Electronic inputs
Digital Inputs The connector C is a 6 points connector: Pinout is: Inputs characteristics: Only the use of accessories in accordance with the intrinsic safety parameters below is permitted: The schematic of the different inputs of the Toran'O AtEx zone 1 device is illustrated below: It is possible to use the 18-40-263 [AU-06BFFM-QL8D] cable which is a 2m IP68 cable with 6 x 24 AWG wire conductor. It is possible to use the 18-40-298 [AU-06BFFB-QL8AP0] connector: Pinout is: For Elster meter, it is possible to use the 71-70-115-000 2m cable connected to a binder connector on which pin 3 & 4 and pin 6 & 5 are shunted. Pinout is: For Gazpar meter, it is possible to use the 71-70-116 cable which is connected like this: 4-20mA Analog Inputs The connector A for the 4-20mA is a 4 pins: Pinout is: Atex characteristics are: Only the use of accessories in accordance with the intrinsic safety parameters below is permitted: The power supply is intrinsecal protected by a 210 ohm resistor and delivered 16.82Vcc. So the voltage of power supply depends of the current. The voltage is around ~16Vcc@4mA and ~12,6Vcc@20mA. By default the duration of power supply is 125ms. It is configurable until 500ms. It is possible to use the 18-40-262 [AD-04BFFM-QL8D] cable which is a 2m IP68 cable with 4 x 20 AWG wire conductor. It is possible to use the 18-40-299 [AD-04BFFB-QL8AP0] connector: Pinout is: 0-5V Analog Inputs The connector B for the 0-5V is a 6 pins: Pinout is: Atex characteristics are: Only the use of accessories in accordance with the intrinsic safety parameters below is permitted: The power supply is intrinsecal protected by a 100 ohm resistor and delivered 5.62Vcc. So the voltage of power supply depends of the current. The voltage is around ~5.5Vcc@1mA, ~5.1Vcc@5mA, ~4.6Vcc@10mA and ~4.1Vcc@15mA. By default the duration of power supply is 125ms. It is configurable until 500ms. It is possible to use the 18-40-263 [AU-06BFFM-QL8D] cable which is a 2m IP68 cable with 6 x 24 AWG wire conductor. It is possible to use the 18-40-298 [AU-06BFFB-QL8AP0] connector: Pinout is: The housing is intended to be installed inside or outside a building but it must be protected from vertical water spray and direct sunlight. Flammability rating: UL94HB Ingress protection: IP55 or IP68 48 hours @1m In order for the sensor to operate correctly, the number of obstacles should be limited in order to avoid excessive radio wave attenuation. It is also important to place the sensor as high as possible. The cable gland should be positioned on left side. The information in the table below represents how long the battery can last. It is based on the default configuration at ambient temperature (+25°C) within the optimal operating range of the sensor via a LoRaWAN network (one uplink frame), when the spreading factor used is SF12. The disposable battery has a 3.6Ah capacity, of which 85% is used. A value of 3µA of consumption is added per input connected (contact closed). There are Two LEDs on the Toran'O AtEX zone 1 device: ASSN: blinking until the association with a network is done. Since release v3.5.2.5530, after 6 hours in association searching the led blinks all 1 minute. CNF: blinking in configuration mode. To start up the device, a magnet must be placed next to the sensor for one second (behind the "ILS" sticker). The red LED blinks quickly during this step. After one second, the red LED stops blinking and the green LED blinks slowly until the association is done. To switch off the device, repeat the same operation by placing the magnet next to the sensor for 5 seconds. After those 5 seconds, the red LED blinks 5 times slowly. A reed switch is available under the "ILS" sticker. A magnet can be used to activate it and perform specific actions on the sensor (switch off, switch on, reassociation…). When the reed switch is activated, the red LED blinks quickly. The sensor keeps the AppEUi and DevAddr configured, Confirmed/Unconfirmed configuration and all applicative configurations. However, LoRaWAN configurations (channel, data rate …) are lost. The sensor keeps the AppEUi and DevAddr configured. However, LoRaWAN configurations (channel, data rate…) and applicative configurations are lost. Codecs are available to decode frames: Downloads Encoder are available on Online Codec The Toran'O AtEx Zone 1 device implements “Binary Input” cluster associated to its Inputs. The link between the connectors and the EndPoint is given below: The Toran'O AtEx Zone 1 device implements “Analog Input” cluster associated to its 4-20mA and 0-5V Inputs. The link between the connectors and the EndPoint is given below: Toran'O integrates the following clusters: A default configuration is set: Every change made to the default configuration must comply with the legal duty cycle (for example, the most restrictive in the EU is 0.1%, which corresponds to approximately 1 frame per hour with SF12) All frames have to be sent on port 125 Report of the state of connector input 1+/1- → Applicative payload is: 11 0a 00 0f 00 55 10 01 11: Fctrl (Endpoint=0) 01: current binary value Report the counter associated to connector input 2+/2- →Applicative payload is: 31 0a 00 0f 04 02 23 00 00 00 01 31: Fctrl (Endpoint=1) 00 00 00 01: current value of the counter

Way to trigger it One passage of the magnet near the reed switch or specific ZCL command
Way to stop it Another passage of the magnet or specific ZCL command
Effects on the sensor The CONF led (red) blinks (3 sec. OFF, 3 sec. ON) and the sensor sends an uplink frame every minute.
Duration The configuration mode lasts 10 minutes
Way to trigger it Three passages of the magnet near the reed switch or ZCL command from LoRaWAN cluster.
Effects on the sensor The ASSN led (green) blinks as the “no commissioned sensor” LED is lit.
