I have a BN 3500 panel where a touch screen VGA display shows bar graphs for the vibration points for a steam turbine generator that is currently down. This display frequently blanks out and when it starts coming back on, it displays only a few points with no data. I suspect I have an issue with the TDI card as the TX/RX LED is either out (blank screen) or on solid (partial display with no data) when the display is acting up. Eventually the TX/RX LED starts blinking indicating activity and the display is normal.
Do I just have a failing TDI card or is there a bigger problem? The VGA has an touch screen alarm reset button we have to use in start-up and if it comes and goes we cannot run the machine.
I have started looking for outside support to check out the BN rack cards and display. Any recommendations would be welcomed. I am located in southwest Virginia.
