VALVE GP-BRAKE CONTROL 1767800 - Caterpillar

C; Terminal 27)
The Lower Speed/Load contact connects to terminal 27 (discrete input C). When the 721 is in Speed Control Mode (terminal 32 open) and the Lower Speed/Load contact is closed, the control lowers speed at a rate determined by the Lower Speed Rate set point. When the contact is open, speed remains at its current value. Closing the Lower Speed/Load contact with the 721 in Speed Control Mode will cancel the ramps started by the Idle/Rated contact.When the 721 is in Load Control Mode (terminal 32 closed) and the Lower Speed/Load contact is closed, the control lowers the load at a rate determined by the Lower Load Rate set point. When the contact is open, load remains at its current value. Closing the Lower Speed/Load contact with the 721 in Load Control Mode will cancel the ramps started by the Unload/Reset to Rated and Base Load contacts.The Lower Speed/Load contact input is disabled when the remote speed/load setting mode is selected by closing both the Lower Speed/Load and Raise Speed/Load contacts.Raise Speed/Load Contact (Input D; Terminal 28)
The Raise Speed/Load contact connects to terminal 28 (discrete input D). When the 721 is in Speed Control Mode (terminal 32 open) and the Raise Speed/Load contact is closed, the control raises speed at a rate determined by the Raise Speed Rate set point. When the contact is open, speed remains at its current value. Closing the Raise Speed/Load contact with the 721 in Speed Control Mode will cancel the ramps started by the Idle/Rated contact.When the 721 is in Load Control Mode (terminal 32 closed) and the Raise Speed/Load contact is closed, the control raises the load at a rate determined by the Raise Load Rate set point. When the contact is open, load remains at its current value. Closing the Raise Speed/Load contact with the 721 in Load Control Mode will cancel the ramps started by the Unload/Reset to Rated and Base Load contacts.The Raise Speed/Load contact input is disabled when the remote speed setting mode is selected by closing both the Lower Speed/Load and Raise Speed/Load contacts.Failed Speed Signal Override (Input E; Terminal 29)
The Failed Speed Signal Override is connected to terminal 29 (discrete input E). When the contact is open, the control operates normally, reducing control output to minimum fuel in the event of a loss of speed signal.Closing the contact overrides the failed speed signal function, which may be required for start-up. Prior to engine start-up, the speed signal is nonexistent. On engines requiring fuel during cranking, the Failed Speed Signal Override allows the actuator to open and provide fuel for starting.Unload/Reset to Rated Contact (Input F; Terminal 30)
The Unload/Reset to Rated contact connects to terminal 30 (discrete input F). When the 721 control is in Load Control Mode (terminal 32 closed) and the Unload/Reset to Rated contact is opened, the load ramps to the Unload Trip Level at the rate determined by the Unload Ramp Time. When the Unload Trip Level is achieved, the Breaker
