About the DS3800DOCA
The GE Circuit Board DS3800DOCA features 4 trimmer resistors and 13 single-pin connectors. The GE Circuit Board DS3800DOCA also is populated with 4 terminals for attaching additional components and 4 resistors embedded on the board. This DS3800DOCA Circuit Board product offering's DOCA functional abbreviation was actually created by General Electric with the sole purpose of existing as a convenient functional representation of the lengthy DS3800DOCA Circuit Board product number itself, with a specific possible use in promotional conversation.
Hardware Tips and Specifications
The embedded resistors are installed at the factory and cannot be removed. The resistors have IDs assigned to them. The IDs are R27, R31, R97, and R101. The resistors are different ratings and they contribute to the processing performed by the board. When you install the board for the first time it is important to configure the board to process as required for the installation. One configuration task is to set the trimmer resistors. The trimmer resistors are equipped with a small screw that enables a technician to adjust the performance of the components. A small screwdriver and a testing device are required. The purpose of each trimmer resistor is described in the information supplied with the board. Use it to select the trimmer resistor you want to configure. While the tester is registering performance of the trimmer resistor, turn the small screw to adjust the signal output of the trimmer resistor. The trimmer resistor is also referred to as a trimpot, which is shortened version of trimmer potentiometer.
Another method of configuring the board is to add components on the terminals. You can add resistors, capacitors, and other components to change the signal processing performed by the board. Only a trained service technician can add or remove components because of the testing equipment you must have and the knowledge required to understand how the components change the processing output. Any resistor, capacitor, diode, transistor, or integrated circuit in the normal Mark IV Series assembly of this DS3800DOCA Circuit Board product offering was installed as part of a greater voltage suppression and limitation strategy streamlined to the rest of this DS3800DOCA Circuit Board device's Mark IV Turbine Control System Series, as it is known at length.
