Align t
he MLG-2 such that as many LEDs illuminate as possible.
It may be that they do not all light up; this is normal. Even if not all of the LEDs
lig
ht up, the teach-in process adjusts each beam so that it is located in the opti‐
mum functional range.

All LEDs light up briefly one after another (sequential light). The sensitivity is
stored.

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.
b
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.

On t
he ML
G-2 Prime, the teach-in process can also be triggered via IO-Link or the Teach input.
