Installation of Light Curtains
The light curtains must be installed at the entrance of the fencing, away from the wrap zone and be
positioned as close to the fencing as possible (refer to overview drawing). Make sure the posts are
leveled (both sides, vertically) before anchoring. Maximum distance is 14’, but the closer from each
other they are the easier it will be to adjust them.
1.
Anchor the posts.
2.
Make sure both light curtains are at the same level/height.
3.
Connect the light curtain, if not connected already.
4.
Final alignment is performed by mechanically adjusting the light curtains components, using the
top light beams as guide.
5.
The alignment mode is automatically activated when the light curtain is switched on if the light
beams are not yet aligned or the light path is interrupted.
Top light beams (A)
•
Red light beam – light curtain is misaligned or an obstacle is blocking
the path
•
Green light beam – system clear
•
Yellow light beam – muting in action, will never occur with this setup
Bottom light beams (B)
•
Red light beam – light curtain is misaligned or an obstacle is blocking
the path
•
Orange light beam – cleaning or alignment required
•
Yellow light beam – reset required
•
Green light beam – system clear
6.
The light curtains will reset themselves each time the light is broken but a rearm must be
done on the lanyard or the control panel to enable the wrapper to begin a cycle.
