Hi Don, I too have been having a difficulty with the Trace exercise mode.  This is on a dual 4024 with a Kohler 11kw generator.  I have all the same settings as you except for a different exercise time. Everytime I check the clock on the generator it has not advanced at all.  The customer even taped a small candle to the outside of the weathertight enclosure where the exhaust exits to see if it would melt in case the timer was not functioning properly.  We had no candle melt downs.  It never occured to me that the Trace 4024, according to what Dave Palumbo has found out, is not able to run the exercise mode. Now here is one of the real values of this  group of wrenches being able to help and support eachother in trying to install safe and reliable systems.  Anyone else have any ideals on this situation?

Greetings wrenchers!
 
I could use a little help with a SW4024.  I gave Trace engineering a week, and they have yet to respond.  Should I be surprised? 
 
    The inverter will not exercise the generator. The generator can be started from the inverter manually. I am on "RY7: COM/NO" . Time of day is set. Quiet time is set for "00:00/06:00". Exercise period is set for 7 days. RY7 function is set to "run". Generator is set to "auto". The generator is a Kohler 8.5 RMY, two-wire start. I checked on the job 3 weeks after these settings were implemented, and the generator clock tells me it hasn't run. There are no error lights lit.
 
    Since asking for help from Trace, I noticed that 00:00 is a stupid number.  Last trip to the job, I changed the quiet time settings to 23:00/06:00.  It hasn't quite been a week since I changed the settings.  Does anyone think that I may have fixed the problem? And does anyone know when I can expect the inverter to exercise the generator?  How does that timer work?  I'll be going back up to the job next week to look at the time clock on the generator.  Hopefully it'll show another tenth of an hour.  If not, the lady won't pay me, and man, I could sure use the money.  Or what else? Thanks.
