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.
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.
