The ECS supplies the data communications to:
•
The propulsion control system (PCS)
•
The alarm and monitoring system (AMS).
The standard version of the ECS includes the external communications that follow:
•
Two redundant CANBus lines to the PCS
•
Three redundant Modbus lines to the AMS.
For the schematic diagrams, refer to section
13.1 Schematic diagrams - general
.
NOTE:
The communications between the systems can be different. See the related
documentation from the approved propulsion control system manufacturer.
6.1.4.1
Propulsion control system
The propulsion control system (PCS) has the subsystems that follow:
•
Remote control system
The remote control system (RCS) has the primary functions that follow:
○
Start, stop and reverse
○
Automatic slow turning
Data about the ECS status is available in the RCS. This includes measured values of
sensors, defects and other indications (refer to the documentation of the remote control
manufacturer).
All commands to operate the engine (for example AHEAD or ASTERN) come from the RCS.
•
Engine safety system
The engine safety system (ESS) has the primary functions that follow:
○
Emergency stop
○
Overspeed protection
○
Automatic shutdown
○
Automatic slowdown
•
Telegraph system
The telegraph system transmits maneuvering signals from the bridge to the ECR and local
control panel.
NOTE:
The ESS and telegraph system operate independently and are also fully serviceable if
the RCS is defective.
6.1.4.2
Alarm and monitoring system
The alarm and monitoring system (AMS) is an external system and monitors the engine. The AMS
gives the operator alarms and status data of the engine to make sure of safe and satisfactory
engine operation.
The functions of the AMS are specified in the diesel engine control and optimizing specification
(DENIS). The AMS sends signals to the engine safety system to slow down or shut down the
engine.
For more data, see the documentation of the AMS manufacturer.
