Product Description

The General Electric Emergency Overspeed Board with EPROM modules DS215TCEAG1BZZ01A features one microprocessor and multiple erasable programmable read only memory (EPROM) modules. It also contains 3 fuses, 30 jumpers, and a pair of bayonet connectors. The GE Emergency Overspeed Board with EPROM modules DS215TCEAG1BZZ01A comes with EPROM modules installed on the board. The EPROM modules have the firmware and programming instructions stored on them that the microprocessor uses for normal processing. Installation of this board might be appropriate if the original board contains EPROM modules that are damaged. Before you install the board there are some considerations to keep in mind concerning handling the EPROMs. Wear a wrist strap when you handle the board to prevent static build up. Static can damage the information stored on the EPROM which would prevent the microprocessor from functioning.

The wrist strap provides a means for the static to exit your person or the board by giving a grounded metal surface that the static electricity seeks out. One end of the strap is connected to your arm or wrist and the other end is a clip device that attaches to a metal chair or desk support. Some straps contain a plug that attaches to a connector on a metal surface or a work table. Either way, the static on your person and the board are kept from building up and damaging the EPROM.

The firmware and programming instructions on the replacement EPROMs might be a newer version of the instructions on the defective board.
