Amaspray+ and UF901

[shakalakka]

Hi,

Just breaking in a new UF901 with the Amaspray+ control box on a Fendt 516. Wheel sensor working, amaspray is showing the correct speed, ive input 200 liter/hectar, but for some reason the pressure is 4 times what it should be (2 bar for this application/nozzle, and it peaked at 8.3). One problem that i cant figure out is the "Hand mode" is on - and i cant get it to shut off. Its probably not helping to be in manual mode? The dealer wasnt really helpful - any thoughts? I did manage to manually steer the pressure with the down-button, but it didnt seem very stable.

The manual mode - hand button should toggle on and off when pressing it.

Nothing happens when i press it. I turn the box on, and the hand comes on after 5-10 seconds, and i cant turn it off. Do i have to be in active spray-mode?

Check the imp/100m button, If you’ve set that value to 0 by mistake it won’t let you change from manual to auto mode

Ah thanks - the manuel mode would explain the pressure-problem right?

 

[Gwj]

Correct, with the hand lit up, sprayer regulates via pressure, without it regulates via flow

Thanks a bunch, farmingforum always more details then the manuals..

No problem. I ended up swapping amaspray terminals for the same issue then found that out by accident

 

[shakalakka]

Haha i was about to too

My thoughts are if you've bought a new sprayer, the dealer should damn well be interested in getting it working properly. I would play hell with the firm, but I'm glad you are now sorted. I've got an Amazone sprayer and I think it is great!

if the speed readout was correct on the amaspray then it can't be the imp/100m setting. maybe imp/l or the width/sections settings - all yellow buttons. when i got mine, all these were set from the factory and the flowmeter even had the value written on it with a marker (for imp/l)

check the connector for bent pins and make sure it's a good connection

Now I’ve the same problem after resetting impulses. Cannot get hand button off and the amaspray box has dropped everything. All info gone.
