Digi ConnectTank Wake-up and Sleep Operation
Digi ConnectTank is intended to run from the internal battery for two years under recommended operating
conditions. To achieve such an extended period of operation, Digi ConnectTank enters into sleep mode for the
maximum amount of time, thus reducing the power consumption to the lowest possible levels. The device
wake-up and subsequent operation is as follows:
•
First time power-up/battery power connection:
The device powers up, detects the battery and
then goes into sleep mode.
•
Factory Default button:
When you press the
Factory Default
button, the device performs the
following functions:
◦
Sets the device configuration to defaults.
◦
Sets the device time.
◦
Uploads device information to Device Cloud.
•
Manual device wake-up by user:
Use the
Wake-up
button wake up the device from sleep. If the
enclosure is closed, you can use the magnetic sensor to wake up the device. On pressing the
Wake-up
button or activating the magnetic switch, the device performs the following functions.
◦
Sends a diagnostic record to Device Cloud with the following device information:
•
Sensor connect status
•
Measured distance reading
•
Measured temperature reading
• GPS location (optional, based on configuration)
•
Battery voltage (the current battery percentage remaining)
• Device configurations
•
Cellular signal strength
◦
Battery and network status LEDs glow indicating their respective functionalities. See the
section for more information on the system status LED sequence.
◦
The device then enters sleep mode.
•
Timed wake-up for data acquisition and reporting:
The device wakes up as per configuration
parameters to perform the following functions:
◦
Monitor the tank liquid level
◦
Report data to Device Cloud
◦
Check for new configuration file from Device Cloud
◦
Check tank level alerts
◦
Check low battery alert
NOTE:
Two year battery life assumes reading and reporting the tank levels twice a day. Battery life may be
significantly shortened by reducing the interval, or lengthened by increasing the interval.
