14. which of the following statements about the basic rules to be followed when converting a ladder diagram into a logic diagram that can be loaded into the PLC is FALSE? Each line of logic must end with a coil. Only one set of contacts can be assigned to any input. Any coil assigned to the same number as an output will control that output. Each relay can have an infinite number of contacts. a. b. С. d.

Question
### PLC Programming and Electrical Safety #### Question 14: Which of the following statements about the basic rules to be followed when converting a ladder diagram into a logic diagram that can be loaded into the PLC is FALSE? - a. Each line of logic must end with a coil. - b. Only one set of contacts can be assigned to any input. - c. Any coil assigned to the same number as an output will control that output. - d. Each relay can have an infinite number of contacts. #### Question 15: In the figure below showing an explosionproof installation, the arrows point to the _______. (Graphical representation described) The diagram shows a setup with multiple components connected through wiring. At certain points in the diagram, arrows are pointing to specific parts that need to be identified. Options: - a. breakers - b. seals - c. fuses - d. controllers #### Question 16: Which of the following is NOT a recommended general procedure for dealing with harmonics? - a. Increase the 60-hertz part of the neutral current. - b. Pull extra neutral conductors. - c. Derate the amount of load on the transformer. - d. Add harmonic filters at the load. **Detailed Description of Diagram for Question 15:** The diagram illustrates an explosionproof installation which is typically used in hazardous environments to prevent ignitions and explosions. It consists of various components such as a motor, wiring conduits, and boxes. The arrows highlight critical points in the system which are essential for ensuring safety. The choices indicate elements that are integral to maintaining a safe and reliable electrical system in such environments.
