Hi,
I have a basic sump tank with a hi level float and a lo level float. I want to control the level of this sump using a pump that is pumping out. I'm using RSlogix5000.
I would like to latch the output on when the system is in auto and the hi level is reached, so I have programmed as such. I want this system to unlatch when the low level is reached. Easy enough.
The problem I have is when the operators put this system in manual sometimes the water level goes past the low level float basically(NO contacts). I need this swt to be ignored as the water rises because the bit will change states and then once the swt opens back up(XIC green) then it triggers and unlatches pump. Could I use a OSF in this case and if so what do you use for the storage bit and output bit.
Second, I could make this a one float control using time, but the time could get sketchy depending on the amount of flow coming into the sump. Any thoughts.
