🔍 Key Concepts

• Seal-in or latching circuit using an internal relay (IR1) with a Start and Stop pushbutton • How IR1 controls each rung feeding Out 1, Out 2, and Out 3 • Which outputs require additional input contacts besides IR1 to energize

💭 Think About

• Trace the power flow when the Start button is pressed: which coil energizes first, and what contact then keeps it energized even after Start is released? • Look at each output rung: for Out 1, Out 2, and Out 3, count how many series contacts must all be closed when only the Start button has been pressed. • Ask yourself: after pressing Start and then letting go (without touching any other inputs), which output coils have all of their required contacts closed?

✅ Before You Answer

• Verify which rungs contain only IR1 (or contacts that are guaranteed to be closed after Start) in series with an output coil. • Check which outputs have an extra contact labeled "Input for output 2" or "Input for output 3" that would still be open if no other buttons/sensors are operated. • Confirm that the Stop contact is normally closed, so after Start is pressed and released, only the outputs fully controlled by IR1 alone will stay energized.
