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 unit DataCORDER configuration 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)

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. Standard configuration variables, with descriptions, are listed in Table 3-3.

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 (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

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 (Bit mapped - require special handling if used)

11.Discrete inputs (Bit mapped - require special handling if used)

12.Ambient sensor

13.Compressor suction sensor

14.Compressor discharge sensor

15.Return temperature sensor

16.Supply temperature sensor

17Defrost temperature sensor

18.Discharge pressure transducer

19.Suction pressure transducer

20.Condenser pressure transducer
