Introduction R718KA is a current detection device for Netvox Class A type devices based on LoRaWAN open protocol. The device is suitable for detecting 4mA to 20mA current, and R718KA is compatible with LoRaWAN protocol. LoRa Wireless Technology: LoRa is a wireless communication technology famous for its long-distance transmission and low power consumption. Compared with other communication methods, LoRa spread spectrum modulation technique greatly extend the communication distance. It can be widely used in any use case that requires long-distance and low-data wireless communications. For example, automatic meter reading, building automation equipment, wireless security systems, industrial monitoring. It has features like small size, low power consumption, long transmission distance, strong anti-interference ability and so on. LoRaWAN: LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and gateways from different manufacturers. 2 2.

Set up Instruction On/Off Power on Insert batteries. (users may need a screwdriver to open) Turn on Press and hold the function key for 3 seconds till the green indicator flashes once. Turn off (Restore to factory setting) Press and hold the function key for 5 seconds till green indicator flashes 20 times. Power off Remove Batteries. Note: 1. Remove and insert the battery; the device is at off state by default. Turn on the device to use again. 2. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor inductance and other energy storage components. 3. 5 seconds after power on, the device will be in engineering test mode. Network Joining Never joined the network Turn on the device to search the network to join. The green indicator stays on for 5 seconds: success The green indicator remains off: fail Had joined the network (not at factory setting) Turn on the device to search the previous network to join. The green indicator stays on for 5 seconds: success The green indicator remains off: fail Fail to Join The Network Suggest to check the device verification information on the gateway or consult your platform server provider. Function Key Press and hold for 5 seconds Restore to factory setting / Turn off The green indicator flashes for 20 times: success The green indicator remains off: fail Press once The device is in the network: green indicator flashes once and sends a report The device is not in the network: green indicator remains off Sleeping Mode Sleeping period: Min Interval.

When it is on sleeping mode, it does not collect data. 2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value, the device reports according to MinTime interval. If the data variation is not greater than the last data reported, the device reports according to MaxTime interval. 3) We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up frequently and the battery will be drained soon. 4) Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval, another cycle of MinTime/MaxTime calculation is started. 8 6. Installation 1. Wireless Current Meter Interface (R718KA) has the built-in magnet (as the figure below). When installed, it can be attached to the surface of an object with iron which is convenient and quick. To make the installation more secure, use screws (purchased) to secure the unit to a wall or other surface (as the figure below , the installation diagram of R718A is taken as an example because the main body has the same appearance). Note: Do not install the device in a metal shielded box or in an environment with other electrical equipment around it to avoid affecting the wireless transmission of the device. 2. Connect the sampling line of the current meter interface sensor to the transmitter according to the wiring method shown in figure. There are two connection modes, 2-wire and 3-wire. 3. When the ADC sampling interface sensor detects the current voltage according to the configured time or by pressing the button, it sends the data immediately Wireless Current Meter Interface (R718KA) It can also be applied to the following scenarios: Pressure transmitter Differential pressure transmitter Level transmitter Flow transmitter The transmitter with 4-20mA output signal Power Power Connect to Transmitter + Pole 4 ~ 20mA Signal Connect to Transmitter Signal Port Pressure Transmitter Connect to Transmitter + Pole 4 ~ 20mA Signal Connect to Transmitter Signal Port Pressure Transmitter Figure1 2-wire System Example Diagram (for wiring reference) 9 Figure2 3-wire System Example Diagram (for wiring reference) 7. Information about Battery Passivation Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high. This lithium chloride layer prevents rapid self-discharge caused by continuous reaction between lithium and thionyl chloride, but battery passivation may also lead to voltage delay when the batteries are put into operation, and our devices may not work correctly in this situation. As a result, please make sure to source batteries from reliable vendors, and it is suggested that if the storage period is more than one month from the date of battery production, all the batteries should be activated. If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis. ER14505 Battery Passivation: 7.1 To determine whether a battery requires activation Connect a new ER14505 battery to a resistor in parallel, and check the voltage of the circuit. If the voltage is below 3.3V, it means the battery requires activation. 7.2 How to activate the battery a. Connect a battery to a resistor in parallel b. Keep the connection for 5~8 minutes c. The voltage of the circuit should be 3.3, indicating successful activation. Brand Load Resistance Activation Time Activation Current Note: NHTONE RAMWAY EVE SAFT 165 67 67 67 5 minutes 8 minutes 8 minutes 8 minutes 20mA 50mA 50mA 50mA If you buy batteries from other than the above four manufacturers, then the battery activation time, activation current, and required load resistance shall be mainly subject to the announcement of each manufacturer. 10 8. Important Maintenance Instruction Kindly pay attention to the following in order to achieve the best maintenance of the product: · Keep the device dry. Rain, moisture and various liquids or water may contain minerals that can corrode electronic circuits. In case the device is wet, please dry it completely. · Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components. · Do not store in excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts. · Do not store in excessive cold place. Otherwise, when the temperature rises to normal temperature, moisture will form inside which will destroy the board. · Do not throw, knock or shake the device. Treating equipment roughly can destroy internal circuit boards and delicate structures. · Do not wash with strong chemicals, detergents or strong detergents. · Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation. · Do not throw the battery into the fire to prevent the battery from exploding. Damaged batteries may also explode. All the above suggestions apply equally to your device, batteries and accessories. If any device is not operating properly, please take it to the nearest authorized service facility for repairing. 11
