DDEC VI ELECTRONIC CONTROLS APPLICATION AND INSTALLATION
The CPC communicates over the J1587 and J1939 Data Links to the vehicle (see Figure 3-9).
Figure 3-9 NAFTA Architecture On-highway
Within the CPC, sets of data for specific applications are stored. These include idle speed,
maximum running speed, and speed limitation. Customer programmable parameters are also
stored here.
The CPC receives data from the operator (accelerator pedal position, switches, various sensors)
and other electronic control units (for example, synchronization controllers for more than one
genset, air compressor controls).
From this data, instructions are computed for controlling the engine and transmitted to the MCM
via the proprietary data link.

ENVIRONMENTAL CONDITIONS

Temperature, vibration, and water intrusion must be considered.

Temperature

The ambient operating temperature range is –40°F to 185°F (-40°C to 85°C).

Water Intrusion

The CPC is not water tight and cannot be subject to water spray. It must be mounted in an
enclosed, protected environment.
