Intended areas of use Zone 2, Zone 22
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 extra-low voltage.
5)
The specified enclosure rating only applies if the system plug is fitted and the protective cover for the DIP
switches, which is attached to the SP2 system plug, is securely closed.
6)
IP*7 is not approved for explosion-hazardous areas.
7)
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.
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)
The nominal voltage in explosion-hazardous areas is 24 V DC.
11)
Within the limits of U
V
.
12)
For more detailed information on the exact configuration of your machine, please contact your relevant
SIC
K subsidiary.
13)
The values apply for an installation height of up to 2,000 m above sea level. Additional information can
be found at your SICK subsidiary.
14)
The maximum permissible current must be observed.
15)
Calculation of number of beams:
•
Resolution 14 mm: protective field height/mm / 10 (example, protective field height 2,100 mm:
2,100/10 = 210 beams)
•
Resolution 30 mm: protective field height/mm / 25 (example, protective field height 2,100 mm:
2,100/25 = 84 beams)
16)
Direction of movement and axis of the test rod perpendicular to the protective field.
17)
The values apply for the time from when the ESPE becomes clear until the termination of muting and
contain a sensor gap monitoring ESPE and a muting end delay.
18)
The symbol “X” refers to the following points: reduced impact resistance of transparent parts, avoidance
of static charge, avoidance of UV radiation, temperature range.
