SICK deTec4 C4P-EA 3SC05 Series - Check During Commissioning and Modifications

Indication of the alignment quality
Position of LEDs: see "R
eceiver displays", page 18.
If front screen contamination increases in ongoing operation, the laser alignment aid
switches on or the alignment takes longer than 3seconds, the receiver shows the
alignment quality again.
Once the safety light curtain is aligned and the protective field is clear (field indicator:
flashing yellow or lit up green), the alignment quality display switches off after a certain
period of time.

If external device monitoring is configured and there is an EDM warning, diagnostic LED 1 flashes, while
the other diagnostic LEDs 2, 3 and 4 indicate the alignment quality. If there is an error on the reset
pushbutton, diagnostic LED 4 flashes, while the other diagnostic LEDs 1, 2 and 3 indicate the alignment
quality.
2)
If the protective fields are very wide, there is a possibility that diagnostic LED 4 does not light up, even
with optimal alignment.

8.4 Check during commissioning and modifications
The thorough check is intended to ensure that the safety functions are fulfilling their
planned pur
pose and whether persons are being adequately protected.
