The definitions below describe the controls and functions of the DCA-220SSK " Control Panel " (Figure 9).

1.Frequency Meter – Indicates the output frequency in hertz (Hz). Normally 60 Hz ±1 Hz .

2.AC Ammeter – Indicates the amount of current the load is drawing from the generator.

3.Ammeter Change-Over Switch – This switch allows the AC ammeter to indicate the current flowing to the load connected to any phase of the output terminals, or to be switched off.

4.AC Voltmeter – Indicates the single phase output voltage present at the UVW terminals.

5.Voltmeter Change-Over Switch – This switch allows the AC voltmeter to indicate phase to phase voltage between any two phases of the output terminals or to be switched off.

6.Pilot Lamp – Indicates that the generator is working properly.

7.Main Circuit Breaker – This three-pole, 600 amp main breaker is provided to protect the UVW voltage output terminals from overload.

8.Voltage Regulator Control – Allows manual adjustment of the generator’s output voltage.

9.Panel Light – Normally used in dark areas or at night time. When activated, panel lights will illuminate. When the generator is not in use be sure to turn the panel light switch to the OFF position.

10.Panel Light Switch – When activated will turn on control panel light.

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

shutdown the generator. Figure 10. MPEC Module

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.

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.

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.Typical programmable start settings is 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.
