INDUCEMENT STRATEGY
MRT 2150 Privilege Plus ST4 S2 / MRT 2550 Privilege Plus ST4 S2
Impacts and Actions by Operator
To ensure proper Tier 4 emission levels and to comply with the EPA and CARB regulations it has been implemented an inducement strategy
that will activate when emission related warnings occur. The following occurrences will trigger a warning indicator light:
• Low DEF Additive
• Insu cient DEF Additive Quality
• Faulty Elements of the Aftertreatment
In the case that inducement occurs again within 40 hours of engine operation, shortened inducement periods are activated.
Operators must:
- regularly check the gauge to make sure the DEF additive is at a proper level or
else engine inducement may occur;
- ensure in-time re lling with DEF additive;
- avoid any contamination of DEF additive with any other uids or debris;
- ensure re lls with properly stored DEF only.

With each transition of inducement state the buzzer
sounds for 5 seconds. In case of an override, the
buzzer sounds with a frequency of: 1 bpm.
EN
LOW: Maximum available torque is
reduced to 75% of peak torque across
the speed range and for a time interval
between 120 to 240 minutes.
SEVERE: Maximum available torque
will be reduced from 75 to 50% and for
a time interval between 240* a 265*
minutes.
Engine speed will be reduced to 60%
rated speed and for a time interval
between 240* a 265* minutes.
ULTRA
SEVERE: Maximum available torque
will be reduced from 50 to 20%, and
simultaneously engine speed will be
reduced to idle and for a time interval
between 265* a 290* minutes.
FINAL: The engine torque is limited to
a maximum of 20% across the whole
engine speed range and for a time
interval between 290* a 300* minutes.
The engine speed is limited to idling
speed and for a time interval between
290* a 300* minutes..
A maximum of 3 overrides for 30
minutes each is possible.
