WIRING GP-ELECTRONIC CONTROL 3540045 - Caterpillar

Read this entire manual and all other publications pertaining to the work to be performed before installing, operating, or servicing this equipment. Practice all plant and safety instructions and precautions. Failure to follow instructions can cause personal injury and/or property damage.The engine, turbine, or other type of prime mover should be equipped with an overspeed (overtemperature, or overpressure, where applicable) shutdown device(s), that operates totally independently of the prime mover control device(s) to protect against runaway or damage to the engine, turbine, or other type of prime mover with possible personal injury or loss of life should the mechanical-hydraulic governor(s) or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), the linkage(s), or the controlled device(s) fail.
Auxiliary Equipment
Automatic Safety Shutdown And Alarms (Manual 36652)
A "Lube Oil Pressure Failure Shutdown and Alarm Device" (figure 1-2 or 1-3) protects the engine in the event of the loss of normal lube oil operating pressure. It monitors lubricating-oil pressure and is so designed that the shutdown pressure level becomes progressively higher as engine speed increases.A second device, a "Lube Oil Pressure Failure With Excessive Vacuum Shutdown and Alarm", has the added feature of monitoring the inlet side of the engine oil pump. Excessive vacuum will trigger the shutdown and alarm system.A time-delay feature (see figure 1-2) allows the engine to be started without lubricating-oil pressure yet prevents prolonged operation if a safe pressure level is not reached within the preset time.A "Cooling Water Pressure Failure Shutdown" device (figure 1-3) protects the engine from a drop in the normal operating pressure of the water cooling system. A time-delay and bypass feature is common to the system when the oil and water shutdown devices are used together.Load Control Override (Manual 36695)
This mechanism overrides the normal functioning of the load-control system reducing generator field excitation current during engine startup, wheel slip, or transition.Manifold Air Pressure Bias Fuel Limiter (Manual 36601 and 36695)
The fuel limiter acts to restrict engine fuel during acceleration as a function of manifold air pressure to ensure more complete combustion, reducing smoke to a minimum and improving acceleration. Two models of this device are available, a two-barrel model (manual 36601) or a single-barrel (inline) model (manual 36695). While physically dissimilar in appearance and installation, they are essentially identical in function and achieve the same end result. Parts information for the oil filter used in conjunction with either model fuel limiter is found in figure 7-16).Two variations of bias linkages are available for use in conjunction with either model fuel limiter as described above and are covered in detail in the applicable fuel limiter manual.Overspeed Valve
This is a backup safety mechanism used in conjunction with a separate overspeed-shutdown trip. It monitors the tripping oil-supply pressure and causes engine shutdown in the event the tripping oil pressure drops below a safe level. See figure 3-1 for a schematic representation of the valve.Introduction
