Testing may be initiated by use of the Key Pad 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--7, page 3--24. detailed operating
instructions are provided in paragraph NO TAG.
3.6 DataCORDER
3.6.1 Description
The Carrier Transicold “DataCORDER” software is
integrated into the controller and serves to eliminate the
temperature
recorder
and
paper
chart.
The
DataCORDER functions may be accessed by key pad
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
Transicold Data Reader to down load data. A personal
computer with Carrier Transicold DataLINE software
may also be used to download data and configure
settings. 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:
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:
Container ID Change
Software Upgrades
Alarm Activity
Battery Low (Battery Pack)
Data Retrieval
Defrost Start and End
Dehumidification Start and End
Power Loss (w/wo battery pack)
Power Up (w/wo battery pack)

3.6.2 DataCORDER Software
The DataCORDER Software is subdivided into the
Configuration Software, Operational Software and the
Data Memory.
a. Operational Software
The Operational Software reads and interprets inputs
for use by the Configuration Software. The inputs are
labeled Function Codes. There are controller functions
(see Table 3--8, page 3--28) which the operator may
access to examine the current input data or stored data.
To access these codes, do the following:
1 Press the ALT. MODE & CODE SELECT keys.
2 Press an arrow key until the left window displays the
desired code number. The right window will display
the value of this item for five seconds before return-
ing to the normal display mode.
3 If a longer display time is desired, press the ENTER
key to extend the display time to five minutes.
b. Configuration Software
The configuration software controls the recording and
alarm functions of the DataCORDER. Reprogramming
to the factory--installed configuration is achieved via a
configuration card. Changes to the unit DataCORDER
configuration may be made made using the
DataView/DataLINE interrogation software. A listing of
the configuration variables is provided in Table 3--2.
Descriptions of DataCORDER operation for each
variable setting are provided in the following
paragraphs.
3.6.3 Sensor Configuration (dCF02)
Two modes of operation may be configured, the
Standard Mode and the Generic Mode.
a. Standard Mode
In the standard mode, the user may configure the
DataCORDER to record data using one of seven
standard
configurations.
The
seven
standard
configuration variables, with their descriptions, are
listed in Table 3--3.
The inputs of the six thermistors (supply, return, USDA
#1, #2, #3 and cargo probe) and the humidity sensor
input will be generated by the DataCORDER. See
Figure 3--5.
NOTE
The DataCORDER software uses the supply
and return recorder sensors (SRS, RRS). The
temperature control software uses the supply
and return temperature sensors (STS, RTS) .
b. Generic Mode
The generic recording mode allows user selection of the
network data points to be recorded. The user may select
up to a total of eight data points for recording. A list of the
data points available for recording follows. Changing the
configuration to generic and selecting which data points
to record may be done using the Carrier Transicold Data
Retrieval Program.
1. Control mode
2. Control temperature
