(a) As an engineer, you are assigned to construct of the following system by implementing relay holding circuit technique. The process sequences are as follow: i). Construct the relay ladder diagram with optimum control system for abovementioned system clearly with correct label of the relay pin numbers. [C4, SP4] [8 marks] ii). Construct the hardwire control circuit and draw it to the Appendix attached. [C4,SP4] [7 marks] (b) Figure Q1(b) shows a Logic Gate Circuit diagram. Construct a PLC ladder diagram from the given logic gate circuit. [C3, SP4] [5 marks] Figure Q1(b): Logic Gate Circuit
