... X- Status Light (LED) Diagnostics 3M Touch Systems controllers are highly reliable units; however, there may be occasions when the controller does not perform exactly as you expected. The RX142 controller provides diagnostic feedback with a light emitting diode (LED) on the component side of the board that indicates the status of the sensor unit. During normal operation, when you touch the sensor the LED becomes bright as long as the controller detects a touch. A flashing (or blinking) LED during power-up indicates the controller’ ...
