Schneider Electric XW6848+ Inverter Won't Qualify Generator Input

New install and everything works good.  I attempted to test AC generator and the inverter will not qualify it.  I let the generator run for almost a half hour and still not qualifying.  I checked the AC settings and they appear correct.  The Generator frequency stays at 62 HZ and the voltage on AC2 is 236.6.  AC2 L2 voltage is at 118.9 and AC2 L1 voltage is at 118.2 which seems normal.  The frequency setting to qualify is
from 54.5 - 65 Hz.

Any info appreciated perhaps I may be missing something.  I notice the  AC2 Transfer delay is set at "36"....I assume that number is in seconds.  I am attaching screen shots of the settings and actual run data from the inverter.

One more question....does the Grid input have to be disconnected before the generator can be online?  Perhaps that is necessary to work.  Maybe Grid and Generator power can't be on at the same time.  Guess what.....that was the problem....I forgot to disconnect the grid input for the test....... :#:blush:
Thanks in advance.

    So it worked after you disconnected from the grid ?

    I was gonna say...grid input has to be off...glad you worked it out...good info for others

    Sorry a little late....Yes, it works perfectly fine....

    I just had a thought...I know I said grid power has to be off...and I know that worked...I'm just curious now

    you might could try AC priority....if you set it to 2 generator input, does it still do the same thing
