The error is because the generator has no neutral-ground bond like the main utility breaker panel.
You can use bypass or make a bonding plug. To make a bonding plug... get a replacement plug from the hardware store. Get a 100,000 ohm 1/2 watt or 1 watt resistor from the electronics supply house. Connect the neutral and ground pins within the plug. No cord gets attached. Insert the plug into one of the generator outlets and the error will clear.
I tried using a 100,000 ohm 1/2 watt resistor and it works fine (no E2, open ground, error) as long as the a/c compressor doesn't turn on. When the a/c compressor turns on, the Progessive Industries EMS shuts off power to the toy hauler and throws back the E2, open ground, error. So, removed the resistor and patched a solid wire from ground to neutral. No more E2 errors when the a/c compressor kicks on.
Thanks to everybody for your help!
