Commissioning
Teach-in sensitivity
During commissioning and at regular intervals, as necessary, the
optimum sensitivity must be taught in for each receiving beam path
on the light grid. This procedure is called teach-in.
1. No objects should be between the sender and the receiver. The
light path must be clear.
2. Switch on the power supply for the light grid. The green LEDs on
the receiver and the sender should illuminate.
3. Depending on the type of light grid:
MLG PROFIBUS DP and MLG CANopen: Activate and deacti-
vate teach-in mode via the interface.
MLG programmable: Use the configuration program
MLGsetup to teach-in.
MLG/XLG with input: Activate teach-in via input “In1 (Teach-
in)”. Deactivate the signal after 20 ms.
Other MLGs/XLGs: Teach-in starts automatically after the
supply voltage is switched on.
During teach-in, “L” will be displayed on the 7-segment display on
the receiver.
4. The yellow LED on the receiver illuminates. The light grid is opera-
tional.
