<P>PROBLEM TO BE SOLVED: To solve the cumbersome problem that low-limit overload detection sensitivity corresponding to the size of an individual shutter apparatus has to be input as an initial value into the individual shutter apparatus. <P>SOLUTION: An initial setting mode is provided before a normal operation of a shutter apparatus; a shutter full-closing operation is performed by low low-limit overload detection sensitivity set without reference to the size of the shutter apparatus in the initial setting mode; and the low-limit overload detection sensitivity for use in the subsequent normal operation is determined, so that the low-limit overload detection sensitivity can be input into the apparatus in such a manner as to correspond to the size of the individual shutter apparatus. <P>COPYRIGHT: (C)2013,JPO&INPIT |
