Troubleshooting Tools

The SMV 3000 transmitter is constantly running internal diagnostics to monitor sensor and transmitter functions. The SCT and SFC, when connected to the SMV control loop, monitor the transmitter functions, and status of the control loop and the communications link.

When a diagnostic failure is detected, a status is generated by the SMV. The SCT or SFC, connected to the SMV control loop, will interpret the transmitter status into messages which can be viewed through the SCT Status tab card or an SFC display. Corrective actions then can be taken to clear transmitter fault conditions.

There are additional diagnostics provided by the STIMV IOP for transmitters integrated with the TPS/TDC control systems and any message will appear in the TRANSMITTER STATUS field of the Detail Display in the Universal Station. Details about the STIMV IOP diagnostic messages are given in the PM/APM Smartline Transmitter Integration Manual PM12-410which is part of the TPS/TDC system bookset and in Appendix A of this manual.

Your primary troubleshooting tool is the SCT in which you can run a status check and refer to the detailed status message table that lists the diagnostic messages and their meanings. Recommended actions are provided to help in correcting transmitter fault conditions. Use the SCT also to verify the transmitter’s configuration data and check to be sure your process is operating correctly.

NOTE: The SFC can also be used to check transmitter status and identify diagnostic messages. If you are using an SFC to check transmitter status and diagnose transmitter faults, refer to the Smart Field Communicator Model STS103 Operating Guide 34-ST-11-14for detailed keystroke information and trouble shooting procedures.
