When the electric supply in the circuitry is higher than the limit set by W1, LED 2 will be lit, door 2 will be closed, output 1, J pulled in, closed contact is disconnected. That could realize the purpose of temporary protection to interruption. When the electric supply is lower than the limit, door 4 opened, LED 1 lit, the output of door 3 is 0 , J pulled in. That also could realize the purpose of temporary protection to interruption.   (View)
