Instructions: Read the case study thoroughly and make sure to understood it before answering the questions given. You may use any form of CAD tools in answering the problem.

1. Problem: You are designing an electrical instrumentation and control system for a motor control center (MCC) that controls the operation of several motors in a manufacturing facility. The system consists of various electrical components, including circuit breakers, motor starters, relays, and switches. You need to create an electrical control diagram that shows the layout of the components and their interconnections. Assumptions:

• The MCC operates under steady-state conditions.

• The MCC contains circuit breakers, motor starters, and relays for controlling the operation of the motors.

• The MCC contains switches for turning the motors on and off.

• The MCC contains pilot devices, such as pushbuttons and indicator lights, for controlling and monitoring the operation of the motors.

2. Problem: You are designing an electronic system for monitoring the temperature and humidity of a greenhouse. The system uses temperature and humidity sensors to measure the conditions inside the greenhouse and a microcontroller to process the sensor data and control the operation of an exhaust fan. You need to create an instrumentation and control layout that shows the components and their interconnections. Assumptions:

• The system operates continuously to monitor the temperature and humidity of the greenhouse.

• The system uses a temperature sensor and a humidity sensor to measure the conditions inside the greenhouse.

• The system uses a microcontroller to process the sensor data and control the operation of an exhaust fan.

• The system contains an exhaust fan that operates automatically based on the measured temperature and humidity levels.
