DCA-300SSK — GENERATOR CONTROL PANEL

The definitions below describe the controls and functions of the DCA-300SSK “Control Panel” (Figure 8).

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

2.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.

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

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

5.AC Voltmeter – Indicates the single phase output voltage present at the UVWO terminals.

6.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.

7.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.

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

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

10.MicroprocessorEngineController(MPEC S/N3701674~) 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. Any major fault will cause the controller to 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 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 controller 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.

11.Main Circuit Breaker – This three-pole, 800 amp main breaker is provided to protect the UVWO voltage output terminals from overload.
