< A main purpose and scope of use
The integrated residual current electrical fire monitoring detector is our The company develops and designs strictly in accordance with the national standard B
"Residual Current Electrical Fire Monitoring Detector". Designed with reference to international advanced technology and developed based on
the current status of domestic power distribution network, the new residual current electrical fire monitoring detector (hereinafter referred to as monitor
for short). This monitor is suitable for AC/, rated working voltage, rated working current
power distribution circuits, and is widely used in unit power supply systems of high-risk warehouses, high-rise buildings, residential buildings
and gas stations, hotels and densely populated areas The electrical system of buildings and other places can effectively ensure the safety of electricity and prevent the occurrence of electrical fires.
< 2. Product structure and principle
The monitor is an integrated fire monitoring detector, which combines the traditional leakage circuit breaker with the currently commonly used split
integrated fire monitoring detector into one. While ensuring the convenience of installation of the traditional leakage circuit breaker, it can fully demonstrate the advantages of the digital residual current monitoring system such as fast, accurate, efficient and easy maintenance. This
monitor has a built-in high-precision residual current transformer, combined with a high-performance microprocessor chip, to collect the residual current
value in real time and display it on the digital tube. At the same time, it can be controlled through the communication bus. Background monitoring.
Altitude (after exceeding it, it is necessary to reduce the capacity and reduce the rated current)
Environment: No conductive dust, non-corrosive and flammable Sexual gases are not directly affected by thunderstorms. Avoid strong
direct sunlight to avoid the rapid aging of the LCD screen. Stay away from the interference of strong magnetic fields. The intensity of the magnetic field in any direction should not exceed 3 times 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 operation of the product
Requirements
Monitors without outer boxes should be installed in Keep out of reach of non-electrical professionals and 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 internal damage when connected incorrectly. components or cause other losses
During installation, care should be taken not to allow foreign objects to 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 be burned or not work properly
After installation, test run the system and pay attention to errors and abnormalities
Conduct self-tests on the detector regularly to ensure its operating performance
< Five product features
□ Digital tube display, simple and intuitive
br /> □ Integrated design, simple and clear installation and maintenance
□ Equipped with both residual current detection and temperature detection functions
□ The product can operate independently, complete all functional requirements, and can also be networked for monitoring and linkage alarm
br /> □ The residual current alarm value of the detector can be set arbitrarily in ~
□ Using fieldbus communication technology and industrial standard b communication protocol
□ The event automatically stores and records the last alarm value

Confirm the product The appearance is complete and there are no foreign objects inside before connection and powering on
Use the self-test function button to observe whether the sound and light are normal. At this time, you should also pay attention to the digital tube display parameters. The system
will display when normal. If the internal If a transformer appears and the tripper connection is disconnected, rr will be displayed
After rr appears, this product should contact the manufacturer for processing
The on-site parameter setting detector has a total of five available buttons and their functions are as follows

< < < When selecting a detector, you should pay attention to whether the technical parameters on the detector are consistent with the requirements of the actual application.
Periodic inspections should be carried out to clear the dust on the surface of the cooling 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.
