Or . The safety screen is opened. Or . .The ram is down (limit switch S3 actuated) Raising the ram: If the ram is down (limit switch S3 actuated), it is raised by the eccentric drive. The safety .screen can be opened and both two-hand switches released The machining cycle is completed when the ram reaches the home position (limit switch S6 actuated) The designer needs for ........conditional output boxes for drawing the ASM-chart for the controller of the aforementioned system 0 C 2 3 O O O O O Oarrow_forward
