Once this has occurred, the controller shuts the

•
DTC faults
are displayed by the controller.
To view the active alarms, repeatedly press the
↑
and
↓
buttons until the LCD window displays the alarm.
Continue to press the
↑
and
↓
buttons to cycle through
the alarms.
To exit the alarm screen, press the
↑
and
↓
buttons
simultaneously to enter the navigation menu. Once
entered, cycle to the desired operator screen.
NOTE:
The alarm condition must be corrected before a
reset will take place. If the alarm condition remains, it is
not possible to reset the unit. The exception to this is the
Low Oil Pressure alarm and similar ‘active from safety on’
alarms, as the oil pressure is low with the engine at rest.
To clear alarms that stop the generator, refer to
Resetting the Maintenance Alarms
.
NOTE:
The LCD backlight is on if the unit has sufficient
voltage while the unit is turned on, unless the unit is
cranking. In this case, the backlight is turned off.
If the controller is left in STOP mode for a period of
inactivity, the controller enters POWER SAVE mode. To
‘wake’ the controller, press the Stop (O) button.
Maintenance Screen
See
Figure 2-13
. The Maintenance screen (
) displays
the maintenance alarms configured into the controller.
The three alarms are for servicing the fuel filter, oil filter,
and air filter.
Figure 2-13. Maintenance Screen
Event Log Screen
See
Figure 2-14
. The controller’s event log (
) displays
a list of the last 15 recorded electrical trips or shutdown
events and the engine hours at which they occurred.
Once the log is full, any subsequent electrical trip or
shutdown alarm overwrites the oldest entry in the log.
Therefore, the log always contains the most recent
shutdown alarms.
Figure 2-14. Event Log Screen
To view the event log:
1.
Press both
↑
and
↓
buttons simultaneously to
display the navigation menu.
2.
Cycle to the event log section and press the Auto
button to enter.
3.
Repeatedly press the
↑
or
↓
buttons until the LCD
window displays the desired event.
Continuing to press down the
↑
or
↓
buttons will cycle
through past alarms. Eventually the most recent alarm
will display and the cycle begins again.
To exit the event log, press the
↑
and
↓
buttons
simultaneously to enter the navigation menu. Once
entered, cycle to the desired operator screen.
