30 Owner’s Manual for Mobile Generator
Operation
NOTE: The controller can be started from any screen
when it is in MANUAL mode.
4. Pressing the green engine start (I) button on the
controller will initiate the startup procedure and
start the engine, if there are no engine faults
preventing the unit from starting.
NOTE: It may take a few seconds for the engine to run
smoothly and reach its governed operating speed. During
this time, the screen will show a voltage different from the
voltage set with the voltage selector switch.
5. If the engine does not start after the first cranking
attempt, the engine will pause for 15 seconds to
allow the starter to cool. The display screen will
show MANUAL MODE - CRANK REST at the top
of the screen. The engine will make two more
attempts to start for a total of three crank cycles.
6. If the engine does not start and run within three
crank cycles, the display screen will show the fail to
start alarm. The starting sequence can be repeated
after the starter has had a minimum of two minutes
to cool. Pressing the ENTER () button will clear
the alarm and reset the controller.
NOTE: The engine controller may skip the preheat
engine steps on some of the larger models.
7. Once the engine starts, it begins speeding up to a
constant 1800 RPM. The engine may hunt or
change speeds until operating speed is reached.
The engine will be warmed up and the operator
screens will show engine and generator operating
parameters after a few minutes of operation.
8. Check the generator for excessive noise or
vibration and any coolant, oil, or fuel leaks before
applying any loads.
9. Verify the AC output voltage is correct. See Fine
Voltage Adjustment.
10. Verify the frequency (Hz) is correct on the
generator screen. The frequency should read
approximately 60 Hz with no loads connected to
the generator, depending on the type of engine
governing used.
11. If all wiring connections have been made correctly,
switch the main circuit breaker to ON (I), and then
add any loads attached to the receptacles by
switching the respective circuit breaker to the ON
(I) position. A slight change in engine sound when
a load is applied to the unit is normal.
AUTO (Remote) Starting the Unit
AUTO mode 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. Review
the Pre-start Checklist and Manually Starting the Unit
before putting the unit in AUTO mode. Follow all safety
warnings and review all information on isolating the
generator with a transfer switch if the unit is to be used as
a standby power supply. See Changing Exercise
Timers, then proceed as follows:
1. Perform a manual start of the unit at least once to
verify the engine is operating correctly.
2. To check the remote start circuit, remove the wires
from the remote start terminal block. Press the
AUTO/MANUAL mode ( ) button, and the display
screen will show auto mode at the top of the
screen.
3. Attach a jumper wire (minimum 16 gauge) across
the two terminals on the remote start terminal
block. This applies a ground to the controller to
close the starting circuit contacts. The engine will
crank, start, and run.
4. 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.
5. Verify the unit is in AUTO mode. The display
screen should show AUTO mode at the top of the
screen.
6. Secure the unit by closing and locking all access
doors.
7. The unit is now ready for remote starting.
See Figure 3-2. The remote start terminal block provides
a connection for installation of a remote start switch
which will allow the unit to be started by a remote dry-
contact closure switch. For location of the remote start
terminal block, see Genset Controller.
Before entering AUTO mode, verify the contacts on any
remote switch linked to the unit are open. If the contacts
on a remote switch are closed, the engine will crank and
start when AUTO mode is entered. Attach the switch
leads to the two unused terminals (A) on the unit’s
remote start terminal block.
