Power Management

To protect the device from damage and data loss, a correct wiring and configuration of the power management settings is mandatory. The main purpose of the power management settings is that the device has a safe shutdown before the supply voltage (terminal 30/31) is disconnected.

The Power Management settings allow you to configure how the device enters sleep mode and which events can wake it up again. Proper configuration helps reduce power consumption while ensuring that the device remains responsive to required wake-up triggers, such as movement or scheduled intervals. The Power Management settings can be accessed through the device Web UI under Advanced settings > Power management settings.

Note

Wake-up of the device is possible when at least one of following condition is fulfilled:

  • The IO - Clamp 15 (Ignition) State is at level high (> 6 V)
  • The Enable accelerometer as a wake-up source option in the power management settings is enabled and the configured threshold is exceeded
  • The Enable RTC interval as a wake-up source option in the power management settings is enabled and the configured time is elapsed

The following subsections provide an overview of the individual power management functions.

For further information see also chapter Switching the Device On/Off.

Enable Sleep Mode

Enabling Sleep mode allows the device to automatically reduce power consumption when no activity is required. When this option is activated, all configured sleep and wake-up mechanisms become active.

To enable Sleep Mode, proceed as follows:

  1. Enable Sleep mode.
  2. Configure the desired optional sleep triggers described below.

Enter Sleep Mode After Delay

The Enter sleep mode after delay parameter defines how long the device continues normal operation before entering sleep mode once Sleep Mode has been enabled.

You can configure this setting as follows:

  1. Enable Sleep mode.
  2. Enter the desired delay time (in seconds).
  3. Apply the configuration.

Note

Ensure that the delay is long enough to allow pending tasks to finish before the device goes into sleep mode.

Accelerometer Wake-Up Source

The internal accelerometer can be used as a wake-up trigger when the device is in sleep mode. When enabled, the device wakes up as soon as the detected acceleration exceeds the configured threshold.

To configure accelerometer wake-up, proceed as follows:

  1. Enable Accelerometer as a wake-up source.
  2. Set the Acceleration wake-up threshold (in g). The minimum delta value for the threshold is 0.2 g, resulting in an actual wake-up force of 1.2 g on the sensor. The maximum value for the acceleration wake-up threshold is 16 g.
  3. Apply the configuration.

Note

Choosing a threshold that is too low may cause frequent unintended wake-ups due to vibration or handling.

RTC Interval Wake-Up Source

The RTC wake-up interval function allows the device to periodically wake up at a defined interval using its internal real-time clock.

To configure RTC interval wake-up, proceed as follows:

  1. Enable RTC interval as a wake-up source.
  2. Enter the RTC wake-up interval in seconds.
  3. Apply the configuration.

Note

Choose the interval based on the required update or reporting frequency. Very short intervals may reduce power-saving benefits.

Temporary Disable Wake-Up Sources During Transportation

This option allows you to temporarily disable all wake-up sources during transport, storage, or shipment. When enabled, neither accelerometer wake-up nor RTC interval wake-up will cause the device to start unintentionally.

To enable transport protection, proceed as follows:

  1. Enable Temporary disable wake-up sources during transportation.
  2. Apply the configuration.

Note

Once the device is deployed and requires regular operation, ensure that this option is disabled again to restore normal wake-up behavior.

Timeout for Sending Wake-Up Reason

The Timeout for sending a wake-up reason to the server parameter defines how long the device should keep trying to upload this information before going back to sleep.

When the CANlink® mobile 10000 wakes up or boots, it automatically attempts to send its wake-up reason to the DataPlatform. In some situations, this upload may not be possible, for example due to missing network coverage or temporary connectivity issues.

To configure this setting, proceed as follows:

  1. Set the desired Timeout for sending a wake-up reason (in seconds).
  2. Apply the configuration.

If the wake-up reason cannot be transmitted within the configured timeout, the device will return to sleep mode and retry at the next wake-up event.

Note

A longer timeout increases the likelihood of a successful upload but may temporarily reduce power-saving efficiency, especially in areas with poor connectivity.
