( REV. 08-04 )
3.8 Parts of the electronic governor
FUSE LIGHT
This light is on when the key switch is receiving power.
SENSOR LIGHT
This light is on whenever the electronic governor is receiving an adequate input signal from the sensor. For the sensor
light to work you must:
• Have the uid clutch engaged.
• The engine running at grinding RPM.
• The Mode Switch must be switched to the engine (auto) or manual position.
SPEED LIGHTS
These lights provide a relative indication of how fast your tub should be turning based on the output signal that the
electronic governor is sending to the electro-hydraulic valve.
MODE SWITCH
The mode switch has three possible positions.
The off position which turns the electronic governor off and two other positions which correspond to the tub (manual)
and engine (auto) modes of operation.
In the “tub (manual)” position the tub will rotate at a constant speed based on the settings of the Tub Limit Knob (Tub
Speed Knob).
The “engine (auto)” position uses all the functions of the Electronic Governor. The maximum tub speed will be limited
by the Tub Limit Knob (Tub Speed Knob), and the engine load will be controlled by the Engine Load Knob.
TUB LIMIT KNOB (TUB SPEED KNOB)
This knob sets the maximum speed at which the tub will rotate in both the tub (manual) and engine (auto) modes. In
the engine (auto) mode tub speed will vary between zero and this setting depending on the engine load.
