8. GENSET controller
8.1 GENSET controller overview
8.1.1 Description
A GENSET controller controls and protects a diesel engine and generator (that is, a genset), as well as the generator breaker. A
system can include a number of GENSET controllers.
The GENSET controllers work together to ensure effective power management. This includes load-dependent start and stop, and
may include setting the genset priority order, managing heavy consumers, and, if necessary, tripping non-essential loads.
8.1.2 Applications
The system must have at least one GENSET controller.
Each GENSET controller can control up to four heavy consumers (HC) and connect up to three non-essential load groups (NEL).
