Posted 3/11/2020 17:48 (#8096645) Subject: Ag Leader ISO Pump Always Runs
Ag Leader Incommand 800 with ISO rate control. The control valve is a PWM valve and everything works great. Snaps to rate, primes right away, holds pressure with all sections off, and when agitating. The issue is that once I prime the pump the pump never stops turning until I turn the display completely off. In my mind the pump should shut down when I leave the run screen and return to the home page. However the only way to stop the pump turning is to unplug the pump or shut off the display. This could be an issue once no product is left in the tank. I’ve changed the PWM pins around, change the control valve type from PWM 12v to PWM ground, swapped the puns to the PWM, and the behavior is the same.
My plan is to run one of the wires that runs to the PWM through a switch in the cab so that I can manually shut down the pump if needed. Am I missing anything? Is this normal behavior?
