a. Operational Software
The operational software reads and interprets inputs for
use by the configuration software. The inputs are
labeled Function Codes. There are 35 functions (see
Table 3-10, page 3--25), 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 returning
to the normal display mode.
3. If a longer time is desired, press the ENTER key to ex-
tend the time to 30 seconds.
b. Configuration Software
The configuration software controls the recording and
alarm functions of the DataCORDER. Reprogramming
to the factory-installed configuration is achieved via the
same configuration card as the unit control module
software. Changes to the software may be made made
using the Data View integration device. 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)
T wo 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
listedinTable3-3.
The six thermistor inputs (supply, return, USDA #1, #2,
#3, and cargo probe) and the humidity sensor input will
be generated by the DataCORDER. An example of a
report using a standard configuration is shown in
Figure 3-5.
NOTE
The DataCORDER software uses the supply
and return recorder
sensors. The temperature
control software uses the supply and return
temperature
sensors.
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
3. Frequency
4. Humidity
5. Phase A current
6. Phase B current
7. Phase C current
8. Main voltage
9. Suction modulation valve percentage
10. Discrete outputs (See Note )
11. Discrete inputs (See Note )
12. Ambient sensor

14. Compressor discharge sensor
15. Return temperature sensor
16. Supply temperature sensor
17 Defrost temperature sensor
18. Discharge pressure transducer
19. Suction pressure transducer
20. Condenser pressure transducer
