A light curtain (108) controller (402) is provided that serially tunes or optimizes the operating margin of each channel during an initialization sequence. The controller (402) measures and adjusts the operating margin for each emitter-receiver (110-112) pair individually, such that the margin for each channel satisfies a defined optimization criterion. In this way, the light curtain's (108) unique environmental and installation conditions are taken into account when tuning each channel. By individually tuning each emitter-receiver (110-112) pair, the operating margin of each channel is set sufficiently high to ensure accurate object detection, while excessive margin is limited to prevent signal processing errors, such as those associated with adjacent-channel signal bleed-through, susceptibility to internal and external noise, etc. |
