About the DS3800HPRB1A1A

The GE Pulse Rate Input Board DS3800HPRB1A1A 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 DS3800HPRB1A1A 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 programmable interrupt controller and programmable interval timer devices are not field programmable. They are programmed during board assembly and you can not configure the devices before installation. However, the trimmer resistor can be configured before installation. The trimmer resistor is adjusted by turning a screw accessible on the top of the device. A qualified servicer can adjust the trimmer resistor. The servicer must understand how to use and calibrate the full-function testing device. The servicer must also know how to adjust the board to enhance the drive operations. And, understand the safety considerations of working inside the drive.

One consideration about working in the interior of the drive is the risk of electric shock.  If the components in the drive are touched while current is present, a high-voltage shock can occur. This can lead to injury or electric burns. Make sure all power is removed from the drive before touching the components. Keep in mind that the drive has more than 1 source of electric power. Some are dc power and other are ac power. Use a testing device to test for power after you remove power to verify that no power is present.
