Abstract

PURPOSE:To simplify the lamp check work and to eliminate a check circuit by extinguishing a ready lamp at the time of the occurrence of abnormality in a computer system. CONSTITUTION:When an error indication flag provided in the computer system is turned off, contacts rl1-rl4 are closed to light ready lamps L1-L4; and if the error indication flag is turned on because of the occurrence of some abnormality, contracts rl1-rl4 are opened to extinguish ready lamps L1-L4. When they are lit, normalcy of indicators is checked; and when they are extinguished, abnormality of indicators or a lighting circuit is checked if there are no other events indicating abnormality. Thus, the lamp check work is omitted and lamp check switches or the like are eliminated to simplify a device.
