Abstract
A display monitor is provided for a multi-optical-path photoelectric safety apparatus including a plurality of multi-optical-path photoelectric sensor units. The user can determine whether a special function such as blanking is set for each optical path in a group which comprises a plurality of indicator lamps placed in a row along a longitudinal direction. The user can check the light incidence/light block status for each optical path on an indicator lamp group. The display monitor includes the plurality of indicator lamps placed in a row in the longitudinal direction. First and second switches allow the user to select the unit and the optical path to be shown on the two indicator lamp groups.
