<p>PURPOSE:To eliminate use of any complex sensing means and liberate from limitation about combination of the engine and an apparatus rotated. CONSTITUTION:A car device for separating the apparatus rotated comprises No.1 sensing means 16 to generate No.1 signal having a certain voltage level when the engine is in operation, No.2 sensing means 20 to generate No.2 electric signal having a certain voltage level when apparatus rotated is out of operation, a judging means 24 to generate a failure signal indicating that the apparatus is failed according to the logical conditions of No.1 and No.2 electric signals under which the apparatus operates, and a control notifying means 28 to control an electromagnetic clutch 14, which separates the apparatus from a drive belt on the basis of the failure signal, and to give a notice that the apparatus is in failure.</p> |
