SEQUENCING
These generators are capable of sequencing for control
of balanced maintenance schedules. As described
above, these generators can start and stop as demand
raises or lowers. In addition, if the units get to the point of
maintenance, it will ramp off and start the next generator to
relieve it based on the time remaining on the maintenance
timer.
After maintenance is performed, the maintenance timers
should be reset to the recommended service interval. This
is usually 250 hours depending on the engine oil type.
MAINTENANCE INTERVAL
Maintenance intervals are factory set for 250 hours.
The maintenance interval timer will count down to zero
indicating that it is time for the unit to be serviced.
Once the timer counts down to zero, a pre-alarm will appear
indicating that the unit is due for maintenance. To reset the
maintenance interval back to the default time of 250 hours,
press and hold the “Reset” button for ten seconds.
To reset the maintenance interval using the reset button,
the Maintenance Due pre-Alarm must be active, and the
Basler controller must display the “Overview Screen” (Main
Screen).
If the maintenance timer has not yet expired and it is
desired to reset the unit back to 250 hours, navigate back
to the settings menu. Settings Menu->System Parameters-
>Engine Statistics->Hours To Maintenance.
