The faults, indicated in the table below, are listed in order of priority. The faults on top of the list have
the highest priority. This means that faults with a lower priority can be overwritten by faults of a higher
priority.
At power-on the system is explicitly tested for failures indicated by display messages 1, 2, 3, 4, 5, 6
and 7. During normal operation these tests (except 2) run at the background.
下表中指出的故障系按优先顺序排列。表中上方的故障有最高优先权。这意味着拥有高优先的故障可
以覆盖低优先问题。当接通电源后，系统将明确地检测是否存在故障，此时显示器依次显示信息
1, 2,
3, 4, 5, 6
和
7
。在正常操作情况下，这些测试（
2
除外）将在本底进行。
