3.3 Service Request Display
This led is designed to help the periodic maintenance of the genset 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 365
days).
The SERVICE REQUEST led has no effect on the genset
operation.
The DKG-705 has both programmable engine hours and maintenance time limit. The engine hours is
programmable between 0 and 2500 hours with 10-hour steps (P_624), the time limit is programmable between
0 and 2500 days with 10 day steps (P_625). If any of the programmed values is zero, this means that the
parameter will not be used. For example a maintenance period of 0 days indicates that the DKG-705 will
request maintenance only based on engine hours. There will be no time limit. If the engine hours is also
selected as 0 hours this will mean that the SERVICE REQUEST display will be inoperative.
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. The remaining engine hours and time to service may be checked on
the LCD display. (group_2, screen_7)
When the engine hours OR the time limit is over, the SERVICE REQUEST led (red) will start to flash.
To turn off the led, select programming mode, enter factory password and set the parameter_600 to 1, then
check the remaining time and engine hours to service using group_2, screen_7.
