Throttles
The basic input for most engines is a variable 0-5 VDC signal at the remote throttle input of the
ECM.
This input has various naming conventions and is manufacturer dependent.
DDC Variable Speed Governor (VSG)
CAT PTO Throttle Position (Multifunction Input #3)
CAT HEUI Accelerator Input (Remote Accelerator Position Sensor)
Cummins Remote Throttle Pedal Position Input
Navistar Remote Sensor Output
All of these will be referred to as “Remote Throttle Inputs” except in the individual engine
sections. With the exception of DDEC engines, all remote throttle applications must be pro-
grammed into the ECM. This can be performed using the appropriate engine software.
The remote throttle must be turned on in order to use it. This is a digital input for most engines
and should the point at which safety interlocking is performed.
DDC Switch from 525 to 510
CAT K999GN PTO ON/OFF switch (MFI#1)
Cummins Remote Accelerator Switch (Remote Throttle On/OFF switch)
Navistar 97CC Variable Enable
All engines except CAT provide a 5 VDC signal and a ground to be used with a remote throttle.
Installation consists of connecting the 5 VDC supply to terminal C on the throttle (Red Wire),
Signal Ground to terminal A (Black Wire) and the remote throttle input to terminal B (Green
Wire).
