The fault arc protector, hereinafter referred to as the protector, effectively detects the fault arc in the access line, including the fault parallel arc and the fault series arc. When it detects that there is a fault arc that causes a fire in the line, the outlet power-off function can be carried out to achieve the purpose of warning of the occurrence of a fire.

Product interface description
*Note:
① When the product is in alarm mode, the detection function works normally.
② When the product is in the alarm indication, the alarm needs to be lifted before the unlocking experiment can be carried out.
③ After turning off the arc detection function, the leakage function can work normal
Operating instructions
1. Operating indicator (green), when the product is powered on and running normally, the RUN indicator light is on, indicating that the faulty arc function is turned on.
2. Leakage indicator (red), when the product is separated due to leakage failure, the next time the gate is closed, the leakage indicator light will flash the alarm, and the alarm will be automatically lifted after 60 seconds.
3. Arc indicator (yellow), when the product is separated due to an arc failure, the next time the gate is closed, the arc indicator light flashes to alarm, and the alarm will be automatically lifted after 60 seconds.
4. Product reset. When the product is disconnected due to an arc or leakage failure, the R button will pop up, and you need to press it to close the gate.
5.Detachment experiment. When there is no alarm, press the "T" key, and the product will be subjected to the unbuttoning experiment to verify whether the product's unbuttoning function is normal. When the product is in the leakage or fault arc alarm indication,
Press and hold the T key for 2 seconds to forcibly release the alarm indication.
6. Query and switch the working mode of fault arc. Press the SET key for a short time to query the current working mode. Press the SET key for a long time to switch between 4 modes. At this time, the RUN light flashes.
The number indicates the working mode (please do not adjust it if it is not necessary).
Ø Flash 1 time: disable mode. At this time, the arc detection function is turned off, and the RUN running light will be turned off.
Ø Flashing 2 times: anti-interference mode
Ø Flash 3 times: standard mode (default)
Ø Flashing 4 times: hypersensitive mode
