About the DS3800HAIA1E1D

The GE Analog Conversion Board DS3800HAIA1E1D is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE Analog Conversion Board DS3800HAIA1E1D also is populated with 2 34-pin connectors between the retention levers. The board is populated with 2 trimmer resistors and 8 jumpers. The board is also populated with 1 socket for an electrically erasable programmable read-only memory (EEPROM) module.

The trimmer resistors each is assigned an ID. The IDs are printed on the board and they describe the purpose of each trimpot. Gain and Offset are the IDs of the trimmer resistors. The trimmer resistors are also called trimpots. This is because the trimmer resistors are also potentiometers. Potentiometers are adjustable resistors. The trimpots are adjusted using a small screw. The screw is accessible from the surface of the component. Best practice is to remove the board from the drive before adjustment. Also, the servicer will use a testing device to monitor the circuit and at the same time turn the screw of the trimpot. When the target resistance is obtained, you can drop a substance over the screw to prevent further adjustment. The liquid hardens. If the board is remove from the drive and installed in another drive, the substance can be peeled off so that the trimpots can be adjusted again.  

The ribbon cables are connected to the 34-pin connectors on the front of the board. Refrain from tugging the ribbon cable to remove the connector. This can damage the ribbon cable and disconnect the signal wires from the connector.
