I add new water continuously to my sump and have an overflow to an extra container. I have one optical level sensor and would like to use it to start a pump in the container when the water reaches a certain level and have the pump run for a certain time. How would I program my profilux to do that?
Hi
i think this covers that in full :)

As far as I understand, that is a description for doing water change and using two level sensors? I want to trigger a pump for a certain amount of time (for example 1 minute) when my only level sensor registers water.
You are right, in the mentioned link you can find a description for AWC.
As I understand we are talking about a special kind of ATO.
For standard ATO (if level too low - water should be drained) you need only one sensor. Set the mode for this sensor to "ATO". Then assign to a socket the function "Water 1". That's it.
In your case - pump on for a certain amount of time when sensor registers water - the use of programmable logic is a possible solution:
1.) choose operation mode for sensor
select ATO
2.) Define logic 1:
function = delayed off
time = 60s
input = water 1 inverse (set inverse checkmark)
3.) assign socket
set function of socket in question to programmable logic 1
check if you time settings in the level sensor section are OK for your application
That sounds like exactly what I need. Do I understand correctly that the 60s delay will start when the sensor no longer registers water? If that's the case it's even better, the pump is sometimes slow to start because of trapped air.
Thanks for the help!
like you want: there is a "delayed off" and a "delayed on"
better you try what is better for your application
I see the problem: time overdue for sensor on is checked
->if you want to deacivate the alarm set the max on time to 0s
OK, I got it working finally. I set the max on time to 0s but it didn't help, as soon as I saved the correct settings the pump started even though the level sensor was above water. But after I pressed the reset alarm button and switched some other settings on and off it suddenly worked. Don't know exactly what did it. :)
it was the alarm - must be reset in order to get the level control working again
