor is needed for
the current flow configuration.
Download a flow configuration that is
compatible with the sensors equipped in
the device or replace the module with a
model that includes a static pressure
sensor.
FLOW INCOMP ERROR Flow Configuration Download Error The flow configuration did not
successfully download to the
transmitter.
Redownload the flow configuration using
the Engineering Assistant software.
FLOW LIMIT Flow Output Out of Limits The flow output value is exceeding
the flow rate operating limits.
Verify the process conditions, and modify
the flow configuration parameters and
operating ranges as needed.
FLOW LIMIT Energy Flow Out of Limits The energy flow value is exceeding
the flow rate operating limits.
Verify the process conditions, and modify
the flow configuration parameters and
operating ranges as needed.
LCD UPDATE ERROR LCD Update Error The LCD is not receiving updates from
the feature board electronics.
Examine the LCD Connector and reset the
LCD.
If the problem persists, first replace the LCD
then replace the feature board electronics if
necessary.
