Engine (Auto) Mode

When the electronic governor is switched to the Engine (Auto) mode, it is monitoring the rotation speed of the engine.
The hydraulic flow to the tub drive mechanism is regulated proportionally to the engine speed.  When the engine
begins to lug down, the hydraulic oil flow is reduced which in turn slows down the tub rotation.  With proper
calibration, the engine will only lug down to its optimum horsepower RPM and the tub rotation will be varied
proportionally to keep the engine at this RPM.  The result is a nearly constant load on the engine, which will maximize
grinding efficiency.  

See section3.11 (pg. 30) for calibration instructions.

Tub (Manual) Mode

In this mode the tub speed is constant and it will not change to match varying load conditions

IMPORTANT:

  Except when calibrating or trouble shooting the electronic governor always use the

Engine (Auto) mode of the electronic governor.

The Model RCB93 Electronic Governor regulates the speed
at which the tub rotates.  The electronic governor has two
modes of operation, the Engine (Auto) mode and the Tub
(Manual) mode. The Engine (Auto) mode is the preferred
mode of operation and should be used whenever possible.
