3.19 DataLink DATA RECORDER
The Advance microprocessor contains a built-in
DataLink data recorder with 512K of memory. The re-
corded data can be downloaded from the DataLink data
recorder using either ReeferManager or a Download PC
card.
The DataLink data recorder reads the same input infor-
mation as the microprocessor (Functional Parameters,
Configurations, and Unit Data) at all times. The
DataLink data recorder records events as they occur,
such as set point changes and defrost initiation and ter-
mination, and also records all data values including tem-
perature sensors and pressure transducers in either av-
eraged or snapshot format.
The following intervals are available for sensor record-
ing:
2 Minutes
5 Minutes
10 Minutes
15 Minutes
3.19.1 Microprocessor Information
The microprocessor information that may be recorded is
as follows:
S DataLink data recorder setup (Logging Intervals,
Events and Sensors)
S DataLink data recorder time clock date / time
S Set points
S ID Number
S Unit Serial Number
S Unit Model Number
S Trailer ID
S Current System Mode
S Functional Parameters
S Microprocessor Configurations
3.19.2 Data Recording
The DataLink data recorder data comes from four gen-
eral categories of information:
a. Microprocessor Information as described in Section
3.19.1 above.
62-11389
30 Minutes
1 Hour
2 Hours
4 Hours
b. Sensor Data
This information is recorded at pre-determined intervals
as a snapshot of the sensor at the time of the recording,
or an averaged reading of the sensor readings since the
last recording. The user can determine which sensor(s)
will be recorded, at what intervals, and whether snap-
shot or averaged readings are preferred. (Snapshot
readings of sensors are also taken at the time of a shut-
down alarm.)
All of the sensors and transducers that may be read un-
der Unit Data (refer to Table 3-1) may be included or ex-
cluded form the recordings.
c. Event Occurrences
This information is any additional data that is recorded
on a "when it occurs" basis. Events are recorded by the
recorder as they occur. An Event is defined as some-
thing that happens and may include:
S Set point change
S Defrost cycle start
S Main power on
S Pretrip start
S Pretrip end
S Unit mode (Start-Stop or Continuous Operation)
S Control mode (Heat, Cool, High/Low speed, etc)
S Door and Remote switch activations.
S Hour Meter readings (Hour meters are recorded at
midnight or the first time of day the Main Power switch
is toggled out of the OFF position.
d. User Area Data
The User or service technician may enter a Comment
into the DataLink data recorder using the ReeferMan-
ager program.
3.19.3 Data Downloading
The data within the DataLink data recorder can be
downloaded using either the ReeferManager program
with a download cable connected to the download port
or with a Download PC card (refer to Section 5.3). If a
PC card is used, the ReeferManager program is then
used to extract the data from the PC card, and place it on
the computer hard disk.
3.19.4 DataLink Data Recorder Power-Up
The DataLink data recorder records data the entire time
the Main Power switch is not in the OFF position. A Con-
figuration exists which allows the user to select either an
additional 8 hours of sensor data be recorded after the
switch is placed in the OFF position, or to stop recording
at the same time the switch is placed in the OFF posi-
tion. The factory setting is to stop recording at the same
time the switch is placed in the OFF position. (Refer to
Section 5.2.1.)
