Digital Control Unit (DCU 210E) (1) - The DCU is the main user interface. The DCU displays engine and generator data, such as oil pressure and coolant temperature, on the main screen. The DCU also shows alarms in the alarm list and can be configured from the menu. For information on navigation of the DCU 210E, refer to System Operations, M0070550, "Display Screens".Stop Button (2) - Stops the engine. Depending on the configuration, the button may have to be held down until the engine fully stops.Start Button (3) - Starts the engine.

If the Alarm list is already on the screen and the buzzer is active, this button will silence the buzzer instead.Throttle (6) - Controls engine speed. When the ECS is set to "Local" mode, this throttle is enabled. The genset engine will go to rated speed, then it can be adjusted by this throttle. The propulsion engine will remain at the current speed until the local throttle is turned to within 50 rpm of the current speed, then the engine will follow the local throttle. For the MGCP, press the left arrow to decrease engine speed and the right arrow to increase engine speed. For the MECP II, rotate the knob counterclockwise to decrease the engine speed. Rotate the knob clockwise to increase engine speed.Emergency Stop Button (E-Stop) (7) - This button immediately stops the engine and removes power from the ECM.Engine Control Switch (ECS) (8) - The engine control switch (ECS) has three positions. The "OFF" position is on the left. This position turns off the key switch to the DCU and ECM. The "Local" position is located in the middle. In this position, only the local control panel can start or stop the engine. The local throttle is enabled. The "Remote" position is on the right. This position disables local starting or stopping of the engine. Remote control is enabled. Local E-Stop and crank override still work in this position.
