c. Install new chart making sure chart is under the four
corner tabs. Lower the stylus until it has made contact
with the chart. Close and secure door.
DataCORDER
a. Check and, if required, set the DataCORDER Config-
uration in accordance with desired recording parame-
ter. Refer to paragraph 3.6.3.
b. Enter a “T rip Start”. To enter a “trip Start”, do the fol-
lowing:
1. Depress the ALT MODE key and scroll to Code
dC30.
2. Depress and hold the ENTER key for five seconds.
3. The “Trip Start” event will be entered in the Data-
CORDER.
4.7.4 Complete Inspection
Allow unit to run for 5 minutes to stabilize conditions and
perform a pre--trip diagnosis in accordance with the
following paragraph.
4.8 PRE -TRIP DIAGNOSIS
CAUTION
Pre-trip inspection should not be per-
formed with critical temperature cargoes in
the container.
CAUTION
When Pre-Trip key is pressed, economy, de-
humidification and bulb mode will be deac-
tivated. At the completion of Pre-T rip activi-
ty, economy, dehumidification and bulb
mode must be reactivated.
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 3-7, page 3-20. 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.
To start a pre--trip test, do the following:
NOTE
1. Prior to starting tests, verify that unit
voltage (Function Code Cd 07) is within
tolerance and unit amperage draw
(Function Codes Cd04, Cd05, Cd06) are
within expected limits. Otherwise, tests
may fail incorrectly.
2. All alarms must be rectified and cleared
before starting tests.
3. Pre-trip may also be initiated via
communications. The operation is the
same as for the key pad initiation described
below except that should a test fail, the
pre-trip mode will automatically terminate.
When initiated via communications, a test
may not be interrupted with an arrow key,
but the pre-trip mode can be terminated
with the PRE-TRIP key.
a. Press the PRE-TRIP key. This accesses a test selec-
tion menu.
b. TO RUN AN AUTOMATIC TEST: Scroll through the
selections by pressing the UP ARROW or DOWN
ARROW keys to display AUTO, AUTO 1, AUTO 2 or
AUTO 3 as desired and then press the AUTO key.
1. 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.
2. While tests are running, “P#-#” will appear on the left
display, where the #’s indicate the test number and
sub-test. The right display will show a countdown time
in minutes and seconds, indicating how much time
there is left remaining in the test.
CAUTION
When a failure occurs during automatic
testing the unit will suspend operation
awaiting operator intervention.
When an automatic test fails, it will be repeated once .
A repeated test failure will cause “FAIL” to be shown
on the right display, with the corresponding test num-
ber to the left. The user may then press the DOWN
ARROW to repeat the test, the UP ARROW to skip to
the next test or the PRE--TRIP key to terminate test-
ing. The unit will wait indefinitely, until the user manu-
ally enters a command.
CAUTION
When Pre--Trip test Auto 2 runs to comple-
tion without being interrupted, the unit will
terminate pre-trip and display “Auto 2”
“end.” The unit will suspend operation until
the user depresses the ENTER key!
When an Auto 1 runs to completion without a failure,
the unit will exit the pre-trip mode, and return to nor-
mal control operation. However, dehumidification and
bulb mode must be reactivated manually if required.
