Controller Panel Structure
1.LCD display screen
2.Curve LED
Red LED indicators are hidden in the curve. When a fault occurs, the corresponding LED will flash, indicating the fault type. When setting the protection parameters, the corresponding LED will be constantly lit, indicating the curent item under setting.
3."Working"LED——The green LED always flashes as long as the controller is powered on and in normal working condition
4."Fault/Alarm" LED——During normal operation, the LED is not lit; during the fault tripping, the red LED flashes rapidly, in the event of an alarm, the red LED is constantly lit.
5."Communication" LED-Modbus——During the communication, the LED flashes; when theres no communication the LED is not lit.
6."AP" LED-advanced protection indicator
( in the event of fault tripping due to phase loss, over-voltage, voltage unbalance, under-frequency, over-frequency. reverse power, etc., the"AP"LED is lit if alarm only no tripping.)
7."Up"button——Move menu content upward in the currently used level, or increase the selected parameter.
8."Back" button——Exit the currently used level to go to the upper level menu, or cancel selecting the current parameter.
9."check" button——Function button 2, used for the cycle switching, between"System parameter setting menu"and"History and maintenance menu". in password inputting interface, this button works as"Right" button.
10. Down"button——Move menu content downward in the currently used level, or decrease the selected parameter
11."Enter" button——Go to the next level menu pointed to by the current item, or select the current parameter, or save the modifications made.
12."Test" button——Once pressed, the tripper trips one time, used for testing whether the mechanical mating is normal
13."Reset"button——After fault, the LcD screen shows fault. After troubleshooting, you need to press this button to reset the display
14."Set" button——Function button , used for the cycle switching between"Measurement menu"and "protection parameter setting, menu. in password inputting interface, this button works as"Left" button.
FAQ
1. What is an ACB (Air Circuit Breaker)?
An ACB (Air Circuit Breaker) is a protection device used in low-voltage power systems. It can quickly cut off the current when a circuit fault occurs, protecting equipment and personnel from electrical hazards. It uses air as the medium to extinguish the arc, making it a commonly used switching device in electrical systems.
2. What is the difference between ACB and MCCB?
Both ACB (Air Circuit Breaker) and MCCB (Molded Case Circuit Breaker) are used for protection in electrical systems, but they are suitable for different current ranges. ACB is generally used in high-power, high-current electrical systems, while MCCB is suitable for medium to small-sized electrical systems. ACB has a higher rated current, usually used for applications above 500A, whereas MCCB is typically used for lower currents.
3. What is the working principle of an ACB?
The working principle of an ACB is based on the air medium arc-extinguishing principle. When a circuit fault occurs, the contacts inside the ACB open, and the arc forms in the air and is quickly extinguished. To prevent the arc from causing a fire or damaging equipment, the ACB is designed with a forced air cooling system and arc-extinguishing devices to rapidly extinguish the arc.
4. What are the additional requirements for the high-voltage version of W3?
The insulation and heat dissipation requirements required for high-voltage operation have been fully considered during the design of W3. It is recommended to follow our installation instructions during installation to ensure that the use environment meets the corresponding safety spacing and ventilation conditions.
5. Are the warranty and after-sales service of these three products the same?
Yes, W1, W2, and W3 all enjoy the same warranty period and perfect after-sales service. For specific warranty terms, please refer to our "Product Warranty Policy".
6. How to choose the product model that suits me?
You can choose according to your installation environment, electrical parameter requirements and budget:
a. If you pursue maturity, reliability and strong versatility, choose W1.
b. If you have high requirements for space and weight, choose W2.
c. If you have high requirements for voltage level and performance, choose W3.
d. If you need help, please contact our technical support team and we will provide you with selection suggestions.
6. Are the warranty and after-sales service of these three products the same?
Yes, W1, W2, and W3 all enjoy the same warranty period and perfect after-sales service. For specific warranty terms, please refer to our "Product Warranty Policy".
