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 12 months).
The unit has both programmable engine hours and maintenance time limit. The engine hours is
programmable with 50-hour steps, the time limit is programmable with 1 month steps. If any of the
programmed values is zero, this means that the parameter will not be used. For example a maintenance
period of 0 months indicates that the unit 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.
When the engine hours
OR
the time limit is over, the A14-
SERVICE REQUEST
warning will
occur and the service request relay function will be active.
The service request relay function may be assigned to the auxiliary relay using
Relay
Definition
program parameter.
The remaining engine hours and the remaining time limit are kept stored in a non-volatile memory
and are not affected from power supply failures.
The time and engine hours to service are displayed by pressing the MENU button.
The unit features a non-erasable incremental engine hour meter. The hour meter information is
kept in a non-volatile memory and is not affected from power supply failures.
The engine hours may be displayed by pressing the MENU button.
Some additional features are installed within consecutive software releases. In order to be
sure of the validity of the status of the unit, the software version needs to be known.
The software version may be displayed by pressing the MENU button.
To turn off the SERVICE REQUEST led, and reset the service
period, press the STOP key for 5 seconds.
The SERVICE REQUEST warning has no effect on the
genset operation.
