4.7 System Faults
Faults that are detected by the Main CPU can be viewed on the Main CPU LCD interface by navigating
to the "Fault Log" menu, "View Fault Log". The lists of possible faults detected by the Main CPU are
listed in section 6, Main CPU Faults. By pressing the "ENTER" button on the Main CPU LCD interface
when the particular fault is being displayed, the interface will display detailed information for that fault in
the same format as the Elevator Status Screens.
In general, when a fault occurs, the system records the state of 168 bytes of data and stores the data in
two different buffers, the normal and long-term fault buffers. The normal fault buffers can hold the last
50 faults that occurred, and the long-term fault buffer holds the last 350 faults that occurred. The data
in the normal fault buffer is accessed from the “Fault Log” menu. The long-term fault buffer can be
copied to the SD Card and viewed from a PC using a text editor such as Word Pad.
