(1) Screen (hydraulic tank) (2) Hose (3) Hydraulic pump (generator) (4) HoseNote: Do not start the generator with the engine above low idle speed. This can cause damage to the generator drive coupling group.The DC generator is an electro-mechanical device which is designed to convert the mechanical energy into DC electrical energy.The generator must be operated at the rated speed in order to develop the full rated voltage and power. For optimum performance, the speed must be maintained within a 50 RPM range.The generator is a compound field-wound unit which is self-regulated between zero and full load. The generated voltage is 230 volts at a constant speed of 1800 RPM.The generator is designed with extra thermal capacity in order to withstand electromagnet service with an adequate safety factor. The generator is mechanically mounted in order to resist shock and vibration from the machine.A hydraulic gear pump (3) takes suction from the hydraulic tank of the machine. The hydraulic oil passes through screen (1) through hose (2) to gear pump (3) . The hydraulic gear pump provides a constant flow of hydraulic oil to the generator circuit.Hydraulic oil from gear pump (3) passes through hose (4) to hydraulic motor (5) . The hydraulic oil is sent through a priority valve which is used to control the operation of the generator. When the priority valve is energized, hydraulic oil is allowed to flow to hydraulic motor (5) . When the priority valve is de-energized, the hydraulic oil is routed to the hydraulic tank. The hydraulic oil bypasses hydraulic motor (5) and passes through return hose (6) to hydraulic tank (7) .

(1) Grapple/magnet switch.When the grapple/magnet switch is turned to the magnet position, the priority valve is energized. The grapple/magnet switch is located on the right console. When the priority valve is energized, the spool piece in the valve shifts. When the valve shifts hydraulic oil is allowed to flow through the hydraulic manifold to hydraulic motor (5) . The hydraulic manifold regulates the hydraulic flow to hydraulic motor (5) . The regulation of the hydraulic oil maintains a constant motor speed. The hydraulic oil is used to operate hydraulic motor (5) . Hydraulic oil from hydraulic motor (5) returns to the hydraulic tank through hose (6) .Hydraulic motor (5) is used as the prime mover for the generator operation. The generator is coupled to the motor. The generator produces the required voltage and power for the magnet.The controller for the generator is equipped with a generator disconnect switch. The switch disconnects the entire electrical system of the generator control circuit. A shunt field circuit control is included in the controller for the generator. The field discharge circuit control is included in order to dissipate the magnets inductive energy when the
