The GE Dom Plus Servo Amp Board DS3800HSAA1K1D features a modular connector on 1 end and retention levers on the other end. The board is populated with a heat sink. The analog/digital converter is a component embedded on the board. The GE Dom Plus Servo Amp Board DS3800HSAA1K1D is also populated with 1 34-pin connector and 1 socket for electrically erasable programmable read-only memory (EEPROM) modules. The board is also populated with 3 trimmer resistors.
The GE Dom Plus Servo Amp Board DS3800HSAA1K1D is 1 of a multitude of boards that can be installed in the drive. Because of the wide combination of boards in the drive and the many purposes for which the drive can be used, the board is equipped with several trimmer resistors. Depending on the other boards in the drive and the application assigned to the drive, the trimmer resistor can be tailored to the task. The adjustment is made by turning a screw on the trimmer resistor with a small screwdriver. Once the adjustment is complete, a hardening agent can be dropped on the resistor that prevents the screw from being turned accidently. The agent can be peeled off if need be.
This might be helpful if the board is installed a new drive with different requirements for the resistor. However, only a qualified technician should make the adjustment. This is to prevent damage to the board. If a poor adjustment is made, the drive will not function at peak performance.
