ELECTRICAL / ELECTRONIC APPLICATION & INSTALLATION MANUAL
14.11 PTO Configuration - Remote Switches The Remote Switches Configuration utilizes a dedicated PTO On/Off circuit (connected to ECM Connector P1/J1, terminal 56), and an optional pair of PTO Switch On Lamps connected to terminal-30 (one in cab, the other out of the cab at the remote location - programming dependent). 14.11.1 One Speed Above Low Idle with PTO Switched On
Wiring Diagram 17 - “PTO Configuration Remote Switches with One Speed Above Idle Circuit” on page 59 is for applications requiring only one rpm above low idle. With PTO to Set Speed programmed to Yes, the ECM will ramp up to the pre-programmed PTO Engine rpm Set Speed when the PTO On/Off switch is ON. The engine will not exceed the PTO Engine rpm Set Speed with the PTO On/Off Switch ON. The Service Brake Pedal Position switch, Clutch Pedal Position switch, and cab accelerator pedal position sensor circuits are ignored whenever the PTO On/ Off switch is ON.
