DIAGNOSIS AND TROUBLESHOOTING

10.7 WARNING AND FAULT MESSAGES

The Model 5081-T transmitter continuously monitors the sensor and transmitter for conditions that cause erroneous meas- urements. When a problem occurs, the transmitter displays either a warning or fault message. A warning alerts the user that a potentially disabling condition exists. There is a high probability that the measurement is in error. A fault alerts the user that a disabling condition exists. If a fault message is showing, all measurements should be regarded as erroneous.

When a WARNING condition exists:

1.The main display reading remains stable; it does not flash.

2.A warning message appears alternately with the temperature and output readings in the second line of the display. See Section 10.3 for an explanation of the warning messages and suggested ways of correcting the problem.

When a FAULT exists:

1.The main display reading flashes.

2.The words FAULT and HOLD appear in the main display window.

3.A fault message appears alternately with the temperature and output readings in the second line of the display. See Section 10.3 for an explanation of the fault messages and suggested ways of correcting the problem.

4.The output current will remain at the present value or go to the programmed fault value. See Section 7.2 for details on how to program the current generated during a fault condition.

5.If the transmitter is in HOLD when the fault occurs, the output remains at the programmed hold value. To alert the user that a fault exists, the word FAULT appears in the main display, and the display flashes. A fault or diagnostic message also appears.

6.If the transmitter is simulating an output current when the fault occurs, the transmitter continues to generate the sim- ulated current. To alert the user that a fault exists, the word FAULT appears in the display, and the display flashes.
