Product Description
The GE Emergency Overspeed Board DS200TCEAG1A features one microprocessor and multiple programmable read only memory (PROM) modules. It also contains 3 fuses, 30 jumpers, and 2 bayonet connectors. The PROM modules store the firmware and operating instructions used by the microprocessor. When you replace the GE Emergency Overspeed Board DS200TCEAG1A you will note that the replacement board is not populated with PROM modules. The replacement board is populated with the PROM sockets but the PROM modules are not installed. Since the PROM modules are easily removed and installed, you will find it is a simple task to move the modules. One advantage of using the same modules is that when you restart the drive, the new board will operate with the same set of instructions and firmware.
However, when you handle the modules there are some guidelines and instructions you must consider. Static can damage the information stored on the PROM modules and thereby make the information unusable by the microprocessor. To avoid that situation, you must take steps to remove the static from your person and the modules. The easiest way to do that is to obtain and wear a wrist strap when you work on the board or handle the PROM modules. In order for the wrist strap to function, both ends of the wrist strap must be properly connected. One end is wrapped around your wrist or forearm. The other end of the wrist strap contains a clip that you attach to a metal surface, for example a metal stool or chair leg.
