The GE Microprocessor Board DS3800HMPK1D1B is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE Microprocessor Board DS3800HMPK1D1B also is populated with 3 red indicator LEDs and 1 amber LED which are visible from the front of the board. The board also is populated with a microprocessor, erasable programmable read-only memory (EPROM) modules, and a 34-pin connector. It also is populated with 2 50-pin connectors.
The GE Microprocessor Board DS3800HMPK1D1B also is populated with a reset button. This can be useful if the amber LED is lit. The amber LED indicates that a warning has been issued. The warning might mean that the command signals have become garbled or exposed to interference and board processing is out of sequence. If that is the case, the reset button can allow signals and processing to restart which might enable all board functions to return to a healthy state.
However, the reset button is for use by a qualified servicer only. Only a qualified technician is trained to work inside the drive while power is on. The board and other components in the drive are powered by high-voltage current and can cause serious electric shock and burn if touched while powered on. Additionally, the moving parts in the drive, including the motor, can cause harm to individuals.
When the reset button is pressed, power remains in the board but processing is halted for several seconds. Then, processing is reset. This can clear some processing and signal problems.
