Near Intersection of I-35 & I-90 Southern Mn. | First let's make certain that I understand the situation. Here's my understanding: In the past this bar was run with a Raven system using a Fast Close valve (handles both Master ON/OFF and control) with 3 ON/OFF section valves.
You are changing it to Raven Standard Control consisting of a Standard (Slow) control valve and a Master ON/OFF valve which lead to the 3 ON/OFF section valves. You will have a grand total of one Standard Control valve followed by a Master ON/OFF valve from which the flow splits and leads to 3 ON/OFF section valves. If this is not correct the following information does not apply. You mention something about using the Boom 6 pin on the Boom plug, this is not correct. Boom 6 may have been used with some Raven systems. The Ag Leader system does not handle the Master ON/OFF valve that way.
The Fast Close Valve needed Power, Ground and an Increase and Decrease pair of wires. The Fast Close value needed constant Power and Ground because it is not "geared down" like the Standard Valve therefore it needs more power to turn the ball quickly. An internal driver circuit board handles this.
The standard control valve does not need the Power and Ground wires, it only need the Increase and Decrease pair. It does not need the driver circuit board. That means of the four wires that had gone to the Fast Close valve, only the Increase and Decrease pair from the Liquid Module need to go to the Standard Valve.
The new ON/OFF valve will need 12V constant Power and Ground. It will also need a trigger wire. The 3 section valves should already be getting Power and Ground. Their trigger wires are the Black, Brown and Blue wires I can see from you picture leading to the Boom connector on the Liquid Module. You show a circle where a Boom 6 wire could be attached. This is not correct.
So, the Increase and Decrease pair from the original Fast Valve will now go to the Standard Valve, The New ON/OFF valve will need a power and ground source, the 3 section valves are fine the way they are.
The only thing that remains is the trigger to signal the Master ON/OFF valve to open. This trigger is taken from a pin on the black connector that has the implement switch stub which might be connected to a real implement switch or a jumper. Their are two pins on that connector that can be used for Auxiliary Valves. Each can be programmed as either a Master ON/OFF valve or a Master Dump valve. I don't recall the pin number(s) off hand but you will want to put a pin in the first location and run a wire to the trigger for the Master ON/OFF valve. Then in the configuration inform the system you want it to behave as a Master ON/OFF valve.
When set as a Master ON/OFF valve, the system will send 12V out on the the trigger wire if any of the section valves defined in the configuration happen to be ON. It will not send out 12V, if all the section valves are OFF.
So in normal operation, the operator or auto swath will decide which of the 3 sections should be ON. If any section goes ON, the system will trigger the Master Valve to Open thus providing flow beyond the Master Valve. Let's suppose all sections are ON and you reach point rows, auto swath or the operator will shut off a section, the rate will be temporarily high and the system will close down the Control Valve somewhat to apply the correct rate to the remaining sections. As you progress more into the point rows, auto swath might cycle off another section which again temporarily results in over application so the system closes the control valve a bit more. When auto swath decided to shut off the final section, the trigger to that section drops to zero and the trigger for the Master ON/OFF valve also goes to zero. This stops the entire flow out of the system. As you turn around and proceed back, the reverse process may take place. That is once a section is turned ON, the Master valve will Open and the Section valve(s) as appropriate.
You may be curious as to the purpose of the setting for a Master Dump Valve. This setting can be used in those situation where a positive displacement pump is used. Those systems may have a Master Dump Valve that should open when all the section valves are OFF or closed. This would not apply to you.
You ask about the boom widths. Boom 1, 2 and 3 will be programmed with their actual widths as they would be with a sprayer. There is no width associated with the Master ON/OFF valve since it is triggered internally only when a section valve is ON.
This may seem confusing but works well. When using a Raven 440 or 450 with such a system, we often created a trigger wire for the Master ON/OFF valve by splicing a diode on to each of the section trigger wires and connecting the ends of the diodes together and soldered on a piece of wire. This new extra wire lead to the trigger of the Master ON/OFF valve. Since the diodes act as a one way valve, they would pass 12V onward if a section was ON. This meant the new wire was 12V whenever any section was ON but was 0V when they were all OFF. Some folks handled this a different way but the diodes worked well. Ag Leader has done the same thing with internal programming rather than using actual external diodes like we did.
