Chapter 1 Integrating the MT410 Controller 19
If it was necessary for you to mount the controller component side down,
you can determine the status of the LED from its reflected light off the
mounting surface.
Status Light (LED) Diagnostics
MicroTouch controllers are highly reliable units, however there may be
occasions when the controller does not perform exactly as you expect. The
MT410 controller provides diagnostic feedback with the LED shown in
Figure 7.
When you power-up the unit, the LED is on until the controller start-up
sequence is completed. Following start-up, the LED goes out and remains
out as long as you do not touch the sensor. When you touch the sensor, the
LED goes on.
A flashing (or blinking) LED during power-up indicates the controller’s
power-on self-test failed. Refer to Table 3 for a description of each error
code.
