redstone input

im tryed for like 4 hours to get this to work but i cant
now im asking how do i get the reactor to stop running when its turned on when the mfsu is full it sends a purple redstone signal if its full
becouse i only got it a bit to work when i have pull event restone but i dont want it to pause i just want is to do somthing whenever a redstone sigal comes in

1 other thing i want is if redstone input purple is false then then reactor is on when redstone signal is true the reactor turns off and i need it to work whenever a redstone signal goes in i also tryed this for long time to get the nuclear reactor turn off and on automatically but i could get it to work
so if somone could show me how to do it thx

Truely, I am sorry. I'd love to help you, but I cannot understand your grammar. Please fix it and I'll try again.
