SPEED DROOP KNOB - Controls the speed change from no load to full load.SYNCHRONIZER KNOB - Throttle. Controls engine speed.LOAD LIMIT KNOB - Controls the horsepower output of the engine to the nameplate rating.SYNCHRONIZER INDICATOR - Indicates how many turns of the synchronizer knob have been made.LOAD INDICATOR POINTER - Indicates relative load.Starting
Make all preliminary starting checks.1. Turn the load limit knob until the indicator is between "5" and "7".2. Turn the synchronizer knob clockwise until the indicator is at "8".3. Start the engine and run it at 900 RPM for 5 minutes. To adjust speed turn the synchronizer knob.4. Turn the load limit knob to "10" to carry the load.5. Turn the synchronizer knob clockwise until the engine runs at full governed speed.6. Speed droop is dictated by the application. A. Single unit operation. When constant speed or frequency is required, set the speed droop knob to "O".B. Parallel operation. When several units are operated in parallel and constant speed or frequency is required, the first unit on the line may be set at "O" droop and additional units set from "30" to "70". If constant speed is not required, set the speed droop from "30" to "70" on all units.7. Apply the load and readjust the synchronizer knob to obtain the desired division. The load indicator pointer behind the load limit knob indicates the relative load.When engines are paralleled, individual engine output is controlled by the synchronizer knob. Turn the knob clockwise to assume more of the load.Stopping The Engine
1. Remove the load and move the synchronizer knob counterclockwise to reduce the speed to 900 RPM. Allow the engine to cool for 5 minutes.2. Stop the engine by turning the load limit knob to "O".
