After the lock body is installed and energized, the expansion and contraction of the bolt is very slow, and it feels weak? Is it normal after the battery is directly connected to electricity?
This phenomenon is caused by insufficient power supply voltage, and after the battery is connected, the voltage is restored to normal through the relief of the battery, but it is actually temporarily normal (this phenomenon will appear after the battery is exhausted)
It is recommended to deal with the following methods:
1. Please check the connection. 2. Or replace the high-power power supply. 3. Ensure that the electric lock voltage reaches DC12V and 1A current.
