10. Once the engine starts it will immediately begin speeding up to a constant 1800 rpm. On units with isochronous engine governing, the engine may hunt or change speeds until operating temperature is reached. After a few minutes of operation, the engine will be warmed up and the LCD window will show engine and generator operating parameters. Temperature will be shown as “0” until the engine temperature is approximately 100° F.
11. Once the generator is at normal operating temperature, check the generator for excessive noise or vibration and any coolant, oil or fuel leaks before applying any loads.
12. Check that the AC output voltage is correct. The output voltage can be fine adjusted by using the fine voltage adjustment screw (rheostat), as described on page 14.
13. Check that the frequency (Hz) is correct. With no loads connected to the generator, the frequency should read approximately 60-62 Hz, depending on the type of engine governing used.
14. If all wiring connections have been made correctly, switch the main circuit breaker to the “ON / I” position and then add any loads attached to the convenience outlets by switching the respective circuit breaker to the “ON / I” position. You will notice a slight change in engine sound when a load is applied to the unit.
“AUTO” (REMOTE) STARTING OF THE GENERATOR
The “AUTO” button is used when the generator is started from a location other than the control panel and by using a dry-contact closure remote start switch (transfer switch). “AUTO” (remote start) is the normal setting when the generator is being used as a standby power supply. Before putting the generator in the “AUTO” mode, review the
Pre-Start Check List and Manual Starting of the Generator sections beginning on page 15. Also follow all safety warnings and information on isolating the generator with a transfer switch if the unit is to be used as a standby power supply described on pages 27-28 . Then continue with the steps described below:
1.
Perform a manual start of the generator at least once to verify that the engine is operating correctly.
2.
If a check of the remote start circuit is desired, remove the wires from the remote start terminal block.
Press the “AUTO” button, the Liquid Crystal Display (LCD) window should highlight “AUTO” in the upper left corner. Attach a jumper wire (minimum 16 gauge) across the two terminals on the remote start terminal block. This applies a ground to the Magnum Digital Controller (MDC) to close the starting circuit contacts. The engine should crank, start and run.
3.
Remove the jumper wire from the remote start terminal block and the engine will stop. Reconnect any necessary wires from the remote start switch (transfer switch) to the remote start terminal block.
4.
Confirm unit is in “AUTO” mode. The LCD window should have “AUT” highlighted in the upper left corner.
5.
Close (set to “ON / I”) the main circuit breaker.
6.
Secure the generator by closing and locking all access doors.
7.
The generator is now ready for remote starting.
SHUTTING DOWN THE GENERATOR
Check with personnel using power supplied by the generator and let them know that the power is going to be turned off. Make sure the power shutdown will not create any hazards by accidentally turning off equipment that needs to be kept on (pumps, compressors, lights, etc.).
1.
Remove all loads from the generator by opening (turn to OFF / “O”) all circuit breakers.
2.
Let the engine run for approximately five minutes to allow it to cool down.
3.
Push the red “ENGINE STOP” button. Pressing “Engine Stop” will result in the generator going into the shutdown cycle and starting a 15 second shutdown timer called “Stop Value”. If the unit does not shutdown within 15 seconds a “Stop Fail” alarm will be displayed on the Liquid Crystal Display (LCD) window.
4.
Move the “CONTROL ON / I” toggle switch to the “CONTROL OFF / O” position.
