Subject: 750 Field IQ controlling Rogator PWM valve


Harvard, NE
When leaving a sprayed area the pressure drops to 0 then slowly recovers to normal. This only happens in auto not while in manual. Valve calibrations have been done several times but it does not help. It makes no difference if the valve is set on lock in last position or lock at minimum. There are many valve settings to mess with however I have no idea what they do. Can someone tell me which setting would help stop the PWM valve from shutting down when leaving a sprayed area? Choices are: Integral Gain, Minimum Response, Allowable Error, Boost (Feed Forward), several more under Advanced Tuning: Process Gain, Smoothing Factor, Upper PWM Limit, Lower PWM Limit, Comparator Limit, Differential Gain, Ramp Limit, even more under Advanced PWM: Base PWM Frequency, Dither Frequency, Dither Amplitude, Dither Control. Thank you
