Figure 26: Mounting the SafeShield safety light curtain with side bracket
Note
➢ When mounting the side bracket make sure that the
bolts marked
➋ and ➧ remain accessible, allowing you
later to adjust and lock the light curtain in position.
➢ If you wish to use the additional front screen (see page
45), make sure that the curved side of the device
remains accessible after mounting.
Electrical Installation
Connect OSSD1 and OSSD2 separately!
To ensure that the signals are safe, OSSD1 and OSSD2 are to be
connected separately to the machine controller and the machine
controller must process the two signals separately. OSSD1 and
OSSD2 must not be connected together.
ATTENTION: Switch the entire
machine/system off line!
The machine/system could inadvertently
start up while you are connecting the unit.
➢
Make sure that the entire machine/
system is disconnected during the
electrical installation.
Notes
• The two outputs are protected against short-circuits to
24V DC and 0V. When the light path is clear, the signal
level on the outputs is HIGH DC (at potential), when
the light beams are interrupted or there is a device fault
the outputs are LOW DC.
• The SafeShield safety light curtain meets the
interference suppression requirements (EMC) for
industrial use (interference suppression class A). When
used in residential areas it can cause interference.
• To ensure full electromagnetic compatibility (EMC),
functional earthing (FE) must be connected.
• The external voltage supply of the device must be
capable of buffering brief mains voltage failures of 20 ms
as specified in EN 60204-1.
• System connections and extension connections in a
cascaded system must be connected only if the system is
off line. The configuration connection however, may be
connected/disconnected with the system on line.
