I have just bought a new sprayer and has been commissioned today but I have to wait for the Trimble technician to return from holiday.

Being impatient I have had a go my self. I have set every thing as per instructions and the ez boom and sprayer controls seem to recognise each other but I keep getting vale open error or valve closed error.

Do you run the sprayer box in manual mode or auto mode? The sprayer is a Berthoud Tracker.
