4. Modes of operation
4.1 Operation mode
The controller has two running modes:
• AUTO: The controller operates automatically, and the operator cannot initiate sequences manually.
• Manual: The operator has to initiate all sequences. You can do this with the buttons, Modbus commands, or digital
inputs.
4.2 AUTO mode
In AUTO mode, you can select these functions:
• Island
• Engine drive
• Automatic Mains Failure
• Remote start/stop
• Auto exercise
If the controller is not in AUTO mode, push the mode selection button to change the running mode to AUTO.
4.2.1
Island
The controller operates in island when:
• Mains monitoring is not enabled.
• Auto exercise is 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.
