SHIM 0930122 - Caterpillar

The tables that follow list the following information: Sequence of events, Action that is taken by the Operator of the PTO and Position of the controlling equipment. The positions produce the resultant engine RPM within a specific programmed limit. The following components are used in order to provide a demonstration of the interaction of different systems: Cruise Control On/Off switch, PTO On/Off switch, Set/Resume switch, Fast Idle On/Off switch and Accelerator Pedal. Most systems will require only some of the components.Note: Before performing each test, reset the parameters to the factory defaults. This will ensure that a parameter that was used for one test is not active for another test. The parameters that are given in the tables must be programmed in order to perform the tests.The Three Programmable Engine Limits
