Checking the Logger's Status

At any stage while the logger is not charging you can check its operational status by briefly pressing the Start/Check button for one second.

  • OK LED (green) lights for 3 seconds
    The logger is operating normally and its battery charge level is sufficient for transmitting live data to LogTag® Online.
  • Alert LED (red) lights for 3 seconds
    The logger is recording, but its battery is no longer sufficiently charged to transmit live data to LogTag® Online. Transmission is suspended to save battery life.
  • OK LED blinks for 3 seconds
    The logger’s battery charge level is sufficient for transmitting data, but the last transmission attempt failed (for example, if no cellular signal was available at the time the transmission was attempted). Transmission will resume at the next scheduled interval.
  • Alert LED blinks for 3 seconds
    The logger’s battery is no longer sufficiently charged to transmit live data, and the last transmission attempt failed. The transmission will not resume until the logger is re-charged. In this case, please refer to the section about Missing Data.
  • None of the LEDs light
    The logger's battery is empty and requires charging.

Shipper

The Shipper Guide consists of the following sections. Use the links below to jump to the section you need to read more about.

Charging the Logger

Before you start a logger check its battery status by briefly pressing the Start/Check button.

If the red ALERT LED lights, the battery is only partially charged; the logger can be started, but may not have sufficient battery left to cover the intended trip.

  1. Remove the protective socket cover at the bottom of the logger.
  2. Plug the USB-C end of the charger cable into the logger's USB-C socket and supply power. We recommend you only use a high-quality charger from a reputable manufacturer. The logger will not charge when plugging it into a PC's USB-C port.
  3. The logger indicates it is charging by turning on its red Alert LED.
  4. When fully charged, the green OK LED will permanently turn on.

The logger is now ready for use.

If the green OK LED lights, the battery is at least 80% charged. We recommend you charge the logger before you add it to a shipment, regardless of battery status, to maximize trip duration.

Starting the Logger

Ensure your compatible external probe is connected to your logger securely. Popular probes compatible with the LT5GEO external loggers can be found in the Accessories section.

For a full list of compatible probes, see our External Probe Brochure

Press and hold the Start/Check button for 4 seconds. The green LED will turn on, indicating the charge level is OK. If the red LED turns on, charge the unit before continuing with the start procedure. Release the button when both LEDs flash in an alternating pattern. The logger will:

  • Connect to LogTag® Online and request any updates to its configuration data
  • Start recording environmental and positioning data and transmit this to LogTag® Online

Add the logger to the monitoring environment. For accurate shock data, use the included adhesive strip and mount the logger to a solid surface.

Back to Start ▲     Back to Shipper▲

During Recording

Once started, the LT5GEO will record the following environmental data:

  • Temperature 
  • Light level
  • Shock

If your logger is using external power, it will upload environmental data to LogTag® Online every 10 minutes. If it is using the loggers internal battery, it will upload every data every hour. When an alarm is triggered, the logger will attempt to upload data instantly.

For data to be transmitted, the LT5GEO must be allocated to a shipment in LogTag® Online. If you do not complete the required setup steps, you will not receive any data the logger records.

While logging, the green LED will blink every 4 seconds if the logger has not triggered an alarm. The red LED will blink if an alarm has been triggered.

LogTag® Online can give you additional information about the LT5GEO's battery status, its expected remaining recording duration and the expected transmission interval.

Receiver

The Receiver Guide consists of the following sections. Use the links below to jump to the section you need to read more about.

Receiving Cargo with an LT5GEO

When the cargo has reached its destination, there is no need to recover the logger as it will have transmitted your data to your LogTag® Online account throughout the trip.

Login to LogTag® Online and open the "Shipments" page. Click the line with the shipment to which the logger was added and check that you have received all of your expected data. If all your expected data is in your report, click  Complete Shipment . This concludes data collection for the shipment so no erroneous data is transmitted, as the logger will continue to transmit until it receives a confirmation message from LogTag® Online. If LogTag® Online receives geo-location data which indicate the logger is positioned inside the destination zone, the shipment will auto-complete after 14 days, and the logger will stop recording and transmitting data.

If you have not received all of your expected data, follow the steps in the Troubleshooting section.

Once the logger has stopped recording, please return it to a LogTag North America distributor for disposal, or have it refurbished for a fee.

Back to Start ▲     Back to Receiver▲

Troubleshooting

The LT5GEO may arrive at the destination, but you cannot see all data from the trip in LogTag® Online. You can identify this by recovering the logger and checking the logger's status. If no LEDs light when you press the Start/Check button for 1 second, or you see a transmission error signal, the logger did not transmit some of the recorded data.

If this happens, do the following:

  • Charge the unit until the green OK LED lights up steadily. If the battery is very low, the red LED will blink slowly, and you will not be able to access the data. Remove the charger and press the Start/Check button to upload the data via the cellular network. You should see the green OK LED light, and the data will be available in LogTag® Online shortly after you have pressed the button (provided there is cellular coverage). Note that charging from a very low battery could take several hours.
  • If this fails, or the data is needed immediately, navigate to https://lt.help/lt5geo/download/ in your PC’s browser and follow the instructions. This requires you to connect the logger to a PC and download a small program that can extract the data from the LT5GEO and upload it to LogTag® Online via your internet connection.
