Near Intersection of I-35 & I-90 Southern Mn. | I'm surprised this is happening with only 1 or 2 booms ON. Raven and Ag Leader are both flow based and do not "watch" the pressure so setting a low limit based on pressure would not work.
They are both flow based so setting a low limit based on volume/minute is used. The system will not drop below this volume in automatic so as to prevent tip check off or a poor pattern. On Raven at least (and I thought Ag Leader also), the value is factored down based on the booms that are really ON.
So if you had a low limit of 14 gallons/minute set in, the system would never drop below 14 GPM with all booms ON. If only half the total width was ON, the effective low limit would be 7 GPM. I know the Raven behaves this way and I thought Ag Leader did also.
So if all tips come on at a crawl with all the sections on, I would think it should continue to work with only 1 or 2 ON since the limit has been reduced. I have not really tested my Ag Leader system under these circumstances. I do not have flo-bak valves, mine are standard TeeJet ON/OFF ball valves. |
