Marine Commercial Control
System (MCC)
Marine Commercial Control (MCC), is a type-approved
control system that monitors your Volvo Penta engine.
MCC comprises an marine control unit (MCU), remote
panel (RP), shutdown unit (SDU) and a relay card.
The MCU is the main system panel and it
communicates with all of the engine control units. The
slave panel may be located outside the engine
compartment and handles in exactly the same way as
the MCU.
The SDU manages automatic engine shutdown should
the engine show critically low oil pressure (including
reverse gear) or high coolant temperature. It also has
overspeed protection. Electronic systems in the vicinity
of the engine comprise the engine management
system (EMS) and a power management unit (PM).
The engine management unit manages the injection of
fuel with the aid of a number of sensors. The power
management system manages primary and secondary
battery supply and supplies electrical power to the
engine management unit, MCU and SDU. The unit has
overcurrent protection with automatic reset.
