PURPOSE:To reduce hardware in quantity by prolonging a cycle time as long as the time when a cut-off contact is closed. CONSTITUTION:From (n) units of LPSs and LSSs, one matrix switch each is selected and one row driving of LSS and TPS is selected to open cross points of selected rows by row driver X0. Next, one row driving winding of LSP, JS and TSS and cross points of selected rows of LPS are opened by row driver X0. Then, one row driving winding of LPS, JS and TSS and one cross point column driving winding are selected, so that one cross point of LPS, JS and TSS will be closed by column driver Y0. Next, one cross point of LSS and TPS is closed and one row driving winding and cut-off driving winding are selected to close a selected cut-off contact. |
