Question 1 Figure 4 shows the conveyor systems actuate by a 3 phase induction motor (3-phase 415 volts 50 Hz star connection). The conveyor belt is running in forward and reverse direction. • The conveyor will move FORWARD direction when the forward pushbutton S1 (N/O) is pressed then released. • The stop push button S3 (N/C) will stop the motor regardless of which direction it is turning. • The conveyor will move REVERSE direction when the reverse pushbutton S2 (N/O) is pressed then released. • Safety requirement: o Electrical interlock for RIGHT and LEFT movement Crane will be stopped if: Conveyor Thermal overload relay F1 is tripped Emergency stopped pushbutton S4 is actuated FORWARD CONTROL PANEL STOP REVERSE EMERGENCY STOP Figure 4: Conveyor system BOX Motor MOTOR RUNNING a) Draw the power circuit for direct on line reversing motor starter (forward reverse) of an induction motor.
