ECM Sequence Of Operation (Normal Start-Stop)
Upon receipt of a signal to start, the ECM will check to assure that:a. An emergency stop signal is not present.b. All faults have been reset.c. All sensors are connected and operating properly.d. No abnormal engine control switch signals are present.e. The engine is not already running.f. The ECM microprocessor is functioning properly.g. The ECM is not in the programming mode.The ECM will not allow the start sequence to begin and will display the proper diagnostic code when applicable, if an above fault condition exists. However, once the ECM is satisfied that conditions are normal, it will energize the starting motor relay (SMR) and run relay (RR).If the generator set is a latching type when the starting motor magnetic switch (SMMS) is energized the latching fuel control solenoid (LFS) is also energized to turn the fuel on. This momentary current flow through a special latch mechanism on the solenoid holds the solenoid in the on position.If the generator set fuel system is an energized to run (ETR) type, the ECM will also signal for fuel (or the electronic governor) to be turned on by energizing the fuel control relay (FCR).If the cycle crank feature is enabled, the ECM will automatically crank-rest-crank the engine for adjustable time periods. If the generator set fails to start within the selected total crank time, the ECM will execute an overcrank fault. If a fault condition occurs while the engine is cranking, the ECM will terminate and lock out cranking. The ECM will display the applicable diagnostic code or light the appropriate LED.After the engine starts and has achieved the proper crank termination speed, the ECM will de-energize the starting motor by de-energizing SMR and will energize the crank termination relay (CTR). Once safe low idle oil pressure is achieved, the ECM will signal for the optional 2301 governor to accelerate the generator set to rated speed, by energizing the 2301 relay.The generator set will run as long as operating conditions remain normal and a signal to run is being received by the ECM. The ECM will display in sequence (each for a two second period) the engine lube oil pressure, water temperature, RPM, service hours, and system DC volts; by means of the digital display prior to or while the engine is operating. At the same time, the ECM will monitor for any fault or abnormal conditions that may occur.Upon loss of the run signal, the engine will continue to run for an adjustable cooldown period if the cooldown feature is utilized. However, if the cooldown feature is not used or if the ECM receives an off/reset signal, it will immediately de-energize the run relay. If the fuel system is an energize to shutdown (ETS) or latching type, the fuel circuit will be energized at this point. The fuel circuitry will be de-energized for energized to run (ETR) type (or 2301) systems. If the signal to run returns before the engine stops, the ECM will immediately go
