Hi,

OIC. tq
So, i notice that the led will turn off whenever the faultsignal is change BUT after a few milisec it turns ON back.
The problem on my design is that i dont know how much time the fault signal will be interrupted before it back to normal operation

What should i do if i want the led to turn off until the fault signal back to normal operation which 5V again?

any example for me?

photoelectric
