RT-flex Training Function of the RT-flexControl System WECS-9520 Control Systems Overview The RT-flex engine control consists of internal engine control WECS-9520 and the external Propulsion Control System (PCS) (not W?rtsil? supply) with Remote Control (ECR, Bridge) Safety System Electric Governor Alarm Monitoring System Control Systems Overview RT-flex Concept WECS-9520 Engine control system WECS-9520 The WECS-9520 is the core engine control, it processes all actuation, regulation and control directly linked to the engine: Common rail monitoring and pressure regulation Injection and exhaust- and start valve control and monitoring Interfacing external systems via CANopen or MOD Bus Engine performance tuning, IMO setting and -monitoring WECS-9520 has no central computer but each cylinder has its own FCM-20 module for the cylinder related- and common functions. WECS-9520 These FCM-20 modules are mounted directly on the engine and communicate via internal System CAN Bus. An operator access to the WECS-9520 is integrated in the user interface for the propulsion control system and flexView. WECS-9520 is neither an engine remote control system nor a safety system. Remote Control Remote control system: Kongsberg Maritime, NABTESCO, Lyngs? The remote control is the operator interface to the engine. Selectable control panels deliver following manoeuvring commands to the WECS-9520 via CANbus or MODbus connection: Start, Brake air ? Air run Stop ? Slow turning Ahead ? Slow turning failure reset Astern The remote control processes the engine telegraph command with internal settings (scaling, load program etc.) to a speed reference signal for the governing system. Lyngs? Kongsberg Maritime NABTESCO Electronic Governor Electronic governor system: Kongsberg Maritime, NABTESCO, Lyngs? The electronic governor system supplies the fuel command for the WECS-9520 and regulates the engine speed. The fuel command is calculated from the speed reference
