14.3.5 Final Inducement Safe Harbor Mode.
Safe harbor mode is a mode of operation that allows for full engine torque
capability post Inducement Level 3 activation for a limited time period. This
strategy is designed to allow a machine that has been forced to low idle or
shutdown due to a system failure causing a Level 3 inducement to be moved
to an area where re work can take place.
Once the final inducement has been completed (section 14.3.4.1) the first
ignition key switch cycle after this event will enable the safe harbor strategy.
Once active the following applies;
•
Strategy is active for 20 minutes only and timer is
NOT
reset by cycling
the ignition key switch.
•
During the 20 minutes of safe harbor mode the engine can be turn off
and re started as many times as required
•
After 20 minutes the engine will revert back to Level 3 inducement
handling i.e. 5 min cooldown at Low idle with 50% Torque reduction
then shutdown or idle.
Note: Safe harbor mode does not apply to DEF Level Inducements.
14.3.6 Engine First Fit Inducement Activation
To ensure Inducement diagnostics are not false triggered during machine
assembly the 1204F and 1206F product range are shipped with Inducements
disabled. No ET configuration is required to enable the engine inducements
once machine assembly has been completed. The automatic enablement of
the Inducement strategy is based on either of the following criteria being met.
•
Engine running exceeds 25hrs (initiated from first engine start and does
not reset on key cycle)
•
System has been detected (by Engine control system) as fault free for
2hrs of engine running time.
Note: In order to protect the 1204F DEF cooled injector from damage due
to a lack of DEF fluid or disabled dosing system the engine will invoke a
100% engine derate once the engine exhaust SCR Inlet temperature
exceeds 200DegC. This code will remain active until the fault is fixed or
an ignition key cycle is performed.
14.3.7 Emergency Inducement Override Strategy
At present this strategy is under development and at the time of writing the
machine interface requirements have not yet been approved.
