Non-SICK Power supply unit/connections without the Connection Module
Power output
If an non-Sick Power supply unit is used instead of the AMS 60, it must be capable of
providing the following voltage and power values:
•
For CLV without heater: 18 ... 30 V DC, min. 20 W continuous power output
•
For CLV with heater: 24 V DC +20 %/–10 %, min. 100 W
The non-Sick Power supply unit must comply with IEC 742 (functional extra-low voltage).
The output circuit must be reliably electrically isolated from the input circuit pursuant
to IEC 742 by means of double insulation and a safety isolating transformer.
Wire cross-section
The wire cross-section for the power supply (Pin 1/Pin 5) should be at least 0.15 mm
2
, or
0.75 mm
2
for CLVs with heater, with a max. length of 10 m.
a) Connecting the CLV without a connector cover/external parameter memory
The two cables no. 2 020 303 and no. 2 020 264 with open cable end on one side are
required to connect the CLV. The wire color assignments are shown in
and
.
The cables must not be extended for CLVs with heater.
