Generator Control Panel

Figure 4. Generator Control Panel

The deﬁ nitions below describe the controls and functions of the Generator Control Panel (Figure 4).

1.Pilot Lamp — Indicates the system is running.

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.AC Voltmeter — Indicates the output voltage present at the U,V, and W Output Terminal Lugs.

4.Frequency Meter — Indicates the output frequency in hertz (Hz). Normally 60 Hz.

5.AC Ammeter — Indicates the amount of current the load is drawing from the generator per leg selected by the ammeter phase-selector switch.

6.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.

7.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. This switch does not effect the generator output in any fashion, it is for current reading only.

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

9.Voltage Regulator Control — Allows ±15% manual adjustment of the generator’s output voltage.

10.Main Circuit Breaker — This three-pole, 800 amp main breaker is provided to protect the U,V, and W Output Terminal Lugs from overload.

11.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.
