About the DS3820P1MB
The DS3820P1MB is an HMI interface created for the Mark IV series. The MKIV is designed for steam or gas turbine management. It replaced GE’s earlier Speedtronic series, like the MKI and MKII with a more efficient, more reliable system using microprocessors and a more flexible user interface.
The DS3820P1MB is the control panel for the Mark IV system. It fits around a computer display. The DS3820P1MB is painted matte black and connects to the frame using eight screw connections located around the edge of the panel. The panel has a large cut-out in its upper left quadrant to allow for a computer display. The panel is labeled above this cut-out “Speedtronic Gas Turbine Control System.”
The DS3820P1MB has ten distinct areas on its front area. They are as follows:
-
Emergency Stop Button. Located in the bottom right of the panel, the emergency stop button is large and red.
