Abstract
A component for light curtain alignment includes a light intensity receiver that receives a plurality of light intensity signals from beam receivers of a receiver unit of a light curtain. The light curtain includes a transmitter unit with beam transmitters arranged linearly on the transmitter unit. The light curtain includes the receiver unit with the plurality of beam receivers arranged linearly. Each beam receiver is configured to receive light from a corresponding beam transmitter. The component includes a light intensity transmitter configured to transmit, from the light curtain, the plurality of light intensity signals received by the light intensity receiver, where each light intensity signal is from one or more beam receivers, and a trip transmitter that transmits a trip signal in response to determining that a light intensity signal from a beam receiver of the plurality of beam receivers is below a trip threshold.
