Overview Engine Control Overview Many electronically controlled engines can be remotely operated by using an Analog throttle control signal. Some engine software must be configured for remote operation, check the engine application manuals for details. This programming should be accomplished whenever required for installing a remote throttle device.
PAGE 3
Interlocks Class1 provides a variety of engine controls that are used in a broad range of applications, therefore it is impossible for Class1 to determine the suitability of a particular control for any specific application. The flexibility of our products allows them to be used in a limitless number of custom applications. Class1 can advise you of the features that are available on a given product so that you can determine what product will meet your needs.

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.

Vernier Value Vernier Throttle Voltage/Resistance relationship by full turns. Readings taken from the Black wire (ground) to the Green wire (signal). Regulated 5 VDC is applied to the Red Wire for Voltage readings. This chart can be used to troubleshoot throttles in the field using the ground and 5 VDC supply from the engine ECM or Class1 Interface Module. Voltage readings provide more reliable information than resistance checks. Field readings should be within 5 % of those shown.
PAGE 8
High Idle If the Remote Throttle input is used for a high idle function, a potentiometer or voltage divider must be used to set the engine RPM (ECM signal voltage input). Figure (x) shows a simple layout for using a vernier control and a potentiometer to accomplish both a variable throttle and a high idle function using the remote throttle functions on the ECM. Remote Throttle Connections including High Idle for analog voltage signal and remote turn on function.
PAGE 9
Caterpillar Caterpillar has several engine models that are used in fire apparatus. The C-10 and C-12 engines along with the 3406E are identical for remote throttle and engine ECM connections. They are in the process of changing over to the HEUI configuration and the ECM connections will change from the 40 pin connectors (over and under) to the 70 pin side by side connectors used on the newer ECMs. The 3116 and 3126 engines have two variations.
PAGE 10
CAT Interface Caterpillar Engines require a Pulse Width Modulated (PWM) throttle signal. Class1 provides an interface that performs a conversion from a 0-5 VDC analog signal to a 12%-85% PWM signal (PN 100924).

DDEC Detroit Diesel DDEC III engine ECMs are ready to connect and operate without any extra programming. The remote throttle is called the Variable Speed Governor and the signal input is to ECM terminal D-1. Interlocking should be accomplished so that the circuit is grounded whenever the remote throttle should NOT be used. When the circuit is grounded, it is called 525 and when it is operational, it is called 510.
