TRACK GP 3114386 - Caterpillar

The CDVR has three multipin plug connectors. The connectors have the following markings: "P6", "P9" and "P12". Connector "P6" mates with a corresponding connector with six pins on the harness. Connector "P9" mates with a corresponding connector with nine pins on the harness. Connector "P12" mates with a corresponding connector with 12 pins on the harness. Refer to the Tables 1, 2 or 3. Each table corresponds to the connector number in order to identify the function of each pin in the connector.

Illustration of a typical CDVR installationThe CDVR does not require a burden resistor. When changing from a DVR, remove the resistor in parallel with the CT for sensing droop. The CT connections are polarized. One of the terminals has a dot. Confirm that the CT connection with the dot is connected to P12-1 on the CDVR. Refer to the Illustrations 2, 3, and 4.Note: Whereas the DVR and CDVR require 24V DC power, the VR6 does not. When converting from the VR6, two extra wires will be needed to jumper from the existing battery power terminations to the included terminal block. Refer to the Table 4 for the recommended DC wiring.Note: If the CDVR harness wires (1A and 2A) are long enough for the installation, the recommended battery jumper wires will not be necessary.

Illustration of a terminal block with connections for thermocouplesDifferent labels and additional terminals are provided in the parts kit. These parts are required for the terminal blocks. These terminal blocks may be located inside the generator terminal box or located in a remote location. Some labels may need to be changed on the terminal blocks or added to the terminal blocks. These labels include the following: "VAR/PF", "Enable", "Fault Reset" and "Excitation Disable". Refer to the Illustrations 4 and 5. Install the new terminals and labels that are required for your specific application. Refer to the Illustrations 6 or 7.A new momentary switch is provided in the parts kit. The part number for the switch is 110-7884 Toggle Switch . This switch is used to adjust the voltage on the CDVR output. The common wire to the switch will replace the following connections: pin 50 to "Excitation Disable", "Fault Reset" and pin 52a enable for VAR and PF. This switch also replaces the rheostat that was used on the DVR and VR6. Refer to the Illustration 5. CAN datalink communication wires (P9-1, 2 and 3) are not included in the 243-4271 Wiring Harness . If datalink communication for the CDVR is desired, it will be necessary to install the additional 153-2707 Electrical Cable . Three 244-0452 Wire Ends will also be needed. These parts are included in Table 4, "Additional Parts Required for the VR6".Note: When installing the CDVR on the J1939 datalink, please be aware of the terminating
