PURPOSE:To save electric power of an illuminator for a factory by connecting abnormal signal generating means of machine belonging to respective zones through switching means with a timer to district illuminator lamps to thereby energize the lamp at abnormal signal generating time of the corresponding district and deenergizing it after this signal is disconnected. CONSTITUTION:When a weft detector 6 of certain zone detects no weft W at electrodes 7, 7' thereof at weft detecting timing in a loom in a factory, it generates a stop signal. Accordingly, a loom stopping circuit 14 is operated to close a contact 9 to energize an illuminator lamp 5a. When the loom is repaired with weft and is restarted, the detector 6 is reset to stop generating stop signal. However, since a timer 8 continues its operation, the illuminator lamp 5a remains energized. Accordingly, after the loom is restarted, the loom can be confirmed in the repaired state. Even if a worker separates from the loom as it is, the lamp 5a is automatically deenergized. This illuminator is adapted for a factory arranged with a machine for taking substantially the same repairing time as looms. |
