A temperature sensor and a pressure sensor (consider NO switch) are used to control a mixer which consists of an AC motor. When the set pressure and temperature are achieved, the motor will automatically turn on. In addition, the motor can be turned on using manual pushbutton A, whereas the releasing action of the pushbutton A will turn on the motor. The motor will not turn on as long as the manual start pushbutton is pressed. i) Provide a list of components and address table for the required items.

What are the functions of a Transfer Switch: (Select all answers that apply) Group of answer choices A. Shifts electrical power from the normal utility power source to the standby power source B. Isolates the utility source from the standby source in such a way that there is no feedback from the generator to the utility’s system or vice versa C. When normal power is restored, the automatic transfer switch resets itself and is ready for the next power outage D. Provides for measuring of power usage by the residents during periods of brownouts with the generator offline.

Which of the following statements is true for an SCR. O A. It is an on-only controllable switch, which is turned on by a gating signal and cannot be turned off externally; only system conditions can turn off the device once it is on O B. None of the other choices are correct O C. It is a controllable switch, which is turned on by applying a gating signal and is turned off when the gating is removed O D. It is an off-only controllable switch, which is turned off by a gating signal as needed O E. It is an on-off controllable switch, which is turned on and off by a gating signal as needed
