The GE Protective Termination Expander Board DS200TCEBG1 features 3 bayonet connectors, 4 signal transformers, and 1 26-pin connector. It also contains 4 10-pin connectors and 3 20-pin connectors. The 3 bayonet connectors are labeled JWX, JWY, and JWZ on the board. Cables with male bayonet connectors are designed to connect to them and there are some guidelines to consider. To connect a bayonet connector to the board, align it with the connector on the board and press it into place. When it is firmly connected, it clicks into place. To disconnect a cable with a bayonet connector, grasp the connector with your thumb and one finger. With the other hand support the board and keep it from moving. Pull out the cable and move it out of the way of the board.
Notice how the cable is routed in the interior of the drive and maintain the cable routing. Cable routing is important because it reduces interference in the signal cables and maintains the free flow of air. Interference occurs when power cables, which produce interference, run too close to signal cables. If signals are not being transmitted or received accurately, the drive will not operate effectively. Air flow cools the components of the drive and increases the length of time between when the components must be replaced.
The 4 10-pin connectors are labelled JPU, JPV, JPW, and JMP. When the board is replaced, take time to inspect the defective board before you remove it. Create tags from masking tape or other means and write down the connector ID to which the cable is connected and tape the ID to the cable.
