TRACE SW4024 shows Generator under/over speed error
The Trace SW4024 120/60hz has a preset AC2 allowable frequency range from (53-67 hz)
If there is a frequency out of that range you will get a generator under/over frequency.
Solution: Service generator, replace bushings if applicable, and try to reduce max charge rate to see if the remedies the generator input.
