The power module can be used as a stand-alone unit to power an isolated load. Manual operation refers to manually closing the generator breaker using the circuit breaker switch. The following information describes the steps for manual operation in the single unit mode.
- 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.
The pre-startup procedures are to be performed by qualified personnel. Perform the following steps before the unit is started.
Install the "lead unit jumper". The lead unit jumper is connected between terminals 93 and 94 in the customer connection box. The jumper is required in order to allow the generator breaker to close in the single unit mode manual operation mode.
- Press the "RUN" button that is on the EMCP 4.4.
Note: The engine will begin to start immediately.
- Use the EMCP 4.4 display to observe the generator voltage and the frequency once the engine is running at the rated speed.
Note: The sync mode setting in the EMCP 4.4 will automatically change to "check" mode when the EMCP 4.4 powers up. Additionally, the sync mode setting will automatically change to "check" mode whenever the EMCP 4.4 "STOP" button is pressed. "Check"mode causes automatic generator-to-bus synchronization (not applicable in "single unit mode") but requires manual closing of the generator breaker using the circuit breaker switch.
Note: Manual voltage and/or frequency adjustments are unrestricted in this method of operation.
- If the EMCP 4.4 sync mode switch has been changed to "manual mode", make necessary voltage and/or frequency adjustments using the EMCP 4.4 control screen interface. Otherwise go to step 4
- Use the circuit breaker switch to close the generator breaker at the desired time. Rotate the handle clockwise until the breaker closes, then release the handle. After the handle is released, the generator unit will be providing power for 100 percent of the load.
- Press "STOP" button that is on the EMCP 4.4.
Note: The generator breaker will open immediately. The engine will continue to run in cool down mode until the cool down time has elapsed. The engine will shut down after the cool down time has elapsed.
The power module can be used as a stand-alone unit to power 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 in single unit mode.
- 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.
The pre-startup procedures are to be performed by qualified personnel. Perform the following steps before the unit is started.
- Install the "lead unit jumper". The lead unit jumper is connected between terminals 93 and 94 in the customer connection box. The jumper is required in order to allow the generator breaker to close in the single unit mode automatic operation mode.
- Install the required wiring from the remote run request contact to terminals B- and RR if automatic remote start is required.
Note: The remote run request contact is controlled by the automatic transfer switch or by other customer supplied controls.
- Press the "AUTO" key that is on the EMCP 4.4.
Note: For automatic breaker close control, the generator breaker control switch must be in the "normal" position (not in "trip") and either red or green flagged.
- The engine will start when the remote run request contact is closed.
- After the engine is running at the rated speed, the generator breaker will close automatically.
Note: Alternatively, the unit can be started by first placing the EMCP 4.4 sync mode switch in "auto" mode before pressing the "RUN" button on the EMCP 4.4. The generator breaker will close automatically once the unit is up to rated voltage and frequency.
- After the engine is running at the rated speed, the generator breaker will close automatically.
- The generator unit is now providing power for 100 percent of the load.
Press the "STOP" button that is on the EMCP 4.4 control panel or open the remote run request control to initiate a normal shutdown.
Note: The generator breaker will open immediately. The engine will continue to run in cool down mode until the cool down time has elapsed. Once the cool down delay has elapsed, then the engine will shut down.
