Control and operation
92
Read this manual carefully before starting any work!
This is particularly applicable to the chapter “General Safety Instructions”
and the respective safety instructions in the chapters.
Acoustic signal:
Upon detection of incorrect regulation of NOx emissions, the operator is informed by an additional
intermittent acoustic signal. The acoustic signal is permanently interrupted by pressing the confirmation
button [OK]. The acoustic signal can be temporarily (15-minute interval) interrupted via the Mute button
[SHUT OFF HORN]. Interruption of the acoustic warning system is necessary due to safety risks, since
an acoustic warning could drown out the environmental noises.
The prompt occurs if correct regulation of NOx emissions by the following components is not possible:
S
DEF/AdBlue
®
/AUS32/AUS40
- Tank fill level empty
- Insufficient quality
S
Aftertreatment system
- Error
- Manipulation
DEF/AdBlue
®
/AUS32/AUS40 tank fill level
The DEF/AdBlue
®
/AUS32/AUS40 tank fill level is determined by a fill level sensor. The operator is warned
if the filtered DEF tank fill level reaches the specified limit values (see following table). To prevent engine
operation without DEF/AdBlue
®
/AUS32/AUS40 and the consequential increase in NOx emissions, the
DEF/AdBlue
®
/AUS32/AUS40 tank must be refilled.
DEF tank level Action steps
≤ 20 % Warning:
low fill level
(low level) Reason Fill level is lower than 20 % of the overall volume
Reaction Acoustic and visual prompt on operator display
Correction The operator should top up the DEF tank
≤ 10 % Warning:
empty tank
(empty level) Reason Fill level is lower than 10 % of the overall volume
Reaction Acoustic and visual prompt on operator display
DEF tank almost empty
Correction The operator must top up the DEF tank
Empty* Alarm:
empty tank
(empty level
alarm) Reason DEF fill level is 0 % of the overall volume
Reaction Acoustic and visual prompt
No DEF/AdBlue
®
/AUS32/AUS40 dosed in
→ increased NOx emissions
Entry in the emissions history memory
Correction The operator must immediately refill the DEF tank. In
addition, the operator must implement further measures in
accordance with U.S. EPA Title 40 CFR 1042.660
(see page 93)
*Notice:
If the tank fill level is detected as “empty” (0 %), there is still a residual amount in the tank and in the
system that is used to cool and lubricate the aftertreatment system. All tank fill levels are based on the
usable quantity that is available for dosing.
