Waist-High Photo Sweep
A set of Photo Sweep sensors can be mounted at waist height for added safety and peace of mind.
Aisle-Entry Sensor
If a person enters a closing aisle, cross-aisle sensors mounted 20 inches (508 mm) up from the carriage base stop the system from moving.
The Entry/Exit Zone In the
30 inches (762 mm)
of each aisle end, cross-aisle ZFS sensors mounted on 6-inch (152 mm) centers (versus 12-inch [305 mm] centers the rest of the carriage length) ensure safety and automatic reset upon exiting.
Safety Lock Out
Lighted indicators signal when a person or object is in an open aisle, and prevent the selection of a new aisle until the open aisle is checked.
Zero Force Sensor
By projecting multiple infrared photoelectric beams across an open aisle the full length of the carriage, the Zero Force Sensor ®
(ZFS) system detects a
person’s entry into a moving aisle or presence in an open aisle and automatically locks down carriage movement.

An infrared and visible red light beam projected the length of the carriage at its base stops system movement when broken by a person’s foot or other object. An optional mechanical safety sweep is also available.
