The objective is to switch the lights for vehicles to red after a button is pressed to enable the pedestrians to cross the road safely. Training content – Simple sequence control systems with sequencers Required Connects 2x Digital I/O Connect Required accessories Programmable logic controller, e.g. in the EduTrainer Universal (Order no. 8065595) or EduTrainer Compact (Order no. 8115009), with at least: – 1 digital inputs – 6 digital outputs For Festo LX Order no. 8147827 For Classroom Manager VT Order no. 8028136 Handling device A two-axis handling device transports workpieces into a clamping device. The handling device is composed of a pneumatic linear axis, a doubleacting stroke cylinder and a parallel gripper. Proximity sensors for determining the end positions are located on the linear axis and the stroke cylinder. Training content – Moving with possibility of collision – Collision avoidance Required Connects 3x Digital I/O Connect Required accessories Programmable logic controller, e.g. in the EduTrainer Universal (Order no. 8065595) or EduTrainer Compact (Order no. 8115009), with at least: – 5 digital inputs – 4 digital outputs For Festo LX Order no. 8147836 For Classroom Manager VT Order no. 8034103 Incremental encoder An incremental encoder is a system composed of numerous sensors for determining changes in position, in this case of the direction of rotation. Three inductive proximity sensors generate signals using the two toothed discs; these signals are used to determine the direction of rotation of the motor. Training content – Mode of operation of an incremental encoder – Programmatic evaluation of incremental encoder signals Required Connects 3x Digital I/O Connect Required accessories Programmable logic controller, e.g. in the EduTrainer Universal (Order no. 8065595) or EduTrainer Compact (Order no. 8115009), with at least: – 3 digital inputs – 8 digital outputs For Festo LX Order no. 8147841 For Classroom Manager VT Order no. 8028132 Coffee vending machine A coffee vending machine offers various coffee mixed drinks to choose from. The feed separator releases a cup after the appropriate selection is made. A sensor detects the cup once it reaches the filling position and forwards the filling signal to the controller. This then controls the filling process based on the preset filling recipe. Training content – Data modules and recipes Required Connects 3x Digital I/O Connect Required accessories Programmable logic controller, e.g. in the EduTrainer Universal (Order no. 8065595) or EduTrainer Compact (Order no. 8115009), with at least: – 4 digital inputs – 8 digital outputs For Festo LX Order no. 8147833 For Classroom Manager VT Order no. 8028140 Coding switch The coding switch connects a specific output as a function of the input signal. A value is entered via two selector switches. A timer is actuated for visualization. Values from 00DEC to 99DEC or from 00HEX to FFHEX can be entered in this timer depending on the selected time system. Training content – Interrogation of a coding switch – Data formats (binary, BCD, HEX) Required Connects 3x Digital I/O Connect Required accessories Programmable logic controller, e.g. in the EduTrainer Universal (Order no. 8065595) or EduTrainer Compact (Order no. 8115009), with at least: – 9 digital inputs – 1 digital output For Festo LX Order no. 8147840 For Classroom Manager VT Order no. 8028131 Linear axis Electric linear axes use a rotary spindle to approach previously defined points with high positional accuracy. The linear axis is actuated by a motor controller that can be switched between forward and reverse operation, as well as between two travel speeds. Three proximity sensors detect the precise position of the slide. Training content – 2-axis, pneumatic, with possibility of collision – Collision avoidance Required Connects 2x Digital I/O Connect Required accessories Programmable logic controller, e.g. in the EduTrainer Universal (Order no. 8065595) or EduTrainer Compact (Order no. 8115009), with at least: – 3 digital inputs – 4 digital outputs For Festo LX Order no. 8147837 For Classroom Manager VT Order no. 8028134 Motor speed adjustment A DC motor drives a sanding disc whose speed can be adjusted to three levels between zero and 2000 rpm. Pressing a broach against the sanding disc simulates a load which reduces the rotational speed as a function of the contact pressure. The control console shows the resultant deviation from the specified rotational speed as a percentage. Training content – Speed adjustment based on disturbance variable and setpoint jumps Required Connects – 1x Digital I/O Connect – 1x Analog In Connect – 1x Analog Out Connect Required accessories Programmable logic controller, e.g. in the EduTrainer Universal (Order no. 8065595) or EduTrainer Compact (Order no. 8115009), with at least: – 1 digital input – 1 digital output – 2 analog inputs – 1 analog output For Festo LX Order no. 8147838 For Classroom Manager VT Order no. 8028142 Tunnel furnace A conveyor transports workpieces through a tunnel furnace. The workpieces remain in the tunnel furnace for a specified time in order to reach the required temperature. To maintain the fixed oven temperature, a sensor measures the temperature and forwards its output signal to a controller. This controls the temperature in the furnace by switching the electric heater on and off in order to compensate for heat loss.
