There’s no way to bypass a single error condition. The unit is either plugged in-line, or it isn’t.
The display on the unit continuously scrolls, at 2 second intervals, all AC power information: voltage(s), current(s), frequency, error code, previous error code (if applicable).
What frequency was it displaying?
If AC power frequency deviates plus/minus 9 Hz from 60 Hz, the EMS will shut down AC power. An Error code of E 7 will be displayed when the frequency is high; and an Error code of E 8 will be displayed when frequency is low.
What error code was it displaying?
I would have checked the frequency with a DVOM, and confirmed that either the park power was out of spec, or the EMS was faulty.
