Generac Generator question...

My guess would be the ATS is detecting what it considers an under-voltage problem.... it's looking for 240 and sees 208.


• If utility source voltage drops below about 65
percent of the nominal supply voltage, the sensor
energizes a 10 second timer.

so 240v x 65% = 156, so 208 should be fine.

If your not a Generac / Guardian dealer I don't think you will be able to talk to a factory tec support. They allways ask for dealer dealer account information if I call them for anything. Non dealers get refured to local installer dealers. I have not been impressed by the tec department. Seemed like I get a part time student / worker sitting at a PC answering the phone.

That's when people like me get a phone call like this:

We bought this unit at the box store because they had the best price and had someone elce install it. It does not work... Can you tell us how to fix it? Or can you come out and repair it under warrenty (and get paid what the factory decides a few months later after several phone calls)? That's when I say sorry we're booked up for months and I can't fix it over the phone.


I'm not jumping on you, I figure you did a fine install. Just saying don't expect much from the factory.
 
I did this same install with the 13KW version(120/208 3ph building and 120/240 genset), did not cause a problem.

i'm not going to the factory....one of the supply houses that we've dealt with for 30 yrs is the local generac bigwig..they set me up the ATS and all the peripherals (customer bought just the generator)...i'll call the lead service tech there tomorrow...job happens to be about 500 yrds from the supply house:D
 
i have done two generac sets in the 11 kw size --- both times upon testing for the first time the generator transfer switch would not transfer back to the normal power source???? so we shutdown the generator set and of course it transfered from emergency to normal... we thought we had a problem??? ran the unit back through another test and it worked as designed from that point on??? is it in the program or what???

You need to manually transfer the switch a few times before putting it into operation...
 
Dip switch?

Dip switch?

Had an issue where the generator would start and shut off. There are dip switches in the generator for remote start, auto, etc.. In addition, make sure there is a utility power to the generator so it knows to shut off.

65%?

That is pretty extreme, any ATS I set up will swap over in the 90 to 95% range.
