Nomad II issues

All my airguns and accessories seem to have sprouted issues over the last few days - most recently the Nomad II compressor. Guess when it rains, it pours ...

Anyways, I was filling up my Taipan Veteran (which I just got fixed from an issue it was having with cocking), when a fuse blew. Prior to the fuse blowing, I had the Nomad II fill the Taipan to 240 bar. Auto-shutoff worked, but I wanted to get 250 bar into the gun so I readjusted the auto shutoff to 250 and turned the compressor back on. At that moment it made a horrible noise and blew a fuse. I bled the pressure off, unplugged the unit from the power source and changed the fuse and tried to fill it again. As soon as I plugged the unit it, the compressor started up and made a constant electronic beep noise.

At this time the compressor is unusable. Compressor starts running as soon as you plug it in, and when you press the "on" button it makes a horrible electronic steady beep noise. In hindsight I should have bled the pressure off when it auto shutoff at 240 bar and I tried to squeek another 10 bar out of it. The manual mentions that if you don't bleed the pressure off prior to trying to refill it, the unit will "automatically stop after a few seconds of running". I wish it will tell you that their device will self destruct.

It's been a frustrating couple of days for me, and I'm really starting to miss the reliability that comes with powder burners. Between my two PCP airguns and my compressor I've had for a couple of months, I've had way more issues than I ever did over my 10 years of owning over a dozen powder burners. 
 
Watching the reviews for the Nomad II, I recall that having the unit auto-shutdown requires that the pressure already in built up in the unit must be drained off BEFORE hooking it up and starting the system up again. If you don't, you blow the mother board in the unit. I believe that's what you may have done based on your description of your failure. If you simply restarted the system after resetting the shutoff to 250 bar, but without depressurizing the unit, then you likely fried your mother board. Can't remember who, but there's a YT video out by someone who did just that. He had to get a new board from Air Venturi and install it - he notes that he has the skill and tools necessary for the fix but it's unlikely many others will be able to do the same. Sorry to be the bearer of bad news, but I think a trip to the manufacturer for refit is going to be needed.

That’s the way with all compressors, right? My Hatsan Lightning, if I try to start it up without purging the air thats pressurized, say into a tank top off, it won’t budge. It goes thru a fail safe mode, by this voice telling you it’s ready or not ready to go. At the two times I accidentally tried to turn it on pressurized, no voice comes on to tell me it’s okay to start. I’m sure I got lucky, by having no damage, and I vowed never to do that again.



Thats why it has auto purge, while running, to bleed off any moisture and not cause the compressor to lock up.

@Kthomas - Give Jordan a call at AV. He is the compressor guy. They'll probably have to get you a replacement unit. Give him a call between 1:30pm and 2pm if you can. If not, call and leave him a message earlier and he should get back to you this afternoon. If not, the retailer you purchased it from should be able to get you an RMA and replacement order set up.

Dude. It's not a flaw design. All compressor when already have pressure in the line will not and can not start. You already have pressure in the lines and you try to restart without bleeding. The Piston will try to force it while under pressure and most likely it will kick the breaker, blow a fuse, break the high pressure piston, and can damage it. It isn't a defective product. It's a user error. Why did you try to start it with pressure in the line? I know you reset the auto stop but you must bleed the lines. Call AV and see if it will cover in the warranty. Cause usually user error does not cover. Example my fx impact clearly says on manual it does not cover warranty if I screw the regulator in while under pressure and break the reg. Good luck man. Next time read the manual first. I'm sure they state it in the manual. Also I seen many people say bleed it first before restarting it on YouTube. Watch some YouTube video if you don't know what you are doing. It helps.

My new one won't let me restart the compressor once it goes through auto-shutoff....even if I bleed the line. I have to power it off and back on to start a new fill cycle.

Unless it's different if you manually power it down. Maybe I'll try that next time.

Bob after seeing this I retract my Instagram question about the burst disc. Was this power reset issue from the get go or did it develop over time? The fact that it had to be powered off then back on makes me think that the reset function logic, perhaps on the motherboard, is/was a bit wanky and required the power reboot to clear it. When we last spoke you said the unit would "run normally" but wouldn't pump air, I take it that was subsequent to the power reboot issue? 

I havent had a chance to use mine as yet so I'm a bit curious about the long term performance. I'll thank Air Venturi in advance for a nice long warranty period though.

Got my nomad back in june 2019. It has been working fine. I have just over 30 fills on a coyoty then all at once I get L. For low power. These have a switching type LED s-600-12 12v 50A switching power supply. It is like the MEAN WELL kind. Mine is out. It ran fine on the last fill then done for the next.

One half of the push pull power transistors is bad. It is making 9.3 vdc at idle but when turned on it drops to 6.2 vdc. Classic of a bad transistor. The machine works fine on the DC hooked to a battery. This is my line of work. My hope is being only a few months from buying this is that I can get threw to them and they will send a power board out. It is not too hard to replace. Half hour at most. Will update once I have resolved this.
