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 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 a
configuration card. Changes to the unit DataCORDER
configuration may be made using the DataLINE
interrogation software.
A list of the configuration variables is provided in
2. Descriptions of DataCORDER operation for
each variable setting are provided in the following
paragraphs.
3.7.3 Sensor Configuration (dCF02)
Two modes of operation may be configured, the Stand-
ard Mode and the Generic Mode.
a. Standard Mode
In the standard mode, the user may configure the Data-
CORDER to record data using one of seven standard
configurations. The seven standard configuration vari-
ables, with their descriptions, are listed in Table 3
The inputs of the six thermistors (supply, return, USDA
#1, #2, #3 and cargo probe) and the humidity sensor in-
put will be generated by the DataCORDER. See
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. 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. Evaporator pressure transducer
21. Vent position sensor (VPS)
3.7.4 Logging Interval (dCF03)
The user may select four different time intervals be-
tween data recordings. Data is logged at exact intervals
in accordance with the real time clock. The clock is fac-
tory set at Greenwich Mean Time (GMT).
3.7.5 Thermistor Format (dCF04)
The user may configure the format in which the thermis-
tor readings are recorded. The short resolution is a 1
byte format and the long resolution is a 2 byte format.
The short requires less memory and records tempera-
ture with variable resolutions depending on temperature
range. The long records temperature in 0.01
C
(0.02
F) steps for the entire range.
