The GE Mark IV Printed Circuit Board DS3800HADA1B1B features multiple pins that are connected through fine wires wrapped around the pins. The GE Mark IV Printed Circuit Board DS3800HADA1B1B also is populated with 8 jumpers for configuring the board and 1 decoder/demultiplexer component.
Some of the multiple pins on the board are attached to each other with fine wires. The fine wires route signals between the pins to obtain a specific processing result. However, when you install the board for use in the drive, a technician or installer can add, remove, and change the position of the wires. Only a qualified individual should attempt to move the wires. This is to assure that the results are appropriate for the site and what the engineers and operators intended. If rework is needed, it will result in more downtime for the drive and added installation expense.
The wires should only be moved when power is removed from the board and the board is placed on a static-protective surface. The details about the pins and how connecting specific pins together can change signal routing are provided by the factory in the hard-copy installation instruction included in the shipping carton. The drive operators and engineers and other knowledgeable individuals at the site should direct the technician in how best to change the wiring of the pins.
Further configuration can be made to the board by using the 8 jumpers that populate the board. The decoder/demultiplexer cannot be configured. It combines signals before they are transmitted to other boards in the drive.
