Speed Setting Menu
Speed adjustments are the settings that affect the speed reference.
1. START SPEED (RPM) is the initial speed reference for the speed control
prior to starting. Start Speed must be set above cranking speed and below
the speed achieved with the start fuel limit setting (light-off speed). A ramp
from the Start Speed to idle or rated, whichever is selected and permissive,
begins when the engine accelerates to Start Speed. The ramp time is the
accel ramp time setting or the decel ramp time setting as determined by the
idle/rated selection and permissives.
2. RAISE SPEED LIMIT (RPM) is the maximum speed reference setting. It is
used to limit the Raise Speed and Remote Speed Setting inputs to a
maximum. It normally is set at the speed at which the engine operates at full
load.
3. LOWER SPEED LIMIT (RPM) is the minimum speed reference setting. It is
used to limit the Lower Speed and Remote Speed Setting inputs to a
minimum. It normally is set at the minimum operating speed of the engine.
