The bus power supply enables the bus system to be powered directly by the individual
controllers (no central bus power supply). The type of bus power supply can be
selected.
· Off: No bus power supply via the controller.
· Automatically: The bus power supply (LPB) via the controller is automatically
switched on and off depending on the requirements of the LPB.
The display shows whether the controller currently supplies power to the bus:
· Off: The bus power supply via controller is currently inactive.
· On: The bus power supply via controller is currently active. At the moment, the
controller supplies some of the power required by the bus.
