4.5 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 preprogrammed sequence of tests, or Manual Mode, 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.
CAUTION
!
When the PRE TRIP key is pressed, Economy, Dehumidification and Bulb Mode will be deacti
-
vated. At the completion of the pre-trip test, Economy, Dehumidification and Bulb Mode must be
reactivated.
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. Press the ENTER key to
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

4.6 DataCORDER
4.6.1
Description
Carrier Transicold “DataCORDER” software is integrated into the controller and serves to eliminate the tempera
-
ture recorder and paper chart. DataCORDER Software is subdivided into operational software, configuration soft
-
ware, and data memory. DataCORDER functions may be accessed by keypad selections and viewed on the
display module.
For a description of DataCORDER communications, refer to
.
The DataCORDER consists of:
• Configuration software
• Operational software
• Data storage memory
• Real time clock (with internal battery backup)
• Six thermistor inputs
• Interrogation connections
• Power supply (battery pack)
The DataCORDER performs the following functions:
• Logs configured sensor data at the configured time interval.
• Records alarm activity.
• Records PTI results.
• Records modifications to the controller (i.e. configuration, time, software upgrade, etc).
• Records operational events (i.e. defrost, dehumidification, setpoint change, power On/Off, cooling mode, etc).
• Records optional events (i.e. USDA activity, trip start, probe calibration, GDP calibration, XtendFresh opera
-
tion, vent position sensor location, etc).
