5.8 Pre-Trip Diagnosis
CAUTION
!
Pre-trip inspection should not be performed with critical temperature cargoes in the container.
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.
Pre-trip diagnosis 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 two
automatic tests. These tests will automatically perform a series of individual 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 indicate 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 4–6 . If no selection is made, the pre-trip menu
selection process will terminate automatically. However, dehumidification and bulb mode must be reactivated
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.
NOTE
Pre-trip may also be initiated via communications. The operation is the same as for the keypad initia
-
tion described below except that should a test fail, the pre-trip mode will automatically terminate.
When initiated via communications, a pre-trip test may not be interrupted with an Arrow key, but the
pre-trip test can be terminated with the PRE-TRIP key.
5.8.1 Prior to Starting a Pre-Trip
Verify the following conditions prior to starting a pre-trip.
• Unit voltage (Cd07) is within tolerance.
• Unit amperage draw (Cd04, Cd05, Cd06) are within expected limits.
• All alarms are cleared and rectified.
5.8.2 Starting a Pre-Trip
1. Press the PRE-TRIP key to access the pre-trip test selection menu.
2. To Run an Automatic Test: Scroll through the selections by pressing the Up or Down Arrow keys to display
AUTO, AUTO 1, AUTO 2 or AUTO 3 as desired, then press the ENTER key.
• The unit will execute the series of tests without any need for direct user interface. These tests vary in
length, depending on the component under test.
• While tests are running, “P#-#” will appear on the left display; the #’s indicate the test number and sub-
test. The right display will show a countdown time in minutes and seconds, indicating the amount of time
remaining in the test.
When a Pre-trip Auto 1 test runs to completion without a failure, the unit will exit pre-trip mode and return
to normal control operation. However, dehumidification and bulb mode must be reactivated manually if
required.
