If all alarms were cleared, the Pretrip Test display
appears (Figure 80).
Figure 80: 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 81 the unit is in the Running Pretrip and is
performing Test 21 of 26, Cool Test.
Figure 81: Cool Test
When all tests are complete, the results are
reported as PASS, CHECK or FAIL (Figure 82).
If the results are CHECK or FAIL, the
accompanying alarm codes will direct the
technician to the cause of the problem.
Figure 82: Pretrip Pass
If the Pretrip Test results are CHECK or FAIL the
problem should be diagnosed and corrected by a
Thermo King service technician before the unit is
released for service.
