3.10 DATA RECORDER

The APX Control System contains a built-in DataLink data recorder with 3 megabytes of memory. The recorded
data can be downloaded from the DataLink data recorder using either the TRU-Tech/TRU-View program or a Data
Transfer USB memory device.
The DataLink data recorder reads the same input information as the control system (Functional Parameters, Con-
figurations, and Unit Data) at all times. The DataLink data recorder records events as they occur, such as setpoint
changes and defrost initiation and termination, and also records all data values including temperature sensors and
pressure transducers in either averaged or snapshot format at selected intervals.
The following intervals are available for sensor recording:

• 1 Minute
• 2 Minutes
• 5 Minutes
• 10 Minutes
• 15 Minutes

• 30 Minutes
• 1  Hour
• 2  Hours
• 4  Hours

Data Recording

The DataLink data recorder data comes from four general categories of information:
1. APX Control System Information as described in the preceding

Section 3.10.3

2. 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 based on 1 minute increments. The user can
determine which sensor(s) will be recorded, whether snapshot or averaged readings are preferred and at what time
intervals. (Snapshot readings are also taken at the beginning and end of defrost and at the time of a shutdown
alarm.)
All of the sensors and transducers that may be read under Unit Data (refer to

Table 3–1

) may be included or

excluded from the recordings.
3. 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 something that happens and may include:

• Setpoint change
• Defrost cycle start/Defrost cycle end
• START/RUN - OFF switch on (START/RUN

position)

• Pretrip start
• Pretrip end
• Unit Mode

• Control Mode
• Door and Remote switch activations
• Hour Meter readings (Hour meters are recorded

at midnight or the first time of day the START/
RUN- OFF switch is toggled from the OFF posi-
tion. There will be no hour meter readings when
the switch is in the OFF position.

4. User Area Data
The User or service technician may enter a Comment into the DataLink data recorder using the TRU-Tech
program.
