Engine Idle Limiting

Idle Shutdown Timer

This feature is an optional 1- to 100-minute idle shutdown system with a timer on the driver display screen. Its purpose is to conserve fuel by eliminating excessive idling. Idle shutdown timing and parameters are programmable. See the engine manufacturer's operation manual for specific details for your vehicle.

Power Takeoff (PTO) Governor

WARNING
To avoid injury, do not install a PTO that is not Detroit Diesel approved onto a Detroit™ Transmission. Use of a non-Detroit Diesel approved PTO with a Detroit Transmission could result in unintended operation which could lead to severe personal injury.
Engine power takeoffs (PTO) tap into engine power to run auxiliary devices, such as hydraulic pumps that power additional equipment.
The following are general guidelines for operating a PTO.
1.
Set the parking brake and put the transmission in neutral.
2.
Press the dash PTO switch. Release the switch when the light begins to blink.
2.
When the light illuminates steadily, the PTO is engaged and ready to operate. In stationary mode, the vehicle must remain in neutral with the parking brake set.
3.
To activate mobile mode, depress the service brake pedal, then shift from neutral to reverse, 1st, or 2nd gear. The clutch opens and the PTO disengages for a moment.
4.
Touch the accelerator pedal to close the clutch and engage the PTO in mobile mode. The PTO may be operated with the transmission in neutral or reverse, and 1st and 2nd gears only.
NOTE: Do not attempt to change gears while the vehicle is moving. The transmission ignores the request.
5.
To deactivate mobile mode, bring the vehicle to a stop. The clutch opens and shuts down power to the PTO.
6.
To resume stationary mode, shift to neutral. The PTO engages.
7.
To deactivate PTO, press the PTO switch again. When the light in the switch goes out, power to the PTO is shut off.

PTO Instrumentation Unit Controls

If configured for ICU speed control, PTO screens can be accessed under the Vehicle Settings menu.
NOTE: Speeds shown are representational only. Actual speeds are determined by the vehicle's parameters.
Fig. 11.1, Quick Access Screen: Power Take Off (PTO)
After the Power Take Off (PTO) is engaged using the PTO switch, available PTO speeds are indicated by check boxes on the Power Take Off Screen in the instrumentation unit. See Fig. 11.1.
PTO speed 1 is selected initially. If a speed is out of range it is not available to select. If a PTO speed is available for customization, it is indicated with a Customize option.
