When commissioning an L or T-type or external muting sensors, this alignment must also
be carried out, followed by alignment of the muting sensors.
INFORMATION
For simple, precise alignment of the safety light grid and muting sensors we
recommend the use of the laser pointer (order no. 630 340).
Particularly where there are:
- difficult environmental conditions
- large distances between the safety light grid's receiver and transmitter
7.2.2
Safety light grid alignment
Prerequisites
}
Transmitter and receiver are inserted correctly in a suitable place
}
Wiring has been carried out correctly
}
Supply voltage is switched off
}
Protected field is clear
Procedure
1. Press the TEST/START button and keep the button pressed down.
2. Switch on the supply voltage to the safety light grid.
3. Release the TEST/START button.
4. Prevent anyone from accessing the protected field during the whole time that alignment
takes place.
5. Check that the lower, green LED and the yellow LED on the transmitter are lit. The
transmitter is ready for operation and is working correctly.
6. Start the alignment if the red LED is lit (incorrect alignment). If the green LED and both
yellow LEDs are lit, the alignment is already correct.
– Hold the receiver steady and align the transmitter so that the lower yellow LED is lit.
This means that the lower beam is aligned.
– Rotate the transmitter around the light axis of the lower lens until the upper yellow
LED is also lit, the red LED goes out and the green LED lights.
– Check that the green LED is permanently lit.
7. Tighten up all the fixing screws.
8. Switch the supply voltage to the safety light grid
off and then on again.
9. Check that the green LED on the receiver is lit.
10. Check that the safety light grid operates correctly.
If a single light beam is interrupted by an opaque object
– the green LED must go out,
– the red LED must light and
– the safety light grid
must switch to a safe condition.
