11. Check the unit 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). Refer to
13. Check that the frequency (Hz) is correct. With no loads connected to the generator, the frequency should read
approximately 60 Hz, depending on the type of engine governing used.
14. If all wiring connections have been attached and secured correctly, switch the main circuit breaker to the ON (I)
position and then add any loads attached to the receptacle panel receptacles 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 UNIT
The Auto button is used when the unit is started from a location other than the control panel by using a transfer
switch. Auto (remote start) is the normal setting when the unit is being used as a standby power supply. Before
putting the unit in the Auto mode, review the
page
27. 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. Refer to
described below:
1. Perform a manual start of the unit 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 LCD window should highlight "AUT" 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 the unit is in Auto mode. The LCD window should have "AUT" highlighted in the upper left corner.
5. Close the main circuit breaker (set to the ON (I) position).
6. Secure the unit by closing and locking all access doors.
7. The unit is now ready for remote starting.
AUTOMATIC SHUTDOWN
This unit is equipped with a low oil pressure and high coolant temperature automatic shutdown system. This system
will automatically shut off the fuel supply to stop the engine if oil pressure drops too low or the engine exceeds normal
operating temperature. Return the Control Power switch to the OFF (O) position to reset the unit after you have
determined the cause of the shutdown.
LIGHT OPERATION
NEVER operate the lights without the protective lens cover, or with a lens cover that
is cracked or damaged. The bulbs in the light fixtures produce high temperatures and
operate under pressure. A broken or missing lens cover could cause the bulbs to
