Design a Forward/Reverse motor control diagram with the following specifications.
A motor turns a large fan. The fan is mechanical load with a lot of momentum. This means the motor might continue to coast for a substantial amount of time after the sto button had been pressed.
This could be problematic if an operator were to try to reverse the motor direction without waiting for the fan to stop turning.
If the fan was still coasting forward and the "Reverse" pushbutton was pressed, the motor would struggle to overcome that inertia of the large fan as it tried to begin turning in reverse, drawing excessive current and potentially reducing the life of the motor, driv mechanisms, and fan.
Develop a control system to a have a delay function in this motor control system to prevent such a premature startup from happening.
Once the motor is running the motor will not run in the opposite direction until enough time has passed for the motor to come to a complete stop.
The motor will have a stop button. If the stop button is pressed, the motor will not be able to be started in the opposite direction until the motor has completely stopped running. To be clear, the stop button cannot simply be pressed followed by the start button of the opposite direction. The same time delay necessary for the motor to stop must still apply.
A pilot light will indicate when the motor is running in the forward direction. A second pilot light will indicate when the motor is running in the reverse direction. A third pilot light will indicate when a timing delay is taking place.
A two hand no-tie-down start system for forward and reverse must be utilized.
A run/jog function must be included.
