6.2.5.1 Propulsion control system
The propulsion control system (PCS) has the subsystems that follow:
•
The remote control system (RCS)
•
The electronic speed control system (SCS)
•
The safety system
•
The telegraph system (ECS).
NOTE: The safety system and telegraph system operate independently and are fully
serviceable if the RCS becomes defective.
6.2.5.2 Remote control system
The remote control system (RCS) has the primary functions that follow:
•
Start, stop and reverse
•
Automatic slow turning
•
Auxiliary blower control
•
Transfer control
•
Automatic speed setting program.
Data about the WECS-9520 status is available in the RCS. This includes measured values of
sensors, defects and other indications (see the documentation of the remote control
manufacturer).
The operator can adjust the user parameters, eg maximum fuel limit, running-in mode and fuel
quality setting (FQS).
The operator selects the necessary command on the RCS (eg AHEAD or ASTERN). The RCS
sends the commands to operate the engine.
If there is a malfunction, the WECS-9520 sends an alarm signal to the AMS, or a slow-down/
shut-down signal to the safety system.
The parameters are divided into two groups:
•
User parameters, access without password
•
Expert parameters, access with password only.
The operator can adjust the user parameters, eg maximum fuel limit, running-in mode and fuel
quality setting (FQS).
Expert parameters are changed only by service personnel, usually during commissioning. A
typical expert parameter is the firing order of the engine, which is set only once.
6.2.5.3 Electronic speed control system
The speed control system is part of the PCS.
The electronic speed control system has the functions that follow:
•
Keeps the engine speed at the necessary value (from remote control)
