NOTICE
AL26 is active when all of the sensors are not responding. Check the connector at the back of the
controller; if it is loose or unplugged, reconnect it, then run a Pre-trip test (P5) to clear AL26.
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 diagnostics should not be performed with critical temperature cargoes in the con-
tainer.
CAUTION
!
When PRE-TRIP key is pressed, economy, dehumidification and bulb mode will be deactivated.
At the completion of Pre-trip activity, economy, dehumidification and bulb mode must be reac-
tivated.
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.
A detailed description of the Pre-trip tests and test codes is provided in Table 4–4 . Detailed operating instructions
are provided in Section 5.8 .
