I am looking for a solution to make the pump start when the high level is reached and until the low level. Then it would start again as soon as the high level is reached and so on. There must be an easy solution, but after spending hours looking for it, I can"t find it. Thanks in adavance. Gadz

Gadz Dear member, check if the solution suits your case [code] A I 0.0 //high limit,true when level high L S5T#1S SD T 0 NOP 0 A T 0 A I 0.1 // low level, false when tank is going to be empty S Q 0.0 //start the pump NOP 0 AN I 0.1 L S5T#1S SD T 1 NOP 0 A T 1 R Q 0.0 //stop the pump[/code] Best regards

Is it possible for you to explain me exactly what the program you propose me means, or how to do it in CONT language? Thank you, Gadz

Dear Gadz Check the LAD version, the only point worth mentioning is using on delay timers to test binary signal to be steady for at least 1 second! Best regards Attachment LAD.zip (229 Downloads)
