GENERATOR CONTROL PANEL

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 a 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 conn ected 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 geerator to the ATS.

Low Oil Pressure — Indicates the engine pressure has fallen below a safe operating level. The oil pressure is detected using variable resistive values from the oil pressure sending unit. This is considered a major fault.

High Coolant Temperature — Indicates the engine temperature has exceeded a safe operating level. The engine temperature is detected using variable resistive values from the temperature sending unit. This is considered a major fault.

Overcrank Shutdown — Indicates the unit has attempted to start a pre- programmed number of timesand 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.

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

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

Located behind the generator control panel is the Generator Control Box. This box contains some of the necessary electronic components required to make the generator function.

The Control Box is equipped with the following major components:

Over-Current Relay

Voltage Rectifi er (AVR)

Starter Relay

Current Transformer

Voltage Change-Over Board

Three Phase Circuit Breaker

NOTICE

Remember the overcurrent relay monitors the current

flowing from the U,V, and W Output Terminal Lugs to the load.

In the event of a short circuit or over current condition, it will automatically trip the 800 amp main breaker.

To restore power to the Output Terminal Panel, press the reset button on the overcurrent relay and place the main circuit breaker in the closed position (ON).
