ABOUT THIS MANUAL

This manual is designed to be used like any reference book. Please take a few moments to read and familiarize yourself with the basic operation of Optimized Idle.

An understanding of Optimized Idle concepts and terminology will be useful in obtaining the most benefit from this product. Brief definitions of the terminology used with Optimized Idle and throughout this manual can be found in the glossary.

SAFETY PRECAUTIONS

When active, the Optimized Idle system automatically stops and restarts the engine. The alarm will sound briefly prior to any Optimized Idle engine.

Optimized Idle User Manual

INTRODUCTION TO OPTIMIZED IDLE

Optimized Idle with DDEC software reduces engine idle time by running the engine only when required. Optimized Idle is a system which automatically stops and restarts the engine to accomplish the following:

• Keep the engine oil temperature between factory set limits

• Keep the battery charged

• Keep the cab/sleeper or passenger area at the desired temperature (using the optional thermostat)

Idle time and fuel savings information is available through DDEC Reports. Other benefits include overall reduction in exhaust emissions and noise, and improved starter and engine life (by starting a warm engine and eliminating starting aids). The system also reduces dead batteries due to electrical loads, such as refrigerators or satellite systems. Optimized Idle operates in one of two modes:

• Engine Mode

• Thermostat Mode (includes the same features as Engine Mode)

Engine Mode is used to keep the battery charged and the engine oil temperature between factory set limits. The Optimized Idle Active Light is illuminated whenever Engine Mode is active.

Thermostat Mode is used to keep the cab/sleeper (on--highway truck) and passenger area (coach) at the desired temperature and maintain the Engine Mode parameters. The optional thermostat must be turned ON for Thermostat Mode to be active. The Optimized Idle Active Light is illuminated whenever Thermostat Mode is active.

DDEC software allows the engine brakes to be turned on during shutdown. The amount of engine braking is determined by the dash--mounted engine brake switches. Braking during shutdown reduces cab shake.

OPERATING OPTIMIZED IDLE

The following conditions must be met to activate Optimized Idle:

• The ignition switch must be in the “ON” position and the engine idling

• Hood, cab, or engine compartment door(s) closed

• Transmission in neutral and in high--range (if equipped)

• Park brake set

• Idle Shutdown Timer must be enabled

NOTE: Keep vehicle park brake properly maintained.

If this vehicle is equipped with Cruise Control, the Cruise Master Switch must be moved to the “ON” position after the vehicle is idling and the above conditions are set. If the Cruise Master Switch is on prior to the vehicle idling, turn it to “OFF.” Turn the Cruise Master Switch to “ON” after the vehicle is idling and the above conditions are met.

NOTE: To disable Optimized Idle, turn off the ignition, turn the Cruise Master Switch OFF, or use the drive away feature (Section 6, Refer to section "DRIVE AWAY"). If the engine is not running, pressing the clutch (optional) will disable Optimized Idle. The Optimized Idle active light is on when Optimized Idle is active.

NOTE: The transmission lever should not be moved while Optimized Idle is active, since this could disable Optimized Idle. If the lever is moved, verify that the transmission is not in gear and that Optimized Idle is still active.

The engine compartment alarm sounds briefly prior to any Optimized Idle engine start. After Optimized Idle starts the engine, the speed will be increase to the parameterized target RPM (default = 1000, 900 if equipped with Clean Idle option). Once the above conditions are met:

• The Optimized Idle active light will flash

• The active light will stop flashing and stay on after the idle shutdown timer expires

The Optimized Idle active light flashing indicates that Optimized Idle will begin operation after the idle shutdown timer expires. When the active light stops flashing and stays on (after the idle shutdown timer expires) the operator can no longer use other DDEC features, including the foot pedal. This condition continues until the park brake is released, the hood or engine compartment door(s) is opened, the transmission is put in gear, or the Cruise Switch is turned off. Optimized Idle may continue to run the engine to warm--up the engine, or heat (cool) the interior. Optimized Idle will shut down the engine when the battery voltage, engine temperature, or cab temperature values are met. The engine will restart only when the ECM determines that the engine needs to start to charge the battery, warm the engine, or heat (cool) the interior.

Optimized Idle User Manual

ENGINE MODE

Optimized Idle will stop and restart the engine only as necessary, to keep engine temperature between 60°F (16°C) and 104°F (40°C) (factory set limits) and to keep the battery charged. When Optimized Idle starts due to low battery voltage (less than 12.2 V on a 12 V system, the engine will run for a minimum of two hours.

