Abstract
A method of installing a multi-beam photoelectric safeguard system for making a light curtain of closely aligned light beams closely to a pressing machine first positions main light emitting and detecting devices (11, 12). The method next mounts a projecting portion (21) to the pressing machine and identifies optical axes interrupted by the projecting portion (21). Subsequently, after setting a sub light detecting device (13) adjacent to one side of the projecting portion (21), the method adjusts optical axes between the sub light detecting device (13) and the main light emitting device (11). Finally, after setting a sub light emitting device (14) adjacent to the other side of the projecting portion (21), the methods adjusts optical axes between the sub light emitting device (14) and the main light detecting device (12).
