Use of Existing Attachments With New Regulator
Some attachments used with the former regulator must be replaced if the new regulator is installed. Other attachments can be reused.
... Remote Voltage Level. This potentiometer is mounted in the control panel or the switch gear, and must be replaced with a 7C4471 Potentiometer. Wiring connections are included in the Special Instruction and in the Service Manual Supplement.... Voltage Droop Control. The 6L7007 Droop Potentiometer can be reused by removing it from the former regulator and installing it in the opening in the new mounting bracket. Wiring connections are provided in the Special Instruction and in the Service Manual Supplement.... Series Boost. A new series boost module and associated parts will be available later for the new regulator. The existing series boost is electrically compatible with the VR3. Provisions for mounting the existing series boost with the VR3 are not provided.... Manual Control. A new 7C2700 Manual Control Assembly is available for use with the new regulator. The 5N1613 Manual Control used with the A1-type regulator cannot be used with the new regulator. But, the 5N591 Manual Control Assembly used with either the 5N9440, 5N9441 or 5N9442 Regulator Assembly can be used with the new regulator. Contact your Service Engineering Product Analyst for installation instructions if the 5N591 Manual Control Assembly is to be reused.
