In the lesson on the control unit all the links between the status of the sensors and the actuator drives are dealt with one by one The control system is explained in this way using the exercises In order to complete the instruction on the control unit all the panels which are part of the control unit must be connected so that all the measurement exercises can be carried out Depending on the configurations described earlier in this chapter the CBT program checks whether a specific component has been con nected If the fixed setup with wiring option has been selected the student can always continue with the lesson on the control unit the CBT program assumes that all the connections are in place For the other two options the student himself must have connected the panels The CBT program assumes that the component is connected if the component is displayed in the circuit diagram when the student starts on the control system or if all the connections have been established in the lesson on the component RESO control unit LE ER A richer mixture is required when the motor is running at full load and during acceleration The control unit determines the position of the throttle A output voltage from this sensor higher than 4 5 volts identifies full speed The control unit identifies acceleration by the fact that the output voltage of the throttle position sensor suddenly increases SV div 2ms div at the moment
