Once the vehicle has started, the system will continue
to charge the lead-acid batteries (B0) until the set point
conditions are met.
NOTICE: Idle Mitigation Mode will not be engaged until these
conditions are met.
•
To begin system operation, start the chassis engine.
•
The display will show the green Engine Running icon,
verifying the engine is running.
NOTICE: The lead-acid charging logic may prevent the engine
from shutting down until the charging criteria are satisfied.
•
Once the chassis has reached the base idle condition
and the lead-acid battery/batteries have reached the set
point, the countdown timer will appear. The default is
five seconds, but it may be set to a greater value upon
customer request.
NOTICE: The countdown can be overridden by pressing the
vehicle’s brake pedal to engage the Brake Override feature
(if equipped; see Section 3.2 for details).
•
When the countdown reaches 0, the engine will turn off
and the ZeroRPM logo will be displayed. The IMS will now
power the entire vehicle and will be ready to heat or cool.
