SEQUENCE OF OPERATION 8. 3. 1. GENERAL The MEC 2 Engine-generator controller is designed to start and stop an engine from either a local ("manual") or remote ("automatic") command. When this command is issued, the controller issues a run and crank output signal. The controller then monitors engine speed and when crank disconnect speed is reached, the crank signal is terminated. While the engine accelerates to normal speed, the controller continuously monitors the engines speed signal. Should the engine speed exceed the maximum predetermined setpoint, the over speed shutdown fault circuit will activate, terminating the run signal. In addition to over speed shutdown, the engine controller also monitors many other engine protection circuits and should they be activated, the engine will be stopped and/or alarm initiated. The engine will automatically stop for any shutdown condition, or when the remote and/or local start signal is removed. The engine controller operation includes time delay circuits for normal operating conditions such as start delays, cooldown and cranking periods. 8. 3. 2. MANUAL START/STOP SEQUENCE When the "RUN" pushbutton on the front faceplate keypad is pressed, an ENGINE START DELAY timer will be initiated.

TROUBLE SHOOTING A number of problems can cause the MEC 2 controller not to function properly. Consult the factory for any detailed information or for any problems not listed. CAUTION!!! Before opening the enclosure to perform any service task, it is imperative to isolate the control system from any possible source of power. Failure to do so may result in serious personal injury or death due to electrical shock. Service procedures must be undertaken by qualified personnel only! [. . . ]
