Set/rest function

[gnisten]

I have earlier tried get information how to avoid a set/rest function eg. sr flip/flop to be reset after a reboot of the profilux or power faliure.

I use the function to avoid filling of my saltwater container for AWC, before the container is empty, the optical sensor at the bottom works as the SET and the optical sensor in the top as reset for this function.

BUT after a power failiure or reboot of profilux, the function is RESET, because the profilux doesnt remember the states from before the power outtake. Any suggestions how to avoid this

Hi

Can't you just invert the function?
Meaning the top sensor ist the set and the bottom sensor the reset. Then invert the pump output and it should work as before.
But after power failure or so the system stays in the correct mode.
