DCA-100SSJU — ENGINE OPERATING PANEL (WITH MPEC)
The definitions below describe the controls and functions of the
1.Panel light - Normally used in dark places or at night. When activated, panel will luminate. When the generator is not in use, turn the panel light switch to the ‘OFF’ position.
2.Panel light switch- When activated, will turn on control panel light.
3.Oil Pressure Gauge – Normal operation should be about 25 psi. When starting the generator the oil pressure may read a bit higher, but after the engine warms up the oil pressure should return to normal.
4.WaterTemperature Gauge – During normal operation
been detected the MPEC 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 MPEC's " Over Crank Protection" mode. If the engine engages at a speed (RPM's) that is not safe, the MPEC will shutdown the engine by initializing the "Over Speed Protection" mode.
Also the MPEC will shutdown the generator 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 MPEC module.
this gauge be should read between 165oF to 215oF.
5.Charging Ammeter Gauge – Indicates the current being supplied by the engine’s alternator which provides current for generator’s control circuits and battery charging system.
6.Fuel Gauge - Indicates amount of diesel fuel available.
7.Tachometer – Indicates engine speed in RPM’s for 60 Hz operation. This meter should indicate 1800 RPM’s when the rated load is applied. In addition a built in hour meter will record the number of operational hours that the generator has been in use.
8.Engine speed Handle- This handle will change the speed of the engine from high to low.
A.Off/Manual/Auto Switch – This switch controls the running of the generator. If this switch is left in the "OFF" position, the generator 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 a transfer switch (isolation), place the switch in the auto position. In this position the generator will monitor the AC line output from the building's power source.
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.

10.MPEC – Microprocessor Engine Control Module – (MPEC) has a vertical row of status LED's (Figure 11), that when lit, indicate that an engine malfunction (fault), has been detected. When a fault has

C.High Coolant Temperature – Indicates the engine temperature has exceeded 215° 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 preset 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.
