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.

Power off Remove Batteries.
Note
1.The device will be off after removing the battery and insert it again.
2.It is suggested to wait for at least 10 seconds between turning the device on and off.
3.At 1st -5th second after power on, the device will be in engineering test mode.
Network Joining
If the device has never joined the
network
Turn on the device, and it will search for the network to join.
The green indicator light stays on for 5 seconds: joins the network successfully

The device will immediately send a version packet report along with an uplink packet including current,illuminance and battery voltage.
The device sends data in the default configuration before any configuration is done.
Default setting:
Maximum time: Max Interval =15 min (900 s)
Minimum time: Min Interval =15 min (900 s) *Please configure more than 30 seconds
CurrentChange:0x0064 (100 mA)
IlluminanceChange: 0x0064 (100 Lux)
Light sensor support 3 ranges of Illuminance:
0x00, 3~65000 Lux (default)
0x01, 3~130000 Lux
0x02, 3~220000 Lux
Note:
(1) The device report interval will be programmed based on the default firmware which may vary.
(2) The interval between two reports must be the minimum time.
(3) If MinTime configuration less than 30 seconds, it will configure 30 seconds.
(4) R718NL3 series would take about 15 seconds for the CT to sample and process the collected value, If the current changes frequently, the
sampling result might be wrong.
Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver http://www.netvox.com.cn:8888/page/index to

Notes :
1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, 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.

6. Installation
This product comes with waterproof function.
When using it, the back of it can be adsorbed on the iron surface, or the two ends can be fixed to the wall with screws.
When installing the current transformer, separate the fire and neutral wires, and take out the fire wire separately and start the measurement according to
the wiring below.
Note:
Please do not disassemble the device unless it is required to replace the batteries.
Do not touch the waterproof gasket, LED indicator light, function keys when replacing the batteries. Please use suitable screwdriver to tighten the
screws (if using an electric screwdriver, it is recommended to set the torque as 4kgf) to ensure the device is impermeable.

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 the batteries should be produced within the last three months.
If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis.
7.1 To determine whether a battery requires activation
Connect a new ER14505 battery to a 68ohm 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 68ohm resistor in parallel
b. Keep the connection for 6~8 minutes
c. The voltage of the circuit should be ≧3.3V
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, or any liquid, might contain minerals and thus corrode electronic circuits. If the device gets wet, please dry it
completely.
• Do not use or store the device in dusty or dirty environment. It might damage its detachable parts and electronic components.
• Do not store the device under excessive heat condition. High temperature can shorten the life of electronic devices, destroy batteries, and deform or
melt some plastic parts.
• Do not store the device in places that are too cold. 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. Rough handling of equipment can destroy internal circuit boards and delicate structures.
• Do not clean the device with strong chemicals, detergents or strong detergents.
• Do not apply the device with paint. Smudges might block in the device and affect the operation.
• Do not throw the battery into the fire, or the battery will explode. Damaged batteries may also explode.
All of the above applies to your device, battery and accessories. If any device is not working properly, please take it to the nearest authorized service
facility for repair.
