Safety light curtains are most simply described as photoelectric presence
sensors specifically designed to protect plant personnel from injuries related
to hazardous machine motion. Also known as AOPDs (Active Opto-electronic
Protective Devices), light curtains offer optimal safety, yet they allow for
greater productivity and are the more ergonomically sound solution when compared
to mechanical guards. They are ideally suited for applications where personnel
need frequent and easy access to a point of operation hazard.
Application areas include perimeter guarding for industrial robots and
machinery, and point of access guarding for automated machine assemblies. A
photoelectric transmitter projects an array of synchronized, parallel infrared
light beams to a receiver unit. When an opaque object interrupts one or more
beams, the light curtain controller sends a stop signal to the guarded machine.
The transmitter unit contains light emitting diodes (LEDs) that emit pulses of
invisible infrared light when energized by the light curtains timing and logic
circuitry. Light pulses are both sequenced (one LED after another) and modulated
(pulsed at a specific frequency). The receiver unit contains phototransistors
and supporting circuitry to detect only the specific pulse and the frequency
designated for it.
Using mirrors reduces the operating range up to 25% per mirror. (Example: 6
inches to18 feet.) Protection height is the dimension of the active sensing
field (correlates to the number of beams required). Sensitivity or resolution is
the smallest sized object that will be positively detected by the light curtain.
The response time of the light curtain is the maximum time between actuation of
sensing function and the output relays. Operating temperature is the
full-required range of ambient operating temperature.
Most light curtains require an external controller. They may either come equipped with an integral controller, in which case they will not require the external controller, or they come equipped with the external controller. Multi-tasking controllers that monitor and control more than one set of light curtains are also available. Light curtains may be mounted on brackets, DIN rails, or the floor.
