4.7 Pre-Trip Diagnostics
Pre-trip Diagnostics is an independent controller function that suspends normal refrigeration controller activities
and provides preprogrammed test routines. The test routine can be run in Auto Mode, which automatically per

forms a pre programmed sequence of tests, or Manual Mode, which allows the operator to select and run any of
the individual tests.
CAUTION
!
Pre-trip inspection should not be performed with critical temperature cargoes in the container.
CAUTION
!
When the Pre-trip key is pressed economy, dehumidification and bulb mode will be deacti
-
vated. At the completion of the Pre-trip test, economy, dehumidification and bulb mode must
be reactivated.
A Pre-trip test may be initiated by use of the keypad or via communication, but when initiated by communication the
controller will execute the entire battery of tests (auto mode).
At the end of a Pre-trip test, the message “P,” “rSLts” (pretest results) will be displayed. Pressing ENTER will allow
the user to see the results for each of the sub-tests. The results will be displayed as “PASS” or “FAIL” for each test
run to completion.
