Excessive load power (ID1)AC output short circuit (ID2)Off-grid output overvoltage or grid/generator overvoltage (ID3)Load too high, grid undervoltage, or Gateway air switch not closed (ID4)Inductive load overload or grid overfrequency (ID5)Capacitive load overload or grid underfrequency (ID6)
What to check
STEP 1
ID1: Reduce load power. ID2: Check for AC output short circuit. ID3: Reduce generating load or check grid/generator voltage. ID4: Reduce load, confirm Gateway air switch closed, check grid/engine voltage. ID5: Reduce inductive load, check Gateway switch. ID6: Reduce capacitive load, check Gateway switch
STEP 2
Check grid or generator voltage/frequency as appropriate to the sub-fault
