Mounting, installation and commissioning
Only one light curtain can be mounted in the door opening. In this case, the "door function"
of the light curtain prevents detection by the door itself.
When the light curtain is being mounted, it is to be placed on a stable subsurface. Ensure
that the ground is sufficiently level so that the sensor function can work at all points.
The first fixing clamp should be around 10cm above the ground and the last clamp should
be 10cm from the end; between these points, fixing clamps should be used to fasten the
profile at maximum intervals of 60cm. Optical components (transmitters, receivers, LEDs)
must not be covered.
A risk assessment in accordance with the machinery directive is the basis for deciding on
the selected safety method.
The alignment of the light curtain should be optimised after it has been mounted. If the
test input of the light curtain is activated for longer than 15s, the light curtain switches into
alignment mode. The signal reserve can be optimised in alignment mode by alternately
rotating the LIGI transmitter and LIGI receiver.
If the signal reserve is less than 2, the green receiver LED flashes in this mode. The green
LED remains on for signal reserves greater than 2 and the red receiver LED flashes with
increasing flash frequency when the signal reserve increases. The signal reserve should be
a factor of 2 or greater to ensure fault-free operation as well as to tolerate a certain amount
of dirt.
As soon as the test input is deactivated for a short period, the light curtain returns to normal
mode.
After installation and fine adjustment the light curtain should be switched off and back on
again before the performance test. The transmitter is than self adjusting the optinum power.
