Abstract

PURPOSE:To detect the abnormality of separate interlock and the abnormality of a display lamp, by connecting the contacts of change-over switches in parallel with each interlock contact while connecting the lamp to the series circuit. CONSTITUTION:The contacts X1-X6 of relays corresponding to drive conditions form a series circuit, and the change-over switches, etc. of the change-over switches 3, 4 of contacts 1, 2 are separately connected in parallel with these contacts X1-X6 in corresponding shapes. A relay X is connected through a switch of contacts 15, 16 and a lamp L through a switch of contacts 13, 14. Consequently, the interlock of the X1 is confirmed by opening only the switch of the contacts 1, 2 and the switch of 15, 16 when a change-over location is B, and the same rule applies correspondingly the following while the abnormality of the lamp can be affirmed by a change-over location A, thus accurately checking interlock.
