DCA-150SSJU3 — ENGINE OPERATING PANEL

9.Pre-Heat Lamp – When lit, indicates engine is in the pre-heating mode (for starting during cold weather operating conditiions). When lamp goes off engine is ready for starting.

10.Warning Lamp –This lamp will illuminate when a critical engine fault has occured.

11.Emergency Stop Lamp –This lamp will illuminate when the emergency stop button has been pressed or a critical engine fault has occured.

12.Diagnostic Display – This display monitors crtical engine functions. If any abnormal conditions occur, an Active Fault Code will be displayed. This diagnostic display can be located inside the control box.

13.Auto On/Off Engine Controller (MPEC) –

This controller has a vertical row of status LED's (inset), that when lit, indicate that an engine malfunction (fault) has been detected.When a fault has been detected the engine controller will evaluate the fault and all major faults will shutdown the generator.

During cranking cycle , The MPEC will attempt to crank the engine for 10 seconds before disengaging.

If the engine does not engage (start) by the third attempt, the engine will be shutdown by the engine controller’s Over Crank Protection mode. If the engine engages at a speed (RPM's) that is not safe, the controller will shutdown the engine by initializing the Over Speed Protection mode.

Also the engine controller will shut down the engine in the event of low oil pressure, high coolant temperature, low coolant level, and loss of magnetic pickup.These conditions can be observed by monitoring the LED status indicators on the front of the controller module.

A.MPEC Control Switch – This switch controls the running of the unit. If this switch is set to the OFF/RESET position, the unit will not run. When this switch is set to the MANUAL position, the generator will start immediately.

If the generator is to be connected to a building’s AC power source via an automatic transfer switch (isolation), place the switch in the AUTO position. In this position, should an outage occur, the automatic transfer switch (ATS) will start the generator automatically via the generator’s auto-start contacts connected to the ATS’s start contacts. Please refer to your ATS installation manual for further instructions for the correct installation of the auto-start contacts of the generator to the ATS.

B.Low Oil Pressure – Indicates the engine pressure has fallen below 15 psi. The oil pressure is detected using variable resistive values from the oil pressure sending unit. This is considered a major fault.

C.High Coolant Temperature – Indicates the engine temperature has exceeded 239°F. The engine temperature is detected using variable resistive values from the temperature sending unit. This is considered a major fault.

D.Overcrank Shutdown – Indicates the unit has attempted to start a pre- programmed number of times, and has failed to start. The number of cycles and duration are programmable. It is pre-set at 3 cycles with a 10 second duration. This is considered a major fault.

E.Overspeed Shutdown – Indicates the engine is running at an unsafe speed. This is considered a major fault.

F.Engine Running – Indicates that engine is running at a safe operating speed.
