System Faults
Table 3-7 lists the system faults that can be displayed.
When one or more system faults occur, the system fault alert
(red light and beeper in cab) turns on to warn the operator
(Figure 3-39
). At the same time, the system fault display
immediately appears and automatically scrolls through the
names of the faults, stopping at each for approximately three
seconds.
The system fault alert turns off when the cause of each fault
is corrected. The name of each fault that has occurred during
operation is retained in memory, however, until the following
two things happen:
• The name of the fault appears on the display at least
once.
• The cause of the fault is corrected.
For this reason, it is normal for the names of faults to appear
when you scroll to the system fault group, even when the
system fault alert is off.
To erase the names of inactive faults, scroll to the system
fault group. Wait until the display scrolls through the name of
each fault. The names of inactive faults will be erased
automatically. If the alert is on, only the names of active faults
will remain.
NO FAULT appears on the display when there are no faults
(
Figure 3-40).
