and perform a pre-trip diagnosis in accordance with
Section 5.7 .
5.7 PRE-TRIP DIAGNOSTICS
CAUTION
!
Pre-trip inspection should not be per-
formed with critical temperature cargoes
in the container.
CAUTION
!
When Pre − Trip key is pressed, economy,
dehumidification and bulb mode will be
d e a c t i v a t e d . A t t h e c o m p l e t i o n o f
Pre
− Trip activity, economy, dehumidifica-
tion and bulb mode must be reactivated.
Pre-Trip diagnostics provides automatic testing of the
unit components using internal measurements and
comparison logic. The program will provide a “PASS” or
“FAIL” display to indicate test results.
The testing begins with access to a Pre-trip selection
menu. The user may have the option of selecting one
of three automatic tests.
These tests will automatically perform a series of indi-
vidual Pre-trip tests. The user may also scroll down to
select any of the individual tests.
When only the short sequence is configured, it will
appear as “AUtO” in the display. Otherwise “AUtO1”
will indicate the short sequence and “AUtO2” will indi-
cate the long sequence. The test short sequence will
run tests P0 through P6. The long test sequence will
run tests P0 through P10.
A detailed description of the Pre-trip test codes is listed
in Table 4–7 . If no selection is made, the Pre-trip menu
selection process will terminate automatically. How-
ever, dehumidification and bulb mode must be reacti-
vated manually if required.
Scrolling down to the “rSLts” code and pressing
ENTER will allow the user to scroll through the results
of the last pre-trip testing run. If no pre-testing has
been run (or an individual test has not been run) since
the unit was powered up, “ −−−− ” will be displayed.
To start a Pre-trip test, do the following:
NOTE
1. Prior to starting a Pre − trip test, verify that unit volt-
age (Cd07) is within tolerance and unit amperage
draw (Cd04, Cd05, Cd06) are within expected lim-
its. Otherwise, tests may fail incorrectly.
2. All alarms must be rectified and cleared before
starting tests.
3. Pre − trip may also be initiated via communica-
tions. The operation is the same as for the key-
pad initiation described below except that
should a test fail, the Pre
− trip mode will auto-
