The function is based on running hours. When the adjusted time expires, the controller will display an alarm. The running hours is
counting when the running feedback is present.
Set points available in menus 6110, 6120, 6300 and 6310:
• Enable: Enable/disable the alarm function.
• Running hours: The number of running hours to activate the alarm. The service timer alarm will be activated as soon as the
running hours have been reached.
• Day: The number of days to activate the alarm – if the running hours are not reached before this number of days, the alarm will
still be activated. The service timer alarm will be activated at 8:00 AM on the day the alarm expires.
• Fail class: The fail class of the alarm.
• Output A: Relay to be activated when the alarm is activated.
• Reset: Enabling this will reset the service timer to zero. This must be done when the alarm is activated.
6.13 Command timers
The purpose of the command timers is to be able to for example start and stop the genset automatically at specific times each
weekday or certain weekdays. If auto mode is activated, this function is available in island operation, load takeover, mains power
export and fixed power operation. Up to four command timers can be used for start and stop for instance. The command timers are
available in M-Logic and can be used for other purposes than starting and stopping the genset automatically. Each command timer
can be set for the following time periods:
• Individual days (MO, TU, WE, TH, FR, SA, SU)
• MO, TU, WE, TH
• MO, TU, WE, TH, FR
• MO, TU, WE, TH, FR, SA, SU
• SA, SU
INFO
To start in AUTO mode, the "Auto start/stop" command can be programmed in M-Logic or in the input settings.
INFO
The time-dependent commands are flags that are raised when the command timer is in the active period.
6.14 Oil renewal function
The purpose of the oil renewal function is to give the possibility to exchange a small portion of the lubricating oil of the engine with
fresh or new oil. This means that the quality of the oil is kept at a satisfactory level without significant degrading of the oil (for
example, contamination and TBN value) in the entire period between the oil changes.
The time interval between the oil changes is assumed to be 1000 hours of operation. The renewal function will read the engine
hours from the engine interface communication (EIC). The running hours counter in the controller is only used if the EIC counter is
not available.
The function in the controller is to activate a relay under defined conditions. Then the relay must be used for the oil renewal system
(not part of the DEIF scope of supply) where lubricating oil is removed and added to the engine. Any freely configurable relay is
available for this feature. In parameter 6890 a set point is available, which can be set between 1 and 999 hours to define when the
relay should close, and it is possible to choose which relay should be used. Furthermore, this parameter can be inversed, meaning
that the relay will remain closed until the set point is reached.
