Error messages via HMI display and HART signal

In case of transmitter errors or malfunctioning, the HART signal (via DTM, EDDL) and HMI are capable of displaying specific error /
fault messages to aid the user in identifying the problem and resolving it In the case of an alarm, a message consisting of an icon
and text displays at the bottom of the process display Use the (1) key to call up the information level Use the "Diagnostics" menu
to bring up the error description with the corresponding help text In the error description, the error number is displayed in the
second line (M028 018) Two further lines are used to describe the error The device status is divided into four groups The message
text beside the icon in the display provides information about where to look for the error There are five areas: Electronics, Sensor,
Configuration, Operating and Process
Icon Description
Error / failure
Functional check (for example, during simulation)
Out of specification
Maintenance required

Error states and alarms

The following represents the errors states / alarms the LMT Series transmitters can encounter along with the recovery action
needed to correct the issue
Error Message Tx LCD Message
F218.023 Electronics NV Failure
F226.044 Current Output
Failure
F228.039 Primary Current
Uncertain
F244.003 Safety Function Flow

F248.006 Self-test failure
C138.036 Data Simulation
Warning
C139.037 Alarm Simulation
Warning
Possible Cause
Electronics memory is
corrupted
The output circuit could be
broken or not correctly
calibrated
The D to A converter is not
properly calibrated or
trimmed
The device is not properly
configured
Calculation of safety function
did not occur in the proper
sequence
Electronics memory test failed
Process data memory check
failed (dynamic duplicated
error)
Program memory test failed
The Level Value produced in
output is derived by the value
simulated in input
An alarm condition is being
simulated by the device
Suggested Action
The electronics must be replaced
A DAC (digital to output converter) trimming
should be performed and if the error persists the
communication board must be replaced
A DAC (digital to output converter) trimming
should be performed and if the error persists the
communication board must be replaced
Check the device configuration
Restart the device If the condition persists
contact service for a replacement
Restart the device If the condition persists
contact service for a replacement
Restart the device If the condition persists
contact service for a replacement
Restart the device If the condition persists

Using a HART configurator (DTM - Hand held)
place device back in normal operating mode
