Automatic Operation
The power module can be used in parallel with other units to provide power for an isolated load. Automatic operation refers to the use of the on-board control system to close the generator breaker automatically. The following information describes the steps for automatic operation.
Ensure that all load cable connections have been correctly made.
Verify that the unit can be safely started.
Verify that power can be applied to the load. Pre-startup Procedures
Install wiring from the remote run request contact. Note: The remote run request contact is controlled by the automatic transfer switch or by other customer supplied controls.
Press the EMCP 4.4 "AUTO" key in each unit so that all units are in "AUTO" mode. Note: The sync mode setting in the EMCP 4.4 will automatically change to "AUTO" whenever the EMCP 4.4 is put in "AUTO" modeNote: For automatic breaker close control, the generator breaker control switch must be in the normal position (not in trip).Startup Procedure
All units can be started simultaneously using a remote run request contact.
After the lead unit is running at rated speed, then the generator breaker will close automatically to a dead bus.
All of the other units will automatically synchronize and then close to the live bus. Note: Alternatively, each unit can be started individually, beginning with the lead unit, first placing the EMCP 4.4 sync mode switch in "auto" mode. After placing the EMCP 4.4 sync mode switch in "auto" mode, press the "RUN" button on the EMCP 4.4. The generator breaker will close automatically once the unit is up to rated voltage and frequency and synchronized with the bus.The paralleled units now power the load and share the load proportionally.Shutdown Procedure
Any of the methods below will initiate a normal shutdown:
If a remote run request contact is used to start the units, then open the contact in order to put all units in stop/cooldown.
Press the "STOP" button that is on the EMCP 4.4 in each unit to put all units in stop/cooldown. Note: First, verify load level permits unit shutdown without over-burdening the remaining paralleled units.Note: Pressing "STOP" begins ramping down generator output. At the programmed kW trip level, the breaker will automatically trip open and engine will go into cooldown.Generator Circuit Breaker
The generator circuit breaker is a 100% rated universal power circuit breaker. The generator circuit breaker is designed to protect electrical systems from damage caused by overloads, short circuits, and equipment ground faults. The circuit breaker is designed to open and close a circuit electrically. The circuit breaker is designed to open the circuit automatically at a predetermined over current setting.The generator circuit breaker is operated via a stored energy mechanism. The stored energy mechanism can be charged manually or charged by using a motor. The closing time is less than five cycles. Closing and opening operations can be initiated by electrical signals.Closing the Breaker
The generator circuit breaker can be closed automatically when running in the "AUTO" mode or manually with the circuit breaker switch in the "RUN" mode. All of the
