SICK deTec4 C4P-EA 3SC05 Series - Status Indication

If the configuration was changed, the diagnostic LEDs flash white for 3s upon activa‐
t
ion.
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.
11.3.2 Status indication
Overview
Dur
ing operation, the status of the safety light curtain is indicated with LEDs.
Sender
P
osition of the LEDs: see "Sender displays", page 17.
If the sender and receiver are connected to each other by a cable, the LEDs on the
sender indicate the same status as the LEDs on the receiver during normal operation.
The STATE LED on the sender adopts the status of the OSSD LED on the receiver.
If the sender and receiver are not connected with each other, the STATE LED on the
sender lights up yellow when the sender is in operation and no faults are present.
Receiver
P
osition of the LEDs: see "Receiver displays", page 18.
