Product Description
Manual InstructionBrief InstructionLVR91 integrates smart meter, enclosed circuit breaker, and wireless collector. This device can realize high-precision metering of single-phase/three-phase AC power supply circuit, and a built-in power control of various smart logics. The communication interface realizes two-way communication with cloud center, and realizes the integrated functions of data acquisition, logic control, remote communication and circuit fault detection Combined with the operation of the platform, it can further realize the extended functions to cut off line while power credit overdue. Multi-rate charging mode can be implemented, and related commands can be transmitted and executed through RS485 encryption. The over-current protection value can be freely set. When the power consumption is small, a relatively small current is set, otherwise, a relatively high current can be set, so that the output end.RS485 Communication1.This device has Rs485 Modbus communication terminal. Users can use cable of USB to Rs485 to connect device with computer to control and configure. 2.The system has default speed (baud rate) 9600 bps, which can be viewed from "device information" "communication connection".3.More details about Rs485, please contact for appendix 1.GPRS Communication1.LVR91 network version has GPRS communication which connects the device and platform to realize info exchange and remotely operation.2.Please refer the appendix 2 for more details to connect device with platform.3.Through GPRS, the device can monitor energy power in real time, to check and analyze all power data, monthly statistics, and settlement.Power Meter Function1.Energy Power MeteLVR91 has total active power, net active power, consumed active power, released active power and corresponding reactive energy metering function.2.Clock Built-in hardware clock circuit with temperature sensor, calendar, timing, and leap year automatic conversion function.3.Data storageIt can store the total energy of 12 settlement days for each energy tariff data, the spot time of data transfer is 24: 00, at integer hour of month from 1st to 28th.4.FrozenDaily Frozen: it can store daily electric energy from 00: 00, and store data up to 62 days. When the power is off, he daily frozen data will be recovered when the.5.Event Record5.1 Record total power off times, also start and end time of recent 10 power off.5.2 Record energy data clear times, also, start and end time of recent 10 times.

Unlock releaseIdentified the circuit fault, the electrician should pull out the safety lock and hang with a lock to solve the problem. Then, push back the safety lock, and try manually switch on the handle. If unsuccessful, electrician needs to check credit overdue, or remotely switched off, either by Rs485 or GPRS.Safety lockIt is under operation mode while safety lock not pulled out.It is under maintenance mode while safety lock is pulled out and needs to hang a lock. This safety lock has interlock with handle, and can't switch on, even manually, while lock pulled out More security to maintenance electrician.Installation and Test
