In AUTO mode, you can select these functions:

• Island

• Engine drive
• Automatic mains failure (AMF)
• Site battery monitoring
• Cyclic
• Remote start/stop
• Auto exercise
To go to AUTO mode, push the Mode selection button until AUTO mode is shown on the display.
4.2.1 Island
The controller operates in island when:
• Mains monitoring and site battery monitoring are not enabled.
• Cyclic and auto exercise are not enabled.
In the smart connect software, go to Mains > Configuration > Mains monitoring and make sure that mains
monitoring is not enabled. To make sure that auto exercise is not enabled for events 1 and 2, go to Module > Auto
Exercise > Event 1/Event 2.
The controller automatically starts the genset and closes the generator breaker at a digital start command. When the stop
command is given, the generator breaker opens, and the genset is stopped after a cooling down period.
Use a digital input to activate and deactive the start and stop commands. You cannot use the display buttons in AUTO
mode.
