LIST key. This accesses the Alarm List Display Mode,
which displays any alarms archived in the Alarm
Queue.
b. The alarm queue stores up to 16 alarms in the se-
quence in which they occurred. The user may scroll
through the list by depressing an ARROW key.
c. The left display will show “AL##,” where ## is the
alarm number sequentially in the queue.
d. The right display will show the actual alarm code.
“AA##” will display for an active alarm, where “##” is
the alarm code. Or “IA##” will display for an inactive
alarm (refer to Table 3-6, page 3--18).
e. “END” is displayed to indicate the end of the alarm list
if any alarms are active.
f. “CLEAr” is displayed if all alarms are inactive. The
alarm queue may than be cleared by pressing the EN-
TER key. The alarm list will clear and “-- -- -- -- -- ” will
be displayed.
NOTE
AL26 is active when all of the sensors are not re-
sponding. Check the connector at the back of the
controller , if it is loose or unplugged, reconnect it.
Then run a pretrip test (P5) to clear AL26.
3.5 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 preforms a pre programmed sequenced
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 per-
formed with critical temperature cargoes in
the container.
CAUTION
When Pre-Trip key is pressed, dehumidifi-
cation and bulb mode will be deactivated.
At the completion of Pre-Trip activity, dehu-
midification and bulb mode must be reacti-
vated.
Testing 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 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 3-9, page 3--21. Detailed operating
instructions are provided in paragraph 4.8.
3.6 DataCORDER
3.6.1 Description
The Carrier T ransicold “DataCORDER” software is
integrated into the controller and serves to eliminate the
temperature recorder and paper chart. The
DataCORDER functions may be accessed by keypad
selections and viewed on the display module. The unit is
also fitted with interrogation connections (see
Figure 3-1), which may be used with the Carrier
T ransicold Data Reader to download data. A personal
computer with Carrier T ransicold Data View software
may also be used to download data and configure
settings. The DataCORDER consists of:
S Configuration Software
S Operational Software
S Data Storage Memory
S Battery Low (Battery Pack)
S Real--T ime Clock (with internal battery backup)
S Six thermistor inputs
S Interrogation Connections
S Power Supply (battery pack)
The DataCORDER performs the following functions:
a. Logs data at 15, 30, 60 or 120 minute intervals and
stores two years’ of data (based on one hour interval).
b. Records and displays alarms on the display module.
c. Records results of pre-trip testing.
d. Records DataCORDER and temperature control
software generated data and events as follows:
S Container ID Change
S Software Upgrades
S Alarm Activity
S Battery Low (Battery Pack)
S Data Retrieval
S Defrost Start and End
S Dehumidification Start and End
S Power Loss (w/wo battery pack)
S Power Up (w/wo battery pack)
S Remote Probe Temperatures in the Container
(USDA cold treatment and cargo probe recording)
S Return Air Temperature
S Set Point Change
S Supply Air Temperature
S Real T ime Clock Battery (Internal Battery)

S Trip Start
S ISO Trip Header (When entered via Interrogation
program)
S Economy Mode Start and End
S “Auto 2” Pre-Trip Start and End
S Bulb Mode Start
S Bulb Mode changes
S Bulb Mode End
S USDA Trip Comment
S Humidification Start and End

3.6.2 DataCORDER Software
The DataCORDER Software is subdivided into the
configuration software, operational software and the
Data Memory.
