If all alarms were cleared, the Pretrip Test display appears
(Figure 84).
Figure 84: Pretrip Test
•
The top line of the display indicates the unit is performing
the non-running portion of the Pretrip Test.
•
The second line measures test progress. The number of
tests completed of the total number of tests to be
performed is shown. In the example above the unit is
performing Test 1 of 26, Sensor Check.
•
The soft keys may be used during the Pretrip Test to select
the Hourmeter, Gauge or Sensor menus.
•
To stop a Pretrip Test at any time turn the unit off. This
will generate Alarm Code 28 Pretrip Abort. Other alarm
codes may also be generated. This is normal when the
Pretrip Test is halted before completion.
When the non-running tests are complete the unit will start
automatically and continue with the Running Pretrip Test. In
the example shown in Figure 85 the unit is in the Running
Pretrip and is performing Test 21 of 26, Cool Test.

When all tests are complete, the results are reported as PASS,
CHECK or FAIL (Figure 86). If the results are CHECK or
FAIL, the accompanying alarm codes will direct the technician
to the cause of the problem.
