Analogue load sharing is automatically not active when:
• The genset breaker is open.
Analogue load sharing is automatically ignored when the power management system gives the genset controller a power set point:
• You can use M-Logic to force the controller to use analogue load sharing. This allows analogue load sharing with externally
controlled gensets. See Load sharing type for more information.
• You can also use M-Logic to activate analogue load sharing if the power management CAN bus communication fails.

See Genset functions, Load sharing in Option G5 Power management for more information.
How does it work
A voltage signal proportional to the load produced by the genset is supplied on the load sharing line. When the generator load is 0
%, 0 V DC is supplied. When the load is 100 %, the voltage is 4 V DC, as shown below. Active load sharing is shown. Reactive load
sharing is similar.

6.4.2 Working principle
The controller supplies a voltage on the load sharing line proportional to the genset's actual load. This voltage comes from an
internal power transducer. At the same time, the actual voltage on the load sharing line is measured.
