ReferenceSpecial Instruction, REHS4494, "Installation Instructions for the New Caterpillar Digital Voltage Regulator (CDVR) In Field Retrofit Applications"Generators that are operating in harsh applications involving very low-power factor loads (for example, rock crushing) may experience high excitation currents.For these harsh applications, an optional upgrade to a Caterpillar Digital Voltage Regulator (CDVR) is now available. The option of using the CDVR allows higher output capability than the VR6.Refer to the service media listed above for further details in making this optional upgrade.
