Sequences
The following contains information about the sequences of the engine, the generator breaker
and, the mains breaker. These sequences are automatically initiated if the auto mode is
selected, or if the commands are selected in the semi-auto mode.
In the semi-auto mode the selected sequence is the only sequence initiated (e.g. press the
START push-button: The engine will start, but no subsequent synchronizing is initiated).
The following sequences will be illustrated below:
•
START sequence
•
STOP sequence
•
Breaker sequences
