Near Intersection of I-35 & I-90 Southern Mn. | Part of the problem with a Rogator that was or is equipped with a Raven 460/661 is the boom switch wiring.
This problem would be common whether you were trying to use Ag Leaders Direct Command or EZ-Boom.
This problem occurs because the Rogators typically utilize their own built in boom switches and Master switch. Other sprayers that use their own built in boom and master switches often have this same problem.
In many of these sprayers, the boom wiring flows something like this: electricity from the Master switch is connected to the input sides of the boom switches. The output from the boom switches split and flows two directions. It flows to the boom valves themselves (to trigger them to open) and also flows back into the Raven 460/660 to inform the Raven console as to which booms are currently ON. This is necessary so that the Raven can perform its calculations correctly.
The trick on these sprayers is to intercept the wires going to the boom valves and reconnect them to the output from the Liquid Control Module in a DC setup or something similar in an EZ-Boom arrangement.
It is possible to utilize the original boom switches as inputs to the AIM on an Ag Leader system with some clever manipulations or in other cases to use Ag Leader's switchbox. Problems can creep in with using another switchbox if the original switches happen to get turned ON. This can causes backfeeding and trigger booms ON inapproriately.
PWM control on certain Rogators is a separate issue but can be done with a DC setup. I have no experience with EZ-Boom and apparently the firmware there cannot work with PWM control valves.
We have installed a DC system in a PWM Rogator where we were able to utilize the original boom switches and master as inputs to the AIM module. It was also possible to use the Liquid Control module to run the PWM control valve. This sprayer had been running with a Raven 661. By means of a jumper, the 661 can be returned to service in this unit if the Insight is used elsewhere.
We made custom wiring harnesses to accompish this. This does require a pretty through understanding of the original wiring scheme.
