Align t

It may be that they do not all light up; this is normal. Even if not all of the LEDs

The yellow LED on the front flashes slowly.
If the teach-in process is successful, all LEDs on the control panel go out, as does the
yellow LED on the front of the device. The MLG-2 is operational.
If the teach-in process was unsuccessful, all LEDs on the control panel flash quickly, as
does the red LED on the front of the device.

Then, check that the MLG-2 is correctly aligned, that the front screens are clean
and that there are no objects located in the light path.

Then carry out the teach-in process again.
