Page 9: Identification
c. Identification The product's LoRaWAN identifier is printed on the sensor and in the status bar of the ACW configurator. It can also be read by scanning the QR-Code. For LoRaWAN modems, the communication keys are automatically given by the network (pairing by "Over The Air Activation", or OTAA). -
Page 10: Operating Diagram
For currents above 40ARMS, charging time does not drop below 10mn. In normal operation, if the line current drops below 1ARMS, the energy recovery stage is deactivated. The sensor will continue to operate on stored energy for approximately 30 minutes. When the current in the phase is restored, the time required to restart is given by the graph below : In continuous operation, a line current of amplitude 1.2ARMS is sufficient to supply the transducer with the energy required by the system without using the energy stored in the storage element. - Page 11 ATIM_ACW-CTS_UG_EN_V1.2...

ACW Configurator a. Compatible configurator versions For a sensor with the following application software Use the ACW Configurator version version LoRaWan: V1.0.5 (revision A0) V1.0.4 or higher Download and install the setup software ''setupACW.exe'' at : https://www.atim.com/wp-content/uploads/documentation/CONFIGURATEUR/ACW/configurateur-acw.exe When the ACW Configurator is launched, the waiting window appears on the screen. WARNING Connection to the configurator is only possible in local mode (BLE). -

b. eGreenSensor configuration Transmission period and frame samples The transmission period corresponds to the time interval between each transmission of a measurement frame. This period can be configured from : 1 min to 255h for a LoRaWan product The default transmission period is 10min. - Page 14 frame n-1, n-2 or n-3 can be sent again in frame n following the new measurement samples (the most recent sample first in the frame and the oldest last). For example, for a history depth of 3, data from the last 2 frames will be sent, in addition to new data, in the next frame.

Page 15: Communication Interface
Communication interface The product has two communication interfaces : LoRaWAN The BLE interface can be activated or deactivated using the parameter LoRaWAN interface cannot be disabled. WARNING If the BLE interface is deactivated, it will no longer be possible to connect to the configurator. The configurator can only be accessed via BLE. -
Page 16: Radio Module Configuration
Radio module configuration The product can operate in three different ways For a LoRaWAN product 1. LoRaWAN Class A : The product is modulated in LoRa using the LoRaWAN Class A protocol. This is the product's default mode. This mode requires a private LoRaWAN network (private gateway), or an operated network to view the data sent by the product. -
Page 17: Product Clock
Product clock Each time you connect to the configurator, the product clock is updated (based on the computer clock) and displayed. In addition, an offset in seconds can be applied if required. Product versions When connected to the product, the configurator retrieves all product software versions (product software and radio module software) and the network identifier. -
Page 18: Sensor Configuration
Sensor configuration Here are the configuration parameters available for this sensor Thermocouple activation The ACW-CTS has a connector for type K thermocouples. If such a thermocouple is used, the thermocouple must be activated in the configurator, so that the measurement is carried out, and the temperature is also transmitted via the LoRaWAN interface. By default, the thermocouple is not activated. -
