What does it mean for different buzzer alarm situation on LF inverter?
1. Low voltage alarm: INV ON green light and red light will be on, with short alarm once every five seconds; there is an output, and the inverter does not turn off.
2. Low voltage shutdown: no light will be on with buzzer alarm, and there is no output.
3. High voltage alarm: INV ON green light and red light will be on, with short alarm once every one second, and there is an output; the alarm lasts about one minutes (57 times) then only INV ON green light will be on, still with buzzer alarm, and there is no output.
4. High voltage shutdown: after the inverter is turned on, the buzzer alarms, INV ON green light will be on for 10 seconds, then all lights will be off, and there is no put.
5. Temperature protection: INV ON green light and red light will be on, with 3 times of short alarm and later the buzzer alarms without output of the; then no light will be on, but the fan will be running; after the temperature drops, the fan stops running, and the inverter keeps alarming without output.
6. Overload protection: there are three levels of this situation: slight overload (the overload is no more 400w than the set load), INV ON green light and red light will be on without alarm, and the inverter is working without off; moderate overload (the overload is 400w-1000w more than the set load), INV ON green light and red light will be on with a short alarm once every one second, and there is an output; one minute after, the buzzer alarms without output, and no light will be on; heavy overload (the overload is about 1000w more than the set load), INV ON green light and red light will be on with a short alarm once every one second, and there is an output; 10 seconds after, the buzzer alarms without output, and no light will be on.
Note:If the LF inverter is not equipped with the function of automatic start after alarm and shut down, please switch off the inverter and restart it .
