Now wWhen start button is pressed, the chemical pump should start and run (Q3=1)till the set.
When the count of flow meter pulses,reacheswhichispulses are connected to a counter, reaches the counter preset, at which point the chemical pump stops (Q3=0) and the water solenoid valve opens (Q2=1), and w.
When the water reaches the high leveltanksensor, thehigh level sensor should stop thewater solenoid valve should close (Q2=0)., w
When the water goes below the high level sensor, it should not turn on the water solenoid valve (Q2 remains 0).
The process shouldstsrtstart again when the water reaches the low level sensor.
This is the modified program, but is not working based on your logic, i have explained how i want it to wort in my previous comments, but if you are still nor clear, tell m, i will explain further
It is still not working, when Q3 is off, Q2 needs to come on, and that can only happen if I3 is NC, but when I3 turns to NO, i do not want it to affect Q2 by turning it off. thanks
It is still not working, when Q3 (do you mean I3?) is off, Q2 needs to come on, and that can only happen if I3 is NC, but when I3 turns to NO, i do not want it to affect Q2 by turning it off. thanks
the water reachesing the high leveltanksensor,the high level sensorshouldstopclose the solenoid valve i.e. it should write a 0 to Q2,
when the water goes below the high level sensor, it should notturn onopen the solenoid valve.
the process should stsrt again when the water reaches the low level sensor/
@mylespetro: close valve at high level; open valve at low level. you need to swap I6 and I3, but you got it.
@koloyewo needs to better understand the Start/Stop Circuit pattern (e.g. here), NC contacts, and NO contacts; apparently, so do I :
No need to apologize, @koloyewo uses inconsistent and/or incomprehensible descriptions (e.g. "stop the solenoid valve"), and also makes many typos, regarding tag names and what they do, in almost every one of their posts. Not that my posts have been any better LOL. OP's flag is UK but it appears we are separated by a common language.Sorry, I'd misunderstood that Q2 was a pump.
