Product Identification The Sigfox or LoRaWAN IDs of the product are visible on the outside label on the side of the product, inside on the electronic card, and in the status section of the ACW configurator. For LoRaWAN modems, the communication keys are automatically given by the network (pairing by "Over The Air Activation", or OTAA).
Installation and dismantling It is necessary to open the box to the micro-USB port allowing the configuration of the module. To do this, you must unscrew the four screws which hold the top and bottom of the enclosure together. Screws to dismount the enclosure.

IMPORTANT NOTE Avoid all kind of obstruction around the output of the sensor, especially in closed environments like a tank. A drilling of 60mm diameter is recommended. WARNING Take care about the size of the walls, the longer they are, the more interferences can happen. This can lead to false measurements or even prevent the sensors to work.
Be careful with the dimensions of the tank drilling: There is a constraint in the depth of drilling of the tank, if it is not respected, there is a risk of rebounds of the signal what can entrain errors of measurement. Z is the depth of the wall in mm &...
Operating Operating modes The operating of the ACW-LVL is divided between different modes: Operation mode: this is the default mode when starting the product. In this mode, the module periodically sends measurements according to the configuration applied (if the product has never been configured, the factory configuration applies, see Factory settings).
Product start-up In most cases, the ACW-LVL is started up before delivery (battery packs already connected) and then placed in deep standby to limit consumption. To place the product in its operating mode, bring a magnet close to the side of the case for 6 seconds. During these 6 seconds, the product LED should flash WHITE and then...
Test frame emission When the product is in its operating mode (and only in this mode), it is possible to send a test frame (which avoids waiting for the next measurement frame) including a measurement sample. To do this, simply bring the magnet closer until the GREEN light signal goes out.
ACW configurator Compatible configurator version For an LVL with the following application software version: Use the version of ACW Configurator: Sigfox: V1.0.6 V5.3.1or later LoRaWAN: V1.0.6 Download and install the configuration software setup ’setupACW.exe‘ at: https://www.atim.com/en/products-configurator/ NOTE The ACW-LVL can be configured only from its configuration mode (otherwise the ACW configurator cannot detect it). To enter configuration mode, the device must enter its deep sleep mode first (magnet for 6 seconds), wait approximately 20 seconds for the entry to be effective and then wake up the device (magnet for 6 seconds again).
ACW-LVL setup Emission period and samples in the frame The transmission period corresponds to the time interval between each sending of a measurement frame. This period can be configured from 10 min to 255 h and its default value is 1 hour. In addition, it is possible to configure the number of samples in a frame .
Frame timestamp It is possible to deactivate / activate the time stamping of all radio frames WARNING This option when activated monopolizes 4 bytes in the frame which cannot be used for useful data. Configuration of the Radio module The device can work in 3 different operating modes •...
o Local mode: The modulation of the frame’s switches to FSK. In this mode, you must choose the radio channel on which the product will transmit. To be able to receive the product frames, a radio modem with the same parameters is then required. This mode has no real concrete use case for the moment, but future developments of this mode will provide interesting point-to-point features.
The gray slots on the graph correspond to the amplitude thresholds, defined by the range in width and amplitude threshold in height. Setup validation After having filled in all the configuration parameters, it is essential to click on the "Apply to ACW" button to send the configuration to the product It is also possible at any time to read the current configuration of the product which will update the parameters on the configurator or to reset the default configuration of the product.
Factory settings Radio frames settings: Radio frame emission period: 10 minutes Number of samplings: 1 History depth: 1 General settings: Keep alive frame emission period: 4 days Timestamp: disabled Radio parameters: LoRaWAN Class A (for a LoRAWAN product) / Sigfox (For a Sigfox product) Sensor’s parameters: Level offset: 0 cm Threshold parameters...

For each channel, a header is inserted afterwards and is constituted as follows: Channel header Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 Reserved = 0 Channel’s number Type of measurement In the case of ACW-LVL, the measurement type is 0x07 on 2 bytes for the distance in centimetres. In the case of the ACW-LVL, there is only 1 way (i.e.
For each of the channels in alert a header is inserted and is constituted as follows: Channel Header Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 Alert type Channel’s number Measurement type The type of alert field is used to identify whether it is a breach of the high threshold, the low threshold, or a return between the thresholds.
