Figure 94: Programming Test Pretrip Display
The Pretrip Test display appears. The top line of
the display indicates the unit is performing the
non-running Pretrip Test. Test progress is
measured by the number of tests completed out of
a total of 26. In the example below 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.
Figure 95: Selecting Menus
When all tests are complete, the results are
reported as PASS, CHECK or FAIL. If the results
are CHECK or FAIL, the accompanying alarm
codes will direct the technician to the cause of the
problem.
When the non-running test are complete the unit
will start automatically and continue with the
Running Pretrip Test. In the example shown
below the unit is in the Running Pretrip and is
performing Test 21 of 26, Zone 1 Cool test.
Figure 96: Zone 1 Cool Test
If the Pretrip Test results are CHECK or FAIL the
problem should be diagnosed and corrected before
the unit is released for service.
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.

Selecting Diesel or Electric
Operation
The Diesel or Electric Display allows the operator
to manually select diesel mode operation. The unit
can also be programmed to automatically select
electric mode operation when standby power is
available and diesel mode operation if standby
power fails or is removed. If the unit is
programmed to switch automatically from diesel
to electric and electric to diesel these screens do
not appear.
Factory units are programmed to
automatically switch to electric mode when
standby power becomes available. The unit
must be switched to diesel power manually as
programmed from factory.
If the unit has standby power available and is
turned on, the electric standby run screen will
appear after the standard screen. The new mode is
then confirmed for 10 seconds.
