Status Light (LED) Diagnostics
3M™ MicroTouch™ controllers are highly reliable units; however, there may be
occasions when the controller does not perform exactly as you expected. The RX181
controller provides diagnostic feedback with a light emitting diode (LED) on the
component side of the board that indicates the status of the sensor. 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 Table 2 for a description of each error code.
