When start button is pressed than coil MCR get charged and NO contact of MCR changes to NC.
Hold on contact in parallel to start will get NC and coil MCR will be charged always even start button gets released.
The MCR contact in series with light get NC and the light will glow up.

Design a control circuit to energize 3 lights (red, amber, green) . The red light will turn on as soon as a Start button is pressed. Two seconds later, the amber light will turn on,. The green light will turn on 2 seconds after the amber light. After the green light is on for 2 ms, all lights should go off. This cycle should repeat until a STOP button is pressed. Draw the sequence bar chart for this circuit as...

4.1) Application Scenario #1 A drilling tool (T) is required to operate in two different modes, START/STOP or PULSE, depending on the selection made by the user via three push-buttons (START push-button, STOP push-button, and PULSE push-button). Assume that the real application elements and the prototype elements from the PLC panel relate to each other according to the definitions from Table 1. Real Application Elements START push-button STOP...

Q1 (30 pts) Design a state-based PLC program to control a motor. The system specification is as follows. • Press a normally open push button, the motor will start. Motor stop will stop after 5 minutes or a normally close push button is pressed. . When the motor is running, a read light is ON. When the motor is stopped, a green light is ON. Use the "Fail Safe" concept, i.e., if the wire of...
