secondary base speed is 1,800 rpm. The Accelerator Position setting C is expressed as a percentage and
tells the Volvo Penta ECU where to set the engine speed (trim) relative to the base speed. The range of
the setting is the base speed
120 rpm. A setting of 0% will cause the engine to run at 120 rpm below the
base speed, a setting of 50% will cause the engine to run at the base speed, and a setting of 100% will
cause the engine to run at 120 rpm above the base speed. The Accelerator Position setting is linear with
a gain of 2.4 rpm/percentage. This setting is not saved in nonvolatile memory and defaults back to 50%
after DGC-2020 operating power is cycled.
If the engine is configured as MTU MDEC, the configuration of the following settings is necessary:
 MDEC Module Type D
 Speed Demand Switch E
 Engine RPM F
If the engine is configured as MTU ADEC, the configuration of the following settings is necessary:
 Speed Demand Switch E - Specifies speed demand source for the MTU engine ECU.
 Engine RPM F - Requested engine RPM when speed demand source is analog CAN for an MTU ECU.
 Overspeed Test G - Temporarily drives an MTU ECU into overspeed for testing overspeed.
 Governor Param Switch Over H - Specifies which governor parameters an MTU ECU should use.
 Trip Reset I - Resets trip information such as trip fuel used, trip hours, trip idle time, etc.
 Int Oil Prime J - Causes an MTU ECU engine to perform an internal lubrication cycle.
If the engine is configured as MTU ECU7, the configuration of the following settings is necessary:
 Speed Demand Switch E - Specifies speed demand source for the MTU engine ECU.
 Engine RPM F - Requested engine RPM when speed demand source is analog CAN for an MTU ECU.
 Overspeed Test G - Temporarily drives an MTU ECU into overspeed for testing overspeed.
 Speed Up K - Increases speed of the MTU ECU.
 Speed Down L - Decreases speed of the MTU ECU.
 Speed Demand Limit M - Turns the speed demand limit on or off.
 Increased Idle N - Sets the MTU ECU idle.
 Trip Reset I - Resets trip information such as trip fuel used, trip hours, trip idle time, etc.
 Int Oil Prime J - Causes an MTU ECU engine to perform an internal lubrication cycle.
 Engine Start Prime O - Turns the engine start prime on or off.
 Fan Override P - Turns the fan override on or off.
 Mode Switch Q - Turns the mode switch on or off.
 Governor Param Switch Over H - Specifies which governor parameters an MTU ECU should use.
 Governor Param Set Select R - Sets the governor parameter set select.
 CAN Rating Switch 1 & 2 S - Turns the CAN rating switch 1 & 2 on or off.
 Cylinder Cutout Disable 1 & 2 T - Turns the cylinder cutout disable 1 & 2 on or off.
The Volvo Penta ECU configuration is applicable only to the EDC3 and EMS2 models of Volvo Penta
engine controllers.
