5 preset idle speeds (sub set of remote PTO)

This feature comes factory preset to the following 5 engine idle speeds 900, 1100, 1300,

1500, 1700 rpm's. They are attained by successively toggling the PTO switch on and off,

by doing so the idle s peeds will step through the preset speeds and will wrap back around

to the beginning set speed if the on/off switch is toggled enough times. These set speeds

can be changed to any speed between 900 and 2000 rpm's using a dealer service tool.

This will give the customer the ability to have multiple idle speeds to operate his/her

equipment.

Remote Throttle and Remote Throttle Switch

This feature allows the user of a continuously variable throttle. This throttle

potentiometer is power by the 5 volt supply and sensor return lines provided.

This feature is activated when the Remote Throttle Switch is On (closed to ground) and

the main throttle is closed. Remote Throttle does not require idle validation switches and

is not to be used for main vehicle accelerator.

Accelerator interlock

This allows the accelerator to be locked out when activated. This feature is often used in

conjunction with remote PTO or remote throttle. While active it disables the vehicles

accelerator pedal typically for safety reasons.

Switched Max Operating Speed

This feature selects a lower maximum engine speed when the switch is On (closed to

ground). The lowered engine speed is can be changed.

Switch Return

Electrical return/ground for switch circuits.

J1939 Interface

Cummins provides this interface to "gate" certain CAN messages for customer use. It is

an industry standard three way connector located underhood. Messages included are

vehicle speed, engine speed, park brake on/off, system voltage – filtered, brake switch

status, clutch switch engaged, wait to start lamp status and coolant temp.
