Have a new Generac 22kw generator just installed.  When I push the automatic operation button it starts and switches the ATS to generator power as if it is operating under the manual button.  It appears to not recognize the presence of utility power.  What would make it do this?

Blown N1 and/or N2 fuse in the ATS is the first place to check.

Also, check if the N1 and N2 control conductors were even installed.  If the control wiring is present and the fuses in the ATS are good, then check for 240V at the N1 and N2 terminals in the generator.

I have seen the N1/N2 wires pushed into the stab connections at the generator and the insulation on the wires was keeping them from conducting.

Thank you for the suggestions.  I now have some things to check on.  A little more info:

I had an electrician install the ATS panel and all of the electrical connections.  However, I installed the battery and cold weather kit (oil filter warmer and battery warmer pad), activated it online (Evolution 2.0 controller) and fired it up for the first run.  When installing the leads for the CWK I did not totally disconnect all utility power and had a little spark from the N1 when I hooked up the CWK line (woops - won't do that again). That could have blown the fuse in the panel, so will be checking that.  Will also unplug the CWK lines at the connections and see if that does anything and work my way through the list.

There was one spare fuse in the N1, N2, T1 block in the service panel.  The fuses have solid white bodies -- is there a way to check if they are good before I go buy some?  It is a 50 mile trip to town or order online for fuses.

I think you blew the fuse, use an ohm meter to check the fuses, take them out of the switch to test. You wont find those in town unless you have a Generac dealer that stocks some parts.

Those fuses are a pain to find anywheres. I ended up ordering 20 from generac when i placed an order. Leave it to them to make a fuse no-one can locate. Im sure you blew fuse.
also, be REAL careful pulling out those fuses and re-installing them. You can easily bend the tabs. Theres a fuse insertion tool attached to block below fuses. There not easy to install.

I've had great luck with Amazon on the fuses.  I ordered 6 extra and placed them in the ATS.  I put a label on the ATS that there are extra fuses.  I also included the automotive type fuses (extras) in the ATS as well.

Thanks everyone.  Found some fuses online for $2.30 a pop and ordered them.  Had a PM with a link for 25 fuses for $9.27 . . . after I placed the order.  Will report back once I get the problem solved.

It's always nice to have extra's.  You don't need 25, I've never had to replace one.  And for the most part, the only times I've heard of them really getting blown is usually pilot error.  They should not go poof on you.

I have replaced fuses over the years. Some from lightning, some from power surgers, alot from bad battery warmers.

N2 fuse turned out to be the problem.  Replaced it and we are on automatic standby now.  Thanks for the help.
