31 If there are no shutdown events that are active or present, and after any pre-crank or start-aid activities have completed, the starter motor and fuel control will be activated. The EMCP 3 GSC will activate Relay Output #1 to activate the starter motor magnetic switch, and Relay Output #2 to activate the fuel enable circuit. On electronic engines with ADEM™ A3 or newer engine ECM, the start command and fuel enable signals will be sent from the EMCP 3 GSC to the engine ECM via the J1939 data link. After receiving the signals, the engine ECM will operate the fuel control relay and starter motor magnetic switch. Relay outputs #1 and #2 will not be used on those engines. Relay Output #1 will remain active until the programmed ENGINE CRANK TIME has been reached, or until the engine speed has reached the programmed CRANK TERMINATE SPEED setpoint value. NOTE: the EMCP 3 GSC Crank setpoints: number of cranks, crank duration, and crank terminate speed are not used on engines using the ADEM™ A4 with the Common Engine Interface option or newer engine ECM. These values must be adjusted in the engine ECM. CAUTION: To determine the exact starting sequence for your engine, consult your engine’s Operation and Maintenance Manual. STOPPING THE ENGINE Once the engine is started, the engine can be stopped by pressing the STOP KEY on the control panel. If the control is in AUTO, the engine can also be stopped by DEACTIVATING all of the remote initiate commands. There are three possible sources for this command: 1. The remote initiate input (digital input #2) 2. The remote initial command over the Modbus datalink (register number 1055) 3. The Programmable Cycle Timer Once the STOP command is issued, the control will go into COOLDOWN MODE. Cooldown mode will run for the duration of time that it is programmed in the COOLDOWN DURATION setpoint. If the cooldown time is set for zero minutes, the engine will stop immediately. On engines with ADEM™ A4 or newer engine ECM, the cooldown timer in the EMCP 3 GSC should be set to 0 (Zero) minutes because the cooldown time is controlled from the engine ECM (if this is not done, both cooldown timers will run in sequence). Also, the ENGINE OPERATING STATE INPUT CONFIGURATION parameter must be set to CAN INPUT. for 5 The cooldown timer can be overridden by pressing and holding the STOP KEY seconds. The display will show a splash screen that will ask if you want to BYPASS COOLDOWN? or continue with the cooldown cycle. If the ENTER KEY bypassed.

If the ESCAPE KEY is pressed from the splash screen, the cooldown cycle will continue until the programmed cooldown time has elapsed.
