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 RX182 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’s power-on self-test
failed. Refer to the following table for a description of each error code.
