2.7 Periodic Maintenance Request Display

This led is designed to help the periodic maintenance of the generator to be
made consistently.
The periodic maintenance is basically carried out after a given engine hours
(for example 200 hours), but even if this amount of engine hours is not
fulfilled, it is performed after a given time limit (for example 12 months).
The DKG-205 has both programmable engine hours and maintenance time
limit. The engine hours is programmable between 0 and 750 hours at 50-hour
steps, the time limit is programmable between 0 and 15 months. If any of the
programmed value is zero, this means that the parameter will not be used. For
example P19=200 and P20=0 means that DKG-205 will request maintenance
every 200 engine hours, but there will be no time limit.
The remaining engine hours and the remaining time limit are kept stored in a
non-volatile memory and are not modified by power supply failures.
When the engine hours or the time limit is over, the Periodic Maintenance
Request led (red) will start to flash. To turn off the led, the STOP key should
be held pressed for 10 seconds. In this case the digital display will show
'SER'.

2.8 Alarms

Alarms indicate an abnormal situation in the generating set and most of them
cause the engine to stop immediately.
If an alarm occurs, the related LED will turn on and if the alarm relay option is
selected, the alarm relay will be activated. If the ALARM MUTE key is
pressed, the alarm relay will be deactivated.
Except the emergency stop, alarm LEDs will stay on and disable the operation
of the generating set even if the alarm source is removed. In order to reset the
alarm condition, first choose OFF mode then resume to the previous mode of
operation.
CHARGE ALARM: It turns on in case of a charging alternator failure. This
alarm will not cause the engine to stop.
OVERLOAD ALARM: It turns on if a signal comes from the overload relay
output. This alarm will cause the generator to release the load, but the engine
runs until the end of the cooling period.
