“Over load” LED flashes when total current exceeds the rated one.
Load Protection activated 60 seconds after the current is 1.2 times more than rate one.
Load Protection activated at once when the current 1.5 times more than rate one.
When protection activated, all the loads will be disconnected, then “Over load” LED stops
flashing but keeps on.
After the malfunction removed, press any button to return to work.
