Installed it 6 months ago and owner noticed not exercising. Any ideas?

1. There is a separate gas reg, 5' from gen. Ad its lp...

Try this, check the connector on the oil pressure sender. Found a couple of these loose lately. Same 8kw/Evolution controller. Had to lightly crimp the connector so it would stay on. These would just barely start and then quit. Same error code.

manually run the unit and see if you still get the rpm sensor loss.

I tried starting 4 times after resetting alarm. It would run for like 3 seconds and then show same alarm.... I saw about hi gas psi online and had owner turn on all other gas appliances, and it started... Tried it Repeatedly and worked every time! I simulated loss and ran and xfered like it should.

Wtf?

Gas pressure would have to be measured to see whether it's out of the 10-12 inches of water column. This connector problem can be intermittent.

Unfortunately im no gas guy... Lp co is coming to check, as i didnt connect gas... Is this hard to check gas? What tools needed?

You should check the water columns to see if they are within operating pressure

allen wrench and a manometer

I'm no gas guy either. Just need basic gas manometer and you remove one of the two plugs on the regulator and screw in a brass nipple with a barbed fitting . Rubber hose connects to the barb. One port is before the solenoid, the other is after.

$40 bucks and you can check the gas pressure yourself..and no messy water or other liquid columns to deal with. :thumbsup:

I got another similar one from another supplier and used it to set up my propane lines here.

Fuel water columns should have been checked at install. The error code shown on the controller is not related to fuel pressure.

 

[nrp3]

I agree, but sure enough that code directs you to tests 50 and 64. Fuel and coil ground wire.

Go to zillerstore.com/forums/ for extensive Generac discussion and support. for example, I've see a recommendation there for more distance, about ten feet from the secondary regulator.

 

[nrp3]

Good site. On that as well.

Forgot to look at the $500.00 manual. It defaults fuel pressure issues to RPM sensing. Test 50 ,check water columns .

Not $500 but not cheap either. I don't do electronic copies. Like my paper based texts. Sometimes the tests lead you down the garden path and you miss the more obvious mechanical issues like a head gasket. Or maybe not so obvious. Been and still a new learned skill.

suppose to be an updated manual coming out in the spring

Was scratching my head on some of the new connector pin outs the other day. Likely some corrections needed for the new controllers.
