9. EMERGENCY genset controller
9.1 EMERGENCY genset controller overview
9.1.1 Description
An EMERGENCY genset controller controls and protects an emergency genset (both the engine and the generator), as well as the
generator breaker, and the emergency busbar tie breaker. By default, the EMERGENCY genset controller automatically starts the
emergency generator when there is no voltage on the busbar.
The EMERGENCY genset controller includes a test function, to make regular testing of the emergency generator easier.
The EMERGENCY genset controller allows harbour operation, so that the genset can be used as the ship generator when in
harbour. Apart from this, the emergency genset does not normally supply power to the system.
9.1.2 Applications
The system can have 0 or 1 EMERGENCY genset controllers. Each EMERGENCY genset controller can connect up to three non-
essential load groups (NEL).
