3. Turn on each laser by placing a finger or hand in front of each laser
(close to the finger symbol
4. For optimal alignment, adjust the transmitter and receiver in such a
way that both visible laser beams hit the laser targets opposite each
laser. A small deviation around the target is allowable and are harmless
as long as they are within the aperture angle.
5. Tighten all screws firmly.
6. Switch the ILAS off when aligned.
When mounting Perimeter Systems adjust the heights according to the
recommendations in the local standards and regulations (Europe: EN
ISO 13855 [2010]) (see Figure 2).
The GuardShield Safe 2 safety light curtain is suitable for most operating
environments (IP65 environmental rating). Proper safety distance as well
as adequate protective height must be observed.
Remarks to ILAS
Due to dimensional tolerances the visible ILAS laser beam may be
located "off center" from the target when the light curtain is aligned
optimally in the center of the operating range. The optimal operating
point can be found after alignment with ILAS when moving the axis in
X- (left, right) and Z- (up, down) direction. The optimal operating point
is in the middle of the two end points, where the receiver output switches
from active to inactive condition.
On optimal alignment of the light
curtain, the ILAS light point can deflect
from the ILAS target point. The
maximum deflection adds up to the
following value due to the operating
distance:

D = 7 mm

R = 20 mm

Correct Installation
Operators cannot reach hazardous
machine parts without passing through
the protective field.
Operators must not step between
protective field and hazardous machine
parts (by-pass prevention).
Incorrect Installation
Operators can reach hazardous machine
parts without passing through the
protective field.
Operators can step between protective
field and hazardous machine parts.
The GuardShield Safe 2 must be mounted at the proper distance from
the point of operation hazard. This distance is referred to as the Safety
Distance.
