Illumination system, operation terminal, and setting method of illumination equipment in illumination system

A method of setting illumination equipment in an illumination system in which a plurality of illumination equipments are connected to a control device via a relay, wherein

• the control device stores in advance information on the relay and a planned connection equipment type which is a type of the illumination equipment planned to be connected to the relay, and
• the method comprises:
• during work to connect the illumination equipment to the relay, searching, with the control device, whether or not the illumination equipment is connected, through the relay;
• when the control device detects that the illumination equipment is connected based on a transmission signal from the illumination equipment, sending, with the control device, an inquiry on a type of the illumination equipment to the illumination equipment and acquiring information on the type of the illumination equipment;
• when the information on the type of the illumination equipment is the same as the planned connection equipment type stored in advance, setting, with the control device, an identification number for the illumination equipment connected to the control device;
• and, when the information on the type of the illumination equipment differs from the planned connection equipment type stored in advance, causing, with the control device, an alert unit connected to the control device to generate a first alert.
