About the DS3800HPRB1C1C
The GE Pulse Rate Input Board DS3800HPRB1C1C 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 Pulse Rate Input Board DS3800HPRB1C1C also is populated with 12 jumpers and 1 trimmer resistor. The board also is populated with 1 programmable interrupt controller, multiple programmable interval timer devices, and multiple capacitors.
The trimmer resistor is a valuable component that gives you some ability to adjust the behavior of the GE Pulse Rate Input Board DS3800HPRB1C1C. The board is populated with many resistors that do not have the ability to be adjusted. They are designed to perform a function and no adjustment is called for. However, the trimmer resistor can be adjusted with a small screw located on the component. Only a qualified installer should adjust the trimmer resistor. That is to avoid unwanted results from the adjustment and ensure the proper function of the board.
The installer must have on hand a full-featured testing device. The probes must be in good working order and have no missing or frayed insulation. The probes must also be designed for use with the testing device. With a small flat-blade screwdriver adjust the screw until the desired results are indicated on the tester. In some cases, it is useful to drop a special glue on the screw. The glue hardens and prevents the screw from being turned. The glue peels off cleanly if you need to readjust the screw.
