1)
If the protective fields are very wide, there is a possibility that all four diagnostic LEDs 1, 2, 3 and 4 will
no
t light up even when alignment is optimal.
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/protective extra-low voltage.
5)
The specified enclosure rating only applies when the system plug is fitted.
6)
In order to achieve enclosure rating IP 66, washers must be used for the fixing screws on the enclosure
cover.
7)
The external voltage supply must jumper a brief power failure of 20 ms as specified in IEC 60204-1. Suit‐
able power supply units are available as accessories from SICK.
8)
A fuse rated maximum 2 A shall be installed in the isolated 24 V DC power supply circuit to the device in
order to limit the available current.
9)
All inputs of the safety light curtain must be supplied by the same voltage supply. If the sender and
receiver are connected to each other, they must be supplied by the same voltage supply.
10)
Within the limits of U
V
