7. Troubleshooting 

7.1. 

Overview 

Troubleshooting involves responding to error messages, primarily displayed by the MC Toolkit. Error 
messages that may occur on the Transmitter’s local display are fairly self-explanatory and intuitive. 
However, this section covers the diagnostic messages that indicate critical conditions. Other than the 
critical conditions, additional detail is not provided. If you require assistance, contact your distributor 
or Honeywell Technical Support. All other messages are covered by the MC Toolkit Users’ Manual. 

7.2. 

Critical Diagnostics Screens 

 
When a Critical Diagnostic is present in the Transmitter, the Display will display the message 
CRITICAL FAULT on the top line of the LCD and the appropriate diagnostic text on the lower line. 

7.2.1.  Fault Conditions and Recommended Corrective Actions

A critical failure has 
been detected on the 
HART Electronics 
Module. 

Use a HART communicator to read the 
detailed status information from the 
transmitter. Refer to the appropriate 
communicator manual for more 
information about the possible failure 
causes. 

Cycle power to the

If the problem continues to 
occur replace the Electronics

Temperature Sensor 
Module Fault.  
A critical failure has 
been detected on the 
Temperature Sensor 
Module. 

Use a HART communicator to read the 
detailed status information from the 
transmitter. Refer to the appropriate 
communicator manual for more 
information about the possible failure 
causes.   

If the diagnostic status 
indicates an input problem 
(burnout, out of range, etc.), 
correct the root error and then 
cycle power to the transmitter.  
If the problem continues to 
occur replace the 
Temperature Sensor Module.   

Temperature Sensor 
Comm Fault.  
Cannot communicate 
with the Temperature

information about the possible failure 
causes.
