3.3.1 Operation Mode AUTO
In operation mode AUTO breakers and genset are under easYgen
control. Start and stop of the engine is managed automatically
together with open, close, and breaker transition.
Depending on settings and application status, AUTO control can:
n
supply load by mains
n
supply load by generator
n
transition load supply from mains to generator or from gener‐
ator to mains
n
start the engine
n
stop the engine
Situation
n
Mains becomes abnormal because one or more of the parame‐
ters below misses its well defined working range:
–
“Overvoltage”
–
“Undervoltage”
–
“Overfrequency”
–
“Underfrequency”
–
“Mains voltage asymmetry”
–
“Mains phase rotation fail”
Start procedure will include breaker handling, engine start, and sig‐
naling/warning.
All of the above listed parameters are (back) in normal range.
Stop procedure will include breaker handling, engine stand-by, and
signaling/warning.
3.3.2 Operation Mode MANual

pendently from each other under easYgen control.
