i. Unit Pre-Trip Diagnostics.
Pre-trip diagnostics is an independent controller function that will suspend normal refrigeration
controller activities and provide preprogrammed test routines. The test routines include Auto
Mode testing, which automatically performs a pre-programmed sequence of tests or Manual
Mode testing, 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.
Testing may be initiated by use of the keypad. At the end of a pre-trip test, the message “P,”
“rSLts” (pretest results) will be displayed. Pressing the ENTER key will allow the user to see the
results for all subtests. The results will be displayed as “PASS” or “FAIL” for all the tests run to
completion. A detailed description of the pre-trip tests and test codes is provided in Table 2-7.
Detailed operating instructions are provided in section 2-15.
