One application scope
The series of split residual current electrical fire monitoring detectors are produced by our company in strict accordance with the national standard B "Residual Current Development and design of electrical fire monitoring detector. A new type of residual current electrical fire monitoring detector (hereinafter referred to as the monitor) is designed with reference to international advanced technology and developed according to the current situation of domestic power distribution network. This monitor is suitable for AC/, rated working voltage, and is widely used in unit power supply systems of high-rise residential buildings in high-risk warehouses and power systems in gas stations, hotels, and densely populated buildings. It can effectively ensure the safety and security of electricity use. Prevent the occurrence of electrical fires.
2. Structural Principle
The monitor is composed of a shell, button, display, input and output interface combined with a high-performance microprocessor core. Various sensors and input and output interfaces perform a series of complex actions such as signal acquisition, processing and control. Various real-time information and control signals of this product can be read and controlled on the host computer through R communication. The monitor obtains the current power grid information through the sensor, and submits it to the microprocessor for calculation, identification and judgment. After verification, it is sent to the control circuit, and at the same time, the information is sent to the host computer and display screen for the operator to observe.
Three working environments
Temperature: ℃~℃ Humidity %
Altitude (after exceeding it, it is necessary to reduce the capacity and reduce the rated current)
Environment: No conductive dust, non-corrosive and flammable The gas is not directly affected by thunderstorms, avoid strong direct sunlight, avoid rapid aging of the LCD screen, and stay away from strong magnetic field interference. The magnetic field strength in any direction should not exceed times of the geomagnetic field.
Four usage requirements
Before installing and using the product, you should first read the instruction manual of this product to understand the performance and working requirements of the product
Monitors without outer boxes should be installed by non-electrical professionals and Keep out of reach of minors
The wiring of the product should comply with the specifications. The terminal screws must be tightened and fixed and must not be loose
Each interface line must be ensured to be correct to prevent damage to internal components or other consequences when connected incorrectly. Loss
When installing, be careful not to let foreign objects fall into the monitor
The working power supply should meet the requirements and cannot exceed or fall below the limit value, otherwise the product will burn or fail to work properly
After installation, test run System, pay attention to errors and abnormal conditions
Conduct self-tests on the detector regularly to ensure its operating performance

Eleven Troubleshooting
Residual current alarm: First, check the records on the monitor to find and handle the relevant faults The reset button can be used to reset. After reset, the monitor can be closed only when it is running normally.
How to display unconnected: Unconnected means that the transformer is not connected. Check whether the transformer wiring is stable, eliminate disconnection and other faults, and then restart or self-test the detector.
With backlight but no display: Make sure the use environment is normal and not in a place exposed to high temperature and strong magnetic sunlight. Disconnect the tripper and restart the detector. If the problem persists, please contact the manufacturer for replacement.
No backlight and no display: First, check whether there is any foreign matter inside the product, whether there is a burning smell in the product itself, check the terminal connections, and check whether the power supply meets the requirements. If the problem still cannot be solved, please contact the manufacturer.
Note: The manufacturer will charge a certain maintenance fee for malfunctions caused by human factors such as improper operation.
Twelve Precautions
It is strictly prohibited to disassemble this monitor without permission, otherwise our company will have nothing to do with any consequences arising therefrom.
The use and installation of this monitor must be operated by professionals. Be sure to read this instruction carefully before operation.
After the circuit breaker is tripped by a detector, the cause must be investigated and the closing operation can be performed only after confirming and eliminating it
Be sure to distinguish between the ground wire and the neutral wire. In the monitoring circuit, the neutral wire must pass through the transformer.
When selecting a detector, attention should be paid to whether the technical parameters on the detector are consistent with the requirements of the actual application.
Periodically check to remove dust on the surface of the heat dissipation holes of the casing, pay attention to the connection status of the terminals, and maintain reliable insulation.
During use, storage and transportation, it must not be subject to rain erosion, sunlight exposure or violent impact, so as not to damage the stability and accuracy of the monitor.
The alarm setting value of the monitor should take into account the normal leakage value of the power distribution system and electrical equipment.
