Sulzer RTA Local Control Station

 

 

 

This page describes the local control station on a Sulzer RTA96C 12 cylinder engine as fitted to the latest generation of container ships.

 

The local control station is situated halfway along the engine on the fuel pump level where the engine governor and air start distributor are also situated.

Although the engine is normally operated from the bridge, in an emergency the control can be simply changed over to local control from the engine side.

 

   

As well as the local control levers shown above there is a tacho, a telegraph, aux.blower start buttons and local speed controls

A gauge panel gives an overview of important parameters.

The instructions at the local control panel are reproduced below.

MANOEUVRING INSTRUCTIONS

A)

LOCAL CONTROL

(RUNNING WITH GOVERNOR)

 

STARTING

 

      PRESELECT ALL AUXILIARY BLOWERS

      MOVE MANOEUVRING LEVER TO RUN AHEAD OR RUN ASTERN

      SET LOCAL CONTROL SPEED SETTING TO ABOUT 40% OF NOMINAL SPEED (RPM)

      MOVE MANOEUVRING LEVER TO START UNTIL ENGINE RUNS

      SLOWLY INCREASE LOCAL CONTROL SPEED SETTING TO REQUIRED SPEED

 

STOPPING

 

      REDUCE LOCAL CONTROL SPEED SETTING

      MOVE STOP LEVER TO STOP POSITION

      FOR AUXILIARY BLOWERS CUT OFF MOVE THE REVERSING LEVER TO RC POSITION

 

TAKE OVER TO LOCAL CONTROL

 

      ADJUST THE LOCAL CONTROL SPEED SETTING TO THE SAME LEVEL AS INDICATED BY TACHOMETER

 

      MOVE THE MANOEUVRING LEVER TO RUN AHEAD OR RUN ASTERN (THE SAME ROTATIONAL DIRECTION IN WHICH THE ENGINE IS RUNNING)

 

 

CHANGE OVER TO REMOTE CONTROL

 

      MOVE THE MANOEUVRING LEVER TO REMOTE CONTROL POSITION AND PRESS REMOTE CONTROL PUSH BUTTON ON LOCAL CONTROL PANEL

EMERGENCY CONTROL

(RUNNING WITH FUEL CONTROL LEVER)

 

STARTING

 

      PRESELECT ALL AUXILIARY BLOWERS

      MOVE MANOEUVRING LEVER TO RUN AHEAD OR RUN ASTERN

      MOVE FUEL CONTROL LEVER TO ABOUT POSITION 34

      MOVE MANOEUVRING LEVER TO START UNTIL ENGINE RUNS

      SLOWLY INCREASE FUEL CONTROL LEVER UNTIL ENGINE RUNS AT REQUIRED SPEED

 

STOPPING

 

      MOVE FUEL CONTROL LEVER TO ZERO

      MOVE STOP LEVER TO STOP POSITION

      FOR AUXILIARY BLOWERS CUT OFF MOVE THE REVERSING LEVER TO RC POSITION

 

TAKE OVER TO LOCAL CONTROL

 

      QUICKLY BRING THE FUEL CONTROL LEVER INTO THE SAME POSITION AS THE FUEL LINKAGE AND LINK THEM TOGETHER

      CHECK THE ENGINE SPEED

 

                                                  

EMERGENCY CONTROL

(RUNNING WITH FUEL CONTROL PUSH BUTTONS)

 

      INSTEAD OF RUNNING THE ENGINE WITH THE FUEL CONTROL LEVER IT IS POSSIBLE TO ADJUST THE ENGINE POWER WITH THE PUSH BUTTONS ON THE LOCAL CONTROL PANEL

 

 

There are three levers on the local control station; A MANOEUVRING lever which is normally in the REMOTE CONTROL position, a RUN-STOP lever which is normally in the RUN position and a FUEL CONTROL lever which is normally in the REMOTE CONTROL position.

The MANOEUVRING lever and the RUN-STOP lever are connected by rods which control the starting pneumatic control valves - see The Sulzer RTA Air Start System.

 

The local control can operate under two different conditions; with or without the governor. If the governor is operational then all that needs to be done to change over whilst running is to match the speed setting control on the control panel with the speed of the engine and then move the MANOEUVRING lever into the appropriate run position (ahead or astern).

If changing over to local control because the governor is faulty, then the FUEL CONTROL lever must be connected to the fuel linkage.

This is achieved by moving the FUEL CONTROL lever out of its remote control position and locating the spring loaded pin in the hole in the fuel control linkage  shown on in the photo above. The fuel is controlled by winding the handwheel on the FUEL CONTROL lever  which moves the control rod to the fuel pump shaft
