9.3.2 Request system
MAN Marine request system
During operation after the ignition was switched
on, the aftertreatment system is continuously
monitored for correct operation and function.
The Marine request system of the aftertreatment
system automatically comes into effect if correct
regulation of NOx emissions is not possible or is
imminent. Upon detection of incorrect regulation,
the Marine request system automatically switches
to the emissions error page; this means that the
operator is warned and/or alarmed about the
incorrect regulation of NOx emissions by a visual
flashing message and an additional acoustic signal
(intermittent).
Notice:
In the event that an engine and aftertreatment
error occur simultaneously, the error page of
the engine is displayed as having higher priority.
The operator can switch to the error page of the
aftertreatment system at any time
Display:
Upon detection of incorrect regulation of NOx emissions the display automatically switches to the
emissions error page (engine or emissions). Here, the operator is informed or warned about incorrect
regulation of the NOx emissions via a flashing message. The flashing message changes to a permanent
static message by pressing the [OK] button. At any time, the operator can access a different or the
previously used user interface, the previously-detected message remains active.
By activating the flashing active symbol “Exhaust emissions” [ ] the user returns to the emissions
message user interface. The number of pending errors is displayed to the user next to the “Exhaust
emissions” symbol.
The pending prompt cannot be reset until it is remedied. The prompts can only be confirmed by the
operator via the confirmation button [OK].
