Chapter 4. Error Codes and Troubleshooting
4.1 Introduction
The XMT1000 flow transmitter is a reliable, easy to maintain instrument. When properly installed and
operated, as described in Chapter: Installation, the meter provides accurate flow rate measurements with
minimal user intervention. However, if a problem should arise with the electronics enclosure or transducers,
this chapter explains how to troubleshoot the XMT1000 flow meter. Indications of a possible problem
include:
• Display of an error message on the LCD screen, Vitality PC software, or HART
• Erratic flow readings
• Readings of doubtful accuracy (e.g., readings that are not consistent with readings from another flow
measuring device connected to the same process).
If any of the above conditions occur, proceed with the instructions presented in this chapter.
Note: For high electrical noise areas, it is recommended that you use the CE Installation methods in
Appendix B.
4.2 Error Classification and Error Codes
The XMT1000 electronics includes two or more subsystems. The Transmitter, Flow Measurement unit and/or
Option I/O. The purpose of the Error codes and string is to convey to the operator about the issues in the
specific subsystem. The communication error indicates that the Transmitter subsystem has lost
communication with Flow measurement sub-system or the Option I/O sub-system.
Errors in XMT1000 are classified into 5 types as indicated in the table below:
If a problem occurs with the electronics or transducers, a built-in error code message system greatly
simplifies the troubleshooting process.
