Near Intersection of I-35 & I-90 Southern Mn.

I'm thinking they did this because the 460 controls the pwm valve through the aux cable. A 440 or 450 controls it from the main cable with all the boom sections. And so does your ezboom. Unfortunately switching that cable will not work. Only possibility is it's been jumped from pin 3 and 4 on the main cable to drive the pwm valve through your ezboom. Pins 11 12 and 13 are flowmeter on the main cable. Hope that helps


Your thought about controlling the PWM valve could be important. The PWM valve in certain Ag Chem machines requires a Heavy Duty PWM driver circuit. Raven built a model 661 controller for Ag Chem. It behaves like the other members of the family but had some extra features. 1) 10 boom capability 2) Granular capability 3) Heavy Duty PWM output on another pin. The 661 has control on pins 3 & 4 like the 440/450/460/660 AND a Heavy Duty output on a pin in the 14 pin connector. The idea was that this single controller could be put in any Ag Chem applicator.

The OP mentions that the rig currently has a 460 in it. If so and it works for control then the control pin(s) are not an issue. However it is possible that the 661 is needed and a substitute 460 was put in its place to make the sale. If the 460 is able to control the PWM valve then this "other" wire is not an issue, however section control is still questionable.

If the rig really needs the 661 because PWM control is expected on the pin in the 14 pin connector then EZ-Boom will likely have a problem. EZ-Boom will have pins in locations 3 & 4. Look at the mating connector on the sprayer side. If it has pins in locations 3 & 4 then control may not be an issue. If pins 3 & 4 are empty then look at the 14 pin connector. One of the wires there (don't remember which one) is used for the PWM control valve. EZ-Boom might be able to handle it if that wire were in effect moved by use of an adapter.

Here again this all relates back to the idea that EZ-Boom was made as a direct replacement for a 440/450 and NOT necessarily a replacement for other members of the family. Here again temporarily testing with a 450 would be helpful to determine if 1) section control can be accomplished with the built in Master and Section switches and 2) rate control can be handled with the 450 INC/DEC switch. If both conditions are met EZ-Boom will drop right in, otherwise some rewiring will be necessary.
