11)
Intended areas of use Zone 2, Zone 22
1)
If the protective fields are very wide, there is a possibility that all four alignment quality LEDs will not light
up e
ven when alignment is excellent.
2)
The minimum scanning range specifies a range in which a function is guaranteed to operate correctly
and safely under industrial conditions. A sufficient level of signal reserve to ensure very high availability is
included in the calculation.
3)
The typical scanning range specifies a range in which the safety light curtain operates correctly and safely
under industrial conditions. The level of signal reserve is enough to ensure high availability.
4)
SELV/PELV safety extra-low voltage.
5)
IP*7 is not approved for explosion-hazardous areas.
6)
The external voltage supply must be capable of bridging a brief power failure of 20ms as specified in
IEC60204-1. Suitable power supply units are available as accessories from SICK.
7)
A fuse rated maximum 4A shall be installed in the 24VDC power supply circuit to the device in order to
limit the available current.
8)
The nominal voltage in explosion-hazardous areas is 24VDC.
