AXLE 8K5997 - Caterpillar

This control panel (part number 4W8000) is being produced in conjunction with the new engine wiring harness program. Along with the wiring harness, a junction box has been mounted on the engine to accommodate the junction of the engine and generator/control panel wiring.The panel (4W8000) differs from the previous 3N8900 panel (Type 1 through Type 5) in physical arrangement of components as well as electrical logic. The new panel provides the capability of changing from a manual start/stop panel to an automatic start/stop panel by simply switching modules and reconnecting some wiring at the control panel terminal strip. Also, the panel can now be equipped with the 2301 speed sensing governor which is mounted in the panel. It can be used on energize to run or shutoff engine wiring systems.The uses of the generator mounted control panel are: To help control the electric power made by the generator set.To monitor (check) the operation of the generator set.To help protect the generator set engine from damage caused by low oil pressure, high coolant temperature, overspeed and overcrank.To help with the transfer of electrical load to and from the generator set.To help parallel two or more units onto the same bus.Schematic Layout
