- 1.) LIGHT CURTAIN DISTANCE CALCULATIONSA mechanical press has a stopping time for its press-brake mechanism of 0.39 sec and a stopping time for the control circuit of 0.06 sec. The brake monitor is set for 0.58 sec, and the minimum object sensitivity is 0.78 in. Calculate the minimum safe distance that the light curtain can be installed from the press. 2.) A robot system has a protective barrier enclosing the work cell area. The total time for the system to come to a full halt after power is removed is 4 seconds, and an additional distance of 1.2 meter is required because of the height of the guard gate would allow operators to reach over it.Determine the minimum distance from the guard gate to the closed part of the robot work envelope, in meters.NOTE: 1 meter = 1,000 millimetersarrow_forward3.

This system includes a gate that goes up or down, a motor to actuate the gate (pull, push) and sensors to collect information (gate open contact, gate closed contact). The sensors are all similar, each signaling to its controller that a contact has taken place. The user has a remote control to control with just two buttons: open, close. The operating principle of the system is as follows. Suppose the gate is closed. The user opens the gate by pressing the Open button on his remote control. He can stop opening by pressing the Open button again, the motor stops. Otherwise, the gate opens completely and triggers a Gate Open sensor which causes the motor to stop. Pressing the Close button causes the gate to close if it is open (partially or fully). The closing can be stopped by pressing the Close button again, the motor stops. Otherwise, the gate closes completely and triggers a Gate Closed sensor which causes the engine…arrow_forward- Switching, Cords and Cables, Motors, and Related Systems 15.a.
