The GE General Regulator Board DS3800DMPK1B1B features 14 erasable programmable read-only memory (EPROM) modules. The GE General Regulator Board DS3800DMPK1B1B also is populated with 2 34-pin ribbon cables, 2 single-pin connectors, and 17 jumpers.
The EPROM modules store the firmware and other software instructions that the microprocessors and other components use to control the drive. Once the drive is operating satisfactorily, it is common to the keep the firmware and software stable and not upgrade to a newer version. If that is the case, it is easy to replace the board if it is defective. The EPROM modules can be removed from the defective board and installed on the replacement board. All that is required to have on hand is a flat-blade screwdriver.
The replacement board comes in a sealed static protective bag. It is best practice to keep the bag sealed and in the shipping box until you need it. Wear a wrist strap and slice open the end of the bag to open it. It is best practice to slice it open so that the bag can be reused. Remove the board from the bag with 2 hands and hold the board by the edges only. Never hold the board with one hand so that the components are bent, damaged, or torn off the board. This can easily happen if you put pressure on the components while you hold the board with your fingers on the components.
Place the board on top of static sensitive bag and place the old board next to it. The replacement board comes without EPROMs and it is a quick procedure to move the modules from the old board to the replacement.
