Installation related problems

Read Section 2 – Installation to make sure the recorder has been properly installed. Document 51-52-05-01 How to Apply Digital Instrumentation in Severe Electrical Noise Environments can provide additional relevant information.

ATTENTION

System noise induced into the recorder will result in diagnostic error messages recurring.

If the diagnostic error messages can be cleared, it indicates a “soft” failure and is probably noise related.

If system noise is suspected, completely isolate the recorder from all field wiring. Use calibration sources to simulate PV and check all recorder and control functions; that is, pen functions, chart trace, output, alarms, etc.

Application related problems

Review the application of the recorder; then, if necessary, direct your questions to the local sales office.

Hardware and software related problems

Use the troubleshooting error messages and observable symptoms to identify typical failures which may occur in the recorder. Follow the troubleshooting procedures to correct the problems.
