MODEL 5081-T SECTION 1.0 DESCRIPTION AND SPECIFICATIONS 1.6 HART COMMUNICATIONS 1.6.1 OvERvIEw OF HART COMMUNICATION HART (highway addressable remote transducer) is a digital communication system in which two frequencies are superimposed on the 4 to 20 mA output signal from the transmitter. A 1200 Hz sine wave represents the digit 1, and a 2400 Hz sine wave represents the digit 0. Because the average value of a sine wave is zero, the digital signal adds no dc component to the analog signal.

MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING 10.1 OvERvIEw The Model 5081-T transmitters automatically monitor for fault conditions. The diagnose Menu allows the current variable settings to be reviewed and shows fault messages indicating problems detected. Figure 10-1 illustrates the relationship between the diagnose Menu and its sub-menus. The mnemonics are defined in Table 10-1. Step 3 10.1.2 DISPLAyING DIAGNOSTIC vALUES 10.1.

MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING 10.2 FAULT CONDITIONS Three classes of error conditions/problems are detected and differentiated between by the diagnostic program. System disabling problems are faults caused by failures in the loop or significant variations in the process. System non-disabling problems are warnings and deal with input or A to d conversion settings. The third class of detected problems are error messages and occur when the calibration limits are exceeded. 10.2.

MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING 10.3 DIAGNOSTIC MESSAGES The Model 5081-T transmitter’s diagnostics constantly monitor the conductivity loop for possible problems. If an operational problem is encountered, check the display for a fault or error message. These are displayed in the Temperature/Current output segment of the display. Note the message and refer to Table 10-2 for a description of possible problems that may have triggered the diagnostic message. TABLE 10-2.

MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING 10.4 QUICK TROUBLESHOOTING GUIDE Table 10-3 identifies some of the more common symptoms and suggests actions to help resolve a problem. In general, wiring is the most common cause. TABLE 10-3. Quick Troubleshooting Guide. SyMPTOM Wrong temperature reading. Suspected temp. compensation problem. ACTION display segments missing. display inoperable. Analyzer locks up; won't respond. Perform a temperature standardization. Verify sensor's RTd.

MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING 10.5 SySTEMATIC TROUBLESHOOTING If the Quick Troubleshooting Guide does not resolve the error, try the step-by-step approach offered in Figure 10-4. Step 1 Follow the troubleshooting flow chart. Step 2 Refer to the tests and instructions indicated by the flow chart to diagnose the problem. NOTE: Before starting this procedure make sure that all wiring is correct.

MODEL 5081-T SECTION 10.0 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 measurements. 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.

MODEL 5081-T 10.8 SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING TROUBLESHOOTING wHEN A FAULT OR wARNING MESSAGE IS SHOwING Message Explanation See Section OuEr rAnGE over range, measurement exceeds display limit 10.8.1 SEnSor FAIL Bad sensor, sensor current is a large negative number 10.8.2 CAL Error Calibration error, sensitivity (nA/ppm) is too high or too low 10.8.3 nEEd 0 CAL Sensor needs re-zeroing, reading is too negative 10.8.4 rtd FAIL Bad temperature reading 10.8.
PAGE 86
MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING 10.8.3 CAL Error At the end of the calibration step, the transmitter calculates the sensitivity in nA/ppm. If the sensitivity is outside the range normally expected, the transmitter displays the CAL Error message and the transmitter does not update the calibration. For assistance, refer to the troubleshooting section specific for the sensor. 10.8.4 nEEd 0 CAL nEEd 0 CAL means that the concentration of the analyte is too negative. 1.

MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING 10.8.7 OFFSEt Err The OFFSEt Err message appears if the zero offset (in mV) exceeds the programmed limit. Before increasing the limit to make the OFFSEt Err message disappear, check the following: 1. Verify that the reference meter is working properly and is properly calibrated. 2. Verify that the process sensor is working. Check its response in a solution of known conductivity. 3.

MODEL 5081-T SECTION 11.0 MAINTENANCE SECTION 11.0 MAINTENANCE 11.1 OvERvIEw 11.3 TRANSMITTER MAINTENANCE Maintenance consists of "Preventative" and "Corrective" measures. Periodically clean the transmitter window with household ammonia or glass cleaner. The detector for the infrared remote controller is located behind the window at the top of the transmitter face. The window in front of the detector must be kept clean. 11.2 PREvENTATIvE MAINTENANCE 11.2.1 Transmitter Maintenance.

MODEL 5081-T SECTION 11.0 MAINTENANCE FIGURE 11-2. Exploded view of Model 5081-T Transmitter Three screws (part 13 in the drawing) hold the three circuit boards in place. Removing the screws allows the display board (part 2) and the CPU board (part 3) to be easily removed. A ribbon cable connects the boards. The cable plugs into the CPU board and is permanently attached to the display board. A 16 pin and socket connector holds the CPU and analog (part 4) boards together.
