4.7.2 DataCORDER Software
The DataCORDER Software is subdivided into the Operational Software, Configuration 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. Controller functions (see
Table 4–8 ) 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 and 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 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 using the DataLINE interrogation software. A listing of the configuration variables is provided in
Table
4–2 . Descriptions of Data CORDER operation for each variable setting are provided in the following paragraphs.
4.7.3 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 con-
figurations. The seven standard configuration variables, with their descriptions, are listed in
Table 4–3 .
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 4.11 .
NOTE
The DataCORDER software uses the supply and return recorder sensors (SRS, RRS). The tempera-
ture 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
3. Frequency
4. Humidity
5. Phase A current
6. Phase B current
7. Phase C current
8. Main voltage
9. Evaporator expansion valve percentage
10. Discrete outputs (Bit mapped - require special
handling if used)
11. Discrete inputs (Bit mapped - require special
handling if used)
12. Ambient sensor
13. Evaporator temperature sensor
14. Compressor discharge sensor
15. Return temperature sensor (RTS)
16. Supply temperature sensor (STS)
17. Defrost temperature sensor
18. Discharge pressure transducer
19. Suction pressure transducer
20. Condenser pressure transducer
21. Vent position sensor (VPS)
