Engine control system
The engine control system (ECS) is an embedded system that has a modular design. Some
parts and functions in the ECS system configuration are optional and are related to the
application.
The name of the WinGD engine control system is UNIfied Controls Flex (UNIC-flex). It has the
items that follow:
•
Main control module (MCM-11)
The main control module (MCM-11) is installed at the local maneuvering stand in the
terminal box E25. The MCM-11 has functions for speed control, engine control and
common engine functions (eg starting air shut-off valve). External control systems
transmit data to the MCM-11.
•
Local display unit (LDU-20)
One local display unit (LDU-20) is installed at the local maneuvering stand at the free
end. The other LDU-20 is installed in the engine control room (ECR). External control
systems transmit data to the LDU-20. The LDU-20 gives the operator a graphical user
interface for access to data and system adjustments.
•
Input/output module (IOM-10)
The input/output module (IOM-10) is installed at the rail unit in the terminal box E90. The
IOM-10 has the engine control functions (eg exhaust waste gate control) and redundant
sensor and actuator signals of the MCM-11.
•
Cylinder control module (CCM-20)
The cylinder control modules (CCM-20) for each cylinder are installed on the rail unit in
the terminal box E95. The CCM-20 have different cylinder-related and engine-related
control functions. The CCM-20 also have redundant global functions for the engine
control.
Redundant CAN system buses connect all these modules.
Two 230 VAC supplies from the ship installation, supply electrical power to E85.1 to E85.n. The
two 230 VAC supplies are isolated from each other.
The power supplies have redundancy. If it is necessary to isolate the ECS, make sure that each
of the two 230 VAC power supplies are set to off. This will prevent injury to personnel.
Each control function that is important for engine operation has redundancy in the ECS.
