use dosing pump depending on the conduct censor

[peter_b]

Hi
I'm trying make my dosing pump run on a schedule but only if the conduct censor under a certain level.

I have tried:
step 1 dosing pump react to a switch channel.
step 2 set the assigned switch channel to manu. dosing and created my schedule
step 3 set a programmable logic to "AND" input 1 "conduct increase" input 2 " Assigned timer"
Have also tried set it to descrease and alarm.
But what ever the conduct censor is reading. the dosing pump always start on the schedule in the timer.

That am I during wrong?

How do I get to not start dosing if conduct is at the desired level?
