Abstract
A process for achieving engagement of a power source with a high inertia load by use of a clutch provides for the sequential engagement of the clutch until the speed of the power source drops to a first threshold, at which time the clutch is disengaged until the speed of the power source recovers to a second threshold. The process is repeated until the power source operates above the first threshold for a set period of time. The process may be terminated, leaving the clutch either engaged or disengaged, after a certain number of sequential attempts at engagement and disengagement have been made, or after a certain period of time has elapsed. The invention also relates to a system and associated process by which a microprocessor obtains various data regarding the operational state of a power source, load, and a clutch interposed therebetween. The data includes the speed of the power source and pressure, temperature and filter conditions of the associated clutch. The microprocessor also communicates with an ignition switch for the power source, a clutch engagement switch, and an equipment safety switch associated with the load. The system obtains the effective engagement of the load to the power source and the maintenance of that engagement while monitoring and recording operational data relevant to the effectiveness and efficiency of the system and the operational characteristics of the operator.
