Functional Test
The monitoring system informs the operator of the
status of the machine systems. The monitoring
syst
em informs the operator of problems or of an
impending problem.
If the a ction al arm does not sound during this test
or
machine monitoring displ ays are not function-
ing, do not operate the machine until the cause
has been corrected. Machine operation with faulty
ac
tion ala rms or displays could result in injury or
death as any Warning Category 3 notifications will
not be re layed to the operator.
When the engine starts the monitoring system runs
a test. The operator must observe the monitoring
s
ystem during the test to determine proper operation.
The s elf testin
g feature verifies that the modules of
the monitoring system are properly operating. The
self testing feature verifies that the display module is
properly oper
ating.
The operator must observe the outputs in order to
determine if
the modules are operating properly. This
self testing feature is three seconds long.
The monitor
ing panel will then return to the normal
operating mode.
Alert Indicators

Illustration 84
Action Lamp (1) – Theactionlampison
the Gauge cluster. If the action lamp is ON,
then attention to service is required.
Reference: See “Warning Categories” for information
on indicated service.
Electrical System (2) – This indicator
indicates a malfunction in the electrical
system. If this alert indicator flashes, the
system voltage is too high or too low for machine
operation.
Increase the engine speed to high idle, if the electrical
loads are high. The electric loads consist of the air
conditioning and/or the lighting. An alternator will
generate more output when the engine is at high idle.
If the alert indicator for the electrical system stops
within one minute, the electrical system is operating
normally. During the periods of low engine speeds,
the alternator is overloaded.
Modify the operating cycle. This will prevent the
electrical system from overloading. This will also
prevent the electrical system from discharging the
batteries. You can also reduce the loads on the
electrical system. Use the medium fan speed in the
cab instead of the high fan speed.
