6.10 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 12 months).
The SERVICE REQUEST led has no effect on the genset
operation.
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
SERVICE REQUEST
led (red) will start to
flash and the service request relay function will be active.
The service request relay function may be assigned to spare relays using
Relay Definition
program parameters. Also relays on an extension module may be assigned to this function.
To turn off the SERVICE REQUEST led, and reset the service
period, press together the ALARM MUTE and LAMP TEST keys
for 5 seconds.
