Data Recorder
Use the built-in DataLink data recorder features
The APX Control System contains a built-in DataLink data recorder with 3 megabytes of memory. It records events as they occur (setpoint changes, defrost cycles, etc.) and logs sensor data at selected intervals in snapshot or averaged format.
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
The data recorder logs four categories of information: • APX Control System Information — date/time, setpoint, trailer ID, unit serial/model number, controller info, pretrip start/end, functional parameters, configurations, and current operating mode • Sensor Data — snapshot or averaged readings from all sensors and transducers at the selected interval • Event Occurrences — setpoint changes, defrost start/end, START/RUN-OFF switch position, pretrip start/end, unit mode, control mode, door/remote switch activations, and hour meter readings • User Area Data — comments entered via the TRU-Tech program
Hour meters are recorded at midnight or the first time of day the START/RUN-OFF switch is toggled from the OFF position. There will be no hour meter readings when the switch is in the OFF position.
Recorded data can be downloaded using either the TRU-Tech/TRU-View program with a PC-USB service cable connected to the USB interface port, or with a Data Transfer USB memory device (refer to Section 5.3.3).
A configuration setting allows an additional 8 hours of sensor data to be recorded after the switch is placed in the OFF position. The factory setting is to record the additional 8 hours so temperatures are captured during unloading, fueling, or other times the unit may be off.
Accessing the Data Recorder
With the system powered up (START/RUN-OFF switch in the START/RUN position), press the MENU key until DATA RECORDER is displayed.
Press the DATA RECORDER soft key. The Data Recorder screen will display with a 15-second timeout.
Press the ▲ or ▼ key to scroll through the available submenus. With the desired submenu highlighted, press the "=" key to enter it.
Marking a Trip Start
From the Data Recorder screen, use the ▲ or ▼ key to highlight MARK TRIP START.
Press the "=" key. If acknowledged, "TRIP START ENTERED" will display for 5 seconds, then the display reverts to normal. A trip begins at a Trip Start and ends at the next Trip Start.
If "CANNOT ENTER TRIP START" flashes on the display, the data recorder is not functioning properly. The display will revert to the Data Recorder menu.
Viewing Recorded Data On-Screen
From the Data Recorder screen, highlight PRINT TO SCREEN and press the "=" key.
If configured, the system will prompt for entry of the data protect PIN code before displaying data.
A graphical representation of recorded data is displayed. Press the ▲ or ▼ key to move through the data day by day. The horizontal axis starts at 00:00 (midnight) with 24 lines representing hours.
Press the "=" key to toggle event codes on or off on the graphical display.
When event codes are ON, the following acronyms appear: • c — Door Close • o — Door Open • d — Defrost start • e — Defrost end • p — Power up • f — Power down • r — Real time clock range • t — Trip Start
