< One main purpose and scope of use
< Split residual current Electrical fire monitoring detector is developed and designed by our company in strict accordance with the national standard B "Residual Current 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/DC power distribution circuits with rated working voltage and rated working current. It is widely used in unit power supply systems of high-rise buildings and residential buildings in high-risk warehouses and power systems in gas stations, hotels, and densely populated buildings. , can effectively ensure the safety of electricity and prevent the occurrence of electrical fires.
< 2. Product Structure and Principle
< The monitor is composed of a shell button display input and output interface combined with a high-performance microprocessor chip. The display screen and buttons play the role of human-machine dialogue, and the LCD display customized according to the focus of the display is more concise and clear. Various sensors and input and output interfaces perform a series of complex actions such as signal acquisition, processing and control. All kinds of real-time information and control signals of this product can be read and controlled on the host computer through R communication.
< 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 easy to Combustible gases should not be 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 the product to understand the performance and working requirements of the product
Monitors without outer boxes should be installed in non-electrical majors Places that are out of reach of persons 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 damage to internal components or damage if connected incorrectly. Cause other losses
During installation, 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 be burned or not work properly
After installation Trial 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

Eleven installation, use
<, understand
Please read this instruction manual carefully before installation.
<, Installation
Install the monitor on the panel of the distribution box or on the guide rail inside the box, and fix the residual current transformer at a suitable position in the box so that all outlet terminals of the molded case circuit breaker are connected from passed through the transformer.
<, Wiring
Monitor power lines, control signal lines, and tripper output lines can all choose RR or higher specification twisted pairs.
The monitor should draw power from the incoming end of the molded case circuit breaker. Take any phase B and connect it to the power port (port No.), and connect the other phase to the power port (port no.).
The transformer should be connected to the corresponding transformer input port according to the monitoring loop, without polarity distinction.
Release output: Corresponding to the monitoring circuit, connect any phase B of the outlet terminal of the molded case circuit breaker to any one of the tripping output terminals of the monitor, and lead the other end of the tripping output to the shunt tripping The trip coil of the molded case circuit breaker is connected, and one end of the trip coil is connected to the neutral line outlet of the molded case circuit breaker to achieve trip control. (Note: All tripping outputs of this product are contact passive outputs and only provide breaking function. To achieve shunt tripping, power must be introduced)
Alarm output: The alarm output of this monitor is passive relay contact Output, with normally open, common and normally closed points, connected according to the requirements of external alarm.
Fire linkage input: Obtain the linkage signal from the fire host, connect the positive pole to the monitor port, and connect the negative pole to the monitor port to achieve remote forced cutting control of the circuit breaker switch through the monitor.
R communication: Connect the monitor’s port number to the bus number line, and connect the number port to the bus B number line. All monitors do not have matching resistors inside, so when the number is large and the distance is long, The end of the communication line should be externally connected with an ohmic matching resistor between the bus line and the B line. If a shielded communication line is used, only one end of the shielded line needs to be grounded.
, test
The wiring of the detector should be confirmed before powering on the detector, and the fixed connection part should be kept firm. After powering on, attention should be paid to checking whether the tripping action of the detector's audible and visual alarm display device is normal. It can be put into use only after it is correct.

The meaning of each code is as follows:

< Press the Cancel key after all setting and viewing operations are completed Twice, the system will exit the menu and return to the normal operation monitoring interface.
The silence key is used to cancel the audible and visual alarm status and restore the trip output relay.
The self-test button is used to re-test the connection status of the transformer and the action status of the alarm trip output. The self-test will cause the tripper to operate. Be sure to pay attention to the load connection of the circuit breaker when using it.
Note: This monitor uses the R communication method, and the communication address setting cannot exceed
When setting the password, the numerical range cannot exceed
< Fifteen Precautions
It is strictly prohibited to disassemble this monitor without permission device, otherwise all consequences arising therefrom will have nothing to do with our company.
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 the 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.
