OK, I can't see half the data on the sensors, and of course the programmable logic.
I guess you do not want to use any of the AWC functionality and doing this completely manually.
Do you have a level card installed as you seem to have level sensor 5 selected as 1 of the sensors?
But this may work.
Programmable logic with input 1- timer (or digital signal or maintenance button) input 2 - Fill Water (which ever number the level switch is on?) SR-Flipflop for function.
Select this programmable logic as drain pump. ( This will turn on the drain pump until it gets another signal which would be the fill water signal.
The level switch make a fill command when the level drops and it will be delayed by however long it will take to drain the sump (tank) with the end of the delay the fill pump will come on and shut of the drain pump.
The set for the SR logic is always timer, so it can't start draining by the level control asking for a fill.
This will leave all your current PL's as they are.
I have not tested it, so make sure it works by playing with the various sensors and low time values initially.
Maybe what you are looking for??
Let me know if it works or not and I can have a closer look when I have time.
