LAMP GP-WARNING 9X8079 - Caterpillar

Dual Dynamic Operation of Engine (Marine Propulsion)
The ADEM governor is set up to provide a variable speed control (default). The ADEM governor is also set up to provide a constant speed control (selected through input to ADEM control). The variable speed control is the default configuration that is used to propel the vessel.A second group of governor gains are used with the constant speed control. The second group of governor gains are selected by the dual dynamic select switch. Constant speed control is desired when an electric propulsion system is used with dynamic positioning.To use constant speed control, set the following parameters for this feature to work properly:
Determine a known constant speed for the application. The constant speed value is then programmed in the ADEM. This value is entered with the Electronic Technician (ET) for the parameter "Engine Governor Desired Constant Speed". The default value is set at the rated speed.
Tune the ADEM control for proper operation. The following governor gain parameters are used to tune the engine for proper operation: "Governor Gain Factor #2", "Governor Minimum Stability Factor #2" and "Governor Maximum Stability Factor #2".Caterpillar recommends a validation of the preset parameters during commissioning procedure. The parameters that have been set at the factory may need adjusting.Global Throttle Select and Global Throttle PWM Input Features (Marine Propulsion)
The global throttle is available with dual dynamics in order to allow a third throttle input. This feature allows the user to change the throttle input from variable speed control to a load share module. This feature also allows the user to synchronizer the module when constant speed is desired. The global throttle input is selected by grounding the "Global Throttle Select" input to the ADEM control.For more information on engine speed governing, refer to System Systems Operation/Testing And Adjusting and Adjusting, RENR5083, "C280 Marine Engines".
