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
MT3000 controller provides diagnostic feedback with an LED as shown in
Figure 6.
Figure 6 Diagnostic LED (component side)
When you power-up the unit, the LED is bright until the controller start-up
sequence is completed. Following start-up, the LED becomes dim and
remains dim as long as you do not touch the sensor. When you touch the
sensor, the LED becomes bright.
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.
