General Information
Owner’s Manual for MLT6SMDS - MLT6SKDS Light Tower 23
• Warnings are non-critical alarm conditions and do
not affect the operation of the generator system.
They serve to draw the operator’s attention to an
undesirable condition. By default, warning alarms
are self-resetting when the fault condition is
removed.
• Electrical trips stop the generator in a controlled
manner. On initiation of the electrical trip condition,
the controller de-energizes all the outputs, includ-
ing the lights, to remove the load from the genera-
tor. Once this has occurred, the controller starts the
cooling timer and allows the engine to cool off-load
before shutting down the engine.
• Shutdown alarms stop the generator immediately.
On initiation of the shutdown condition, the control-
ler de-energizes all the outputs, including the lights,
to remove the load from the generator. Once this
has occurred, the controller shuts the generator set
down immediately to prevent further damage.
• 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 (If Equipped) .
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 2-26 . 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 2-26. Maintenance Screen
Event Log Screen
See Figure 2-27 . 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.
The log always contains the most recent shutdown
alarms.
Figure 2-27. Event Log Screen
Proceed as follows 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.
