Figure 4-1Fault History Screen

The Fault History Screen provides historical data about the operation of the SMART TOUCH controls.. Click on the Fault history button along the top of the Main Screen window (FIG. 1-1), and then click on Read from Control in the pull-down menu. After uploading data from the selected program, a window will appear with the status of numerous counters and lists of the most recent events (see FIG. 4-1 above). Included are details of the control board serial number, software version, default parameters, production date, and last service date. The number of times various faults have occurred is also shown. The last 10 faults are listed, as well as the last 10 blockings (a blocking is an event that causes the burner to shut off). In addition, the number of hours the control has operated in various states is shown, as well as the number of successful and failed ignition attempts. Finally, a count of internal checks is shown.

The total number of occurrences of certain faults are also stored in the control and shown on the left side of the screen. The column on the right shows the total occurrences since the control was built. The column on the left shows the total occurrences since the table was reset. Press the Erase table button at the bottom of the window to clear the totals in the column on the left. This will also clear the Last 10 faults and the Last 10 blockings.

Some of this information may be needed by a service technician to diagnose a problem, so provision is made to create a file in which to save this data. Click on Save file, and define a file name and the folder in which to save it. A bitmap can also be saved by clicking on the Bitmap button at the bottom of the Fault History Screen (FIG. 4-1). The bitmap file will be saved to the folder ENCONFLS located below the file in which the SMART TOUCH program resides.
