Develop a relay ladder diagram for the sequence control of two motor starters using a single normally open momentary contact push button. The sequence of operation is as follows: • Pressing the NO push button (PB) would energize motor starter #1. Releasing the same push button would start motor starter #2. • Pressing a NC push button would stop the motors. • Any overload tripping will stop all motors. Use NEMA symbols and follow the rules for creating relay ladder diagrams.
