In addition to a floor-level safety sweep, your system may be
equipped with one or more of the following safety options:
Waist-High Photo Sweep
An additional set of Photo
Sweep sensors can be mounted
at waist level for additional
safety. This is typically mounted
at reference shelf height. For
this safety, shelving elevations
need to be consistent, and
overhanging media should not
be present as it could block the
beam. This DOES NOT replace the floor-level sweep.
Hinged Door Protection Photo Sweep
Another Photo Sweep can be added to detect if a hinged
door is open. Again, this DOES NOT replace the floor-level
sweep.
Aisle-Entry Sensor
This feature has an invisible
beam that crosses each aisle.
The following actions occur
when using this safety feature:
• Entering an open aisle
will break the beam, and
prevent the system from
moving.
• Entering an opening aisle will have no effect on the
opening of the aisle, but will prevent the system from
moving once the aisle is fully opened, until the system
is reset.
• Entering a closing aisle breaks the beam stopping
system movement.
In all of the above situations, when you leave the aisle, you
will have to press the “Stop/Reset” button at that aisle in
order to return the system to normal operation.
Zero Force Sensor
®
System
This safety feature requires no
effort on your part. As you
enter the aisle, you are
detected by invisible light
beams. As long as you remain
in the aisle, no carriage
movement is possible, and the
“aisle in use” message is
displayed on the control along
with a solid red light.
As you leave the aisle, the system will automatically return
to a “green light” condition, meaning that it is ready for
use. If it does not go to “green”, please check the aisle for
any obstruction and then press the reset button for normal
operation.
