DGC-2020HD Typical Applications
Governor PWM Output Connections
The Governor PWM output allows interfacing with select CAT control systems. Governor PWM output
connections are shown in Figure 3-25.
1. PWM wiring should be as short as possible and should only be
used in applications where the DGC-2020HD is mounted on the
machine in the same general location as the device being driven
by the PWM signal.
2. If the DGC-2020HD is not located close to the engine, it is
recommended to employ a device to convert analog signals to
PWM signals located close to the device being driven by the PWM
signal. The DGC-2020HD GOV output should be configured for
analog output control to drive the device that converts analog
signals to PWM signals.
3. Twisted shielded pair wiring is suggested for all analog and PWM
control signals.