For Engine Mode to function, all of the conditions listed at the beginning of Section 3, Refer to section "OPERATING OPTIMIZED IDLE" must be met. Use the following procedure to start Engine Mode:

1. Start the engine and let it remain idling.

a. Close and secure the hood, cab or engine compartment door(s).

b. Put the transmission in neutral and in high-range (if equipped).

c. Apply the parking brakes.

2. If you have Cruise Control, turn the Cruise Master Switch to the "ON" position. If the switch is on, turn it off and on after the vehicle is idling.

3. The Optimized Idle active light flashes.

NOTE: If the engine does not start after the second Optimized Idle attempt, or if the vehicle moves while Optimized Idle is enabled, the Amber Warning Lamp (AWL) will turn on to indicate that Optimized Idle has been disabled (active light will turn off). The ignition must be turned to the "OFF" position, the engine restarted, and the conditions in the beginning of Section 3, Refer to section "OPERATING OPTIMIZED IDLE" met in order to enable Optimized Idle.

4. When the idle shut down timer expires, the Optimized Idle light will stop blinking and remain on. The engine will stop and restart as needed. Optimized Idle is now in Engine Mode.

THERMOSTAT MODE (WITH THE OPTIONAL OPTIMIZED IDLE THERMOSTAT)

This mode allows the operator to set the desired interior temperature and maintain Engine Mode parameters.

For additional thermostat features, Refer to section "THERMOSTAT OPERATION". The Optimized Idle thermostat is used to determine when the engine needs to restart to maintain the interior temperature. For Thermostat Mode to function, all of the conditions listed in the beginning of Section 3, Refer to section "OPERATING OPTIMIZED IDLE" must be met. Use the following procedure to start Thermostat Mode:

1. Start the engine and let it remain idling.

a. Close and secure the hood cab, or engine compartment door(s).

b. Put the transmission in neutral and in high-range (if equipped).

c. Apply the parking brake.

2. If you have cruise control, turn the cruise master switch to the "ON" position. If the switch is on, turn it off and on after the vehicle is idling.

3. The Optimized Idle active light flashes.

4. Set the heater or air conditioning to maximum. Set the heater or A/C fan controls on the dash and sleeper area to high. This will minimize engine run time.

5. Turn the thermostat on by pressing any button on the display.

6. Select cool or heat by pressing the buttons. This must match the setting on the heating and A/C controls set in step 4.

7. Set the desired interior temperature.

8. Optimized Idle will now stop and restart the engine, only when required, to keep the interior at the desired temperature. When the interior requires heating or cooling, the (heat) or (cool) icon will flash.

NOTE: If the engine does not start after the second Optimized Idle attempt, or if the vehicle moves while Optimized Idle is enabled, the Amber Warning Lamp (AWL) will turn on to indicate that Optimized Idle has been disabled (active light will turn off). The ignition must be turned to "OFF", the engine restarted, and the conditions in the beginning of Section 3, Refer to section "OPERATING OPTIMIZED IDLE"met in order to enable Optimized Idle.

9. When the engine starts, it will ramp up to increase to the parameterized target RPM (default = 1000, 900 if equipped with Clean Idle option) and the fan and accessories will turn on approximately 30 seconds after the engine starts. To turn off the thermostat and exit the Thermostat Mode, press and hold the mode button for 3 seconds. Optimized Idle is now in Engine Mode.

Optimized Idle User Manual

Continuous Run Condition and Extended Idle Condition

Under normal conditions, the engine will cycle on and off to keep the interior at the desired temperature. Two automatic conditions which help keep the operator comfortable and reduce engine cycling are described in the next sections.

Continuous Run Condition

This condition allows the engine to run continuously if the outside temperature parameter exceeds the parameterized limits (hot and cold) and the thermostat set point can not be met (factory default is 25°F (-4.00°C) for cool mode and 90°F (32°C) for heat mode). When the thermostat is in the Continuous Run Condition, the temperature icon will flash along with the heat or cool icon.

Extended Idle Condition

NOTE: If Optimized Idle enters the extended idle condition, it may be an

indication that the heat or cool setting on the thermostat does not match the vehicle heating or cooling system setting. It could also be an indication of low freon, blockage in the heater system, or system tampering.

If the Continuous Run Condition is not needed and the thermostat set point is not met within 45 minutes, the engine will shut down for 15 minutes, restart and run for 15 minutes. This 15 minute on and off cycle will continue until the thermostat set point is reached or until the thermostat is turned off.
