Engine Connection Requirements

Caterpillar Engine Connection Requirements

This throttle signal configuration is known as a PWM or Duty Cycle. The EC300 sets the throttle signal duty cycle to approximately 9% at idle and 92% at full throttle. Generally, the EC300 is connected to the engine control at the connections designated for the “Primary Throttle Position Sensor” or “TPS”.

Depending on the model and harnessing provided, the EC300 Engine Harness

(J5) will either be connected to the “Primary Throttle Position Sensor” connector, or directly to the Customer Connector. See Table 14 and Table 15. Refer to the engine manufacturer’s literature to resolve any discrepancies.

Cummins Centry Engine Connection Requirements

The EC300 supports the Cummins Centry Type 8 engine controller. This controller is used on QSK, QSM-11, 485, 480C, and KTA type engines. The

KTA engine is configured for a current loop interface. All other types are voltage interfaces. The EC300 supplies approximately 1.1 volts at idle and 3.95 volts at full throttle when configured as a Cummins voltage output and 5.5 ma at idle and 19.8 ma at full throttle when configured as a Cummins current loop output.

All Cummins installations require pin one of J5 on the EC300 controller to be connected to J8, pin 2. A three pin GM Packard Weather Pack connector

(12010717) mates with the Cummins OEM throttle connector.

Cummins Quantum Voltage Type Engine Connection Requirements

This throttle signal configuration is a DC voltage. The EC300 throttle signal is set to approximately 0.1.1 VDC at idle and 3.95 VDC at full throttle. This configuration is typically used with Cummins QSM-11, 485C and QSK models with Quantum series engine controls. Generally, the EC300 is connected to the engine control at the connections designated for the throttle or throttle pot.

Depending on the model and harnessing, the EC300 wiring will connect to the

“Throttle” or the “OEM” connector. See Table17 and Table 18. Refer to the engine manufacturer’s literature to resolve any discrepancies.

Transmission State Signals

The EC300 provides complimentary transmission state signal outputs. These are optically isolated outputs capable of sinking or sourcing 50 mA of current, depending on the wiring configuration. The transmission in neutral output allows current to flow when the EC300 is commanding the transmission to neutral; the transmission in gear output is off in this state. Likewise, the transmission in gear output allows current to flow when the EC300 has engaged either the forward or reverse clutch; the transmission in neutral output is off in this state.

The options below depict the various wiring options for these outputs.

Refer to you enginie throttle interface specifications to see if these functions are compatable with your engine. These functions are set up by an Authorized

Twin Disc Distributor or at the factory.
