Abstract
PURPOSE:To economize a check system by saving a checking circuit by using one checking circuit for an earth check and on/off check. CONSTITUTION:As for earth checking circuit GD and switch-driver on/off checking circuit SWD, their input levels to be checked are equal because of the earth level or no-earth level. Further, since an on/off check on switch driver SW-DR is made after an earth check on driving line DL of path selection relay PSR, two checks differ in time and those checking circuit are never used simultaneously. Therefore, circuit GD makes a logical judgement by an earth input and when the result of the earth check is OK, the controller drives mercury relay TR to change its contact tr deg. over. Consequently, driver SW-DR is connected to the input of circuit GD by switching to make the on/off check on SW-DR.
