About the IC3600STFA1
The IC3600STFA1 is a printed circuit board (PCB) made for the Mark I-II turbine control series. The Mark I and Mark II were the earliest series created in the Mark line by General Electric (GE). The IC3600STFA1 is an overspeed test circuit board.
Overspeed events can cause dangerous and costly failures in turbines. Overspeed tests are conducted at times to make sure that the system has the correct response time to protect the turbine equipment and operators. Routine overspeed testing is the only way to make sure that the turbine’s protection system is working properly.
The IC3600STFA1 features two large switches on the left side of the board. These switches are fixed onto a metal plate which is lined up along the side of the PCB. These switches are positioned near the center of the plate. The switch on the top is black and it is labeled SW1. This switch is attached to the board with white wires to seven numbered holes in the PCB’s surface. Below this component, there is a second switch. This switch is red and it is labeled as SW2. Three (3) wires which are labeled A, B, and C connect this switch to the IC3600STFA1. One metal part is attached to the board with a long green wire. This part is labeled as GN0. A long line of nearly fifty (50) metal prongs can be found along the right edge of the IC3600STFA1. These parts are labeled as five (5) through fifty (50). IC3600STFA1, the full part number of the printed circuit board, is printed at the top of the board.
