Sequences
The following contains information about the sequences of the engine, the generator breaker
and, if installed, 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 synchronising is initiated).
The following sequences will be illustrated below:
• START sequence
• STOP sequence
• Breaker sequences
If island operation is selected, the digital input ‘MB closed’ must NOT be activated with a 12/24 volt
input signal. A ‘mains breaker failure’ will occur, if the wiring of the mains breaker feedback inputs
is wrong.

The drawings illustrate the start sequences of the gen-set.
