About the 0-56921-606
The 0-56921-606 is a Reliance Electric Regulator PCB that was created for the GV3000/SE series of controllers. This board may have also been sold and produced by ABB and/or Baldor Reliance.
The 0-56921-606 is a replacement card for a regulator board on a GV3000/SE controller. This card is the sixth version of this card that was created by Reliance. This board is compatible with many different types of controllers. These controllers range from 1-200HP and 230/460 VAC.
When installing the new 0-56921-606 into a controller, make sure you take note of the jumper and terminal wire positions so that you can install the new board using the same setup. You will also need to save all of the hardware that is removed from the original board to help you to remount the new board.
The 0-56921-606 is attached to the keypad on the controller using a mounting bracket. It is then connected to the Power Module Interface Board using a 34-pin ribbon cable connector. This board is also plugged into the controller using a 26-pin green-striped ribbon cable that is located on its right. Some of the more important features on this board include microprocessors, the 7-segment LED keypad user display, the J17 and J4 jumper connections, a user I/O terminal strip, and an RS-232 connector.
The 0-56921-606 uses Instruction Manual D2-3369 to detail the specific installation instructions for the version 6 regulator boards. When installing this regulator, it is recommended that you remove the drive from its panel (if its panel mounted) because it will be much easier to install the 0-56921-606 if the drive is not mounted to the panel.
