Abstract

PURPOSE: To obtain elevation on reliability for detecting and inspection, not using power output contact point for inspection and constant watching, by finding abnormal circuit such as breaking in output power auxiliary relay through constant watching and instantly given alarming signal on abnormal circuit.
CONSTITUTION: By output power of transistor type input DC voltage detecting circuit DC1W3, transistor Tr11W31 are on-off-controlled. By output power of this transistor Tr11W31, output power auxiliary relay X1WX3 are drove and also controlled for inspection transistor Tr12W32. Each collector of transister Tr12W32 is connected with each power input terminal of "or" circuit OR and "and" circuit AND. By output power of High level of AND, coil of relay OK is enlivened, and furthermore by output of High level of OR, start timer T3 its action and send out output power after fixed time and energize coil of relay TX.
