Description

The GE Excitation Power Board DS3800DEPB features 1 20-pin ribbon cable and 5 10-pin connectors. The GE LCI Exciter Control Board DS3800DEPB also is populated with 4 terminals for adding components, and 2 trimmer resistors.

You can add a maximum of 2 additional components with use of the 4 terminals that populate the board. In some situations additional components are necessary to configure the board to process information as required for the drive. By adding components to the terminals, it becomes a simple and fast solution. For example, if adding a capacitor is necessary, you can loosen the screws on 2 of the terminals associated with the circuit and add the capacitor. There are some factors to consider when adding components. Only a qualified installer or servicer should add components to avoid damage or unintended results. The use of a calibrated tester is necessary to understand how the additional component will change the processing results. Another consideration is that the additional components are subject to damage due to the height of the terminals. You might scrap against an object in the drive and break off the component.

When the 5 10-pin ribbon cables are connected to the board, the cables must be routed to avoid problems. One consideration is that the five cables can restrict the free flow of air in the drive. The cool air enters the drive at the bottom and flows upward to cool components and carry away the heated air. If the air is blocked, the interior of the drive might become hot enough to damage components.
