PURPOSE:To provide a well matched safe indication even in the case of interlocked control by providing a receiving circuit section for providing a priority to an operating data, a received signal. judging section, and a judged state indicating section. CONSTITUTION:A receiving circuit section 19 in an operating unit 15 functions to produce a logical sum of signals provided from control units and a priority is imparted to an operating data. In other words, when a data representing start of any one closing operation is received at start of operation. a judging section 20 commands a display section 21 to display 'under closing operation'. Furthermore, even if the control unit for a motor switching machine having a short operating time provides a 'fully closed stop' data, 'under closing operation' is displayed so long as a data representing at least one 'under closing operation' is being received and the 'fully closed stop' is displayed when the 'under closing operation' data is not received. Consequently, a well matched display is provided, 'under operation' is displayed so long as one 'under operation' data is provided resulting in an easy and safe display. |
