🔍 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.

As shown in figure "B" of the illustrated ladder diagram for a programmable logic controller, what statement is true? See illustration EL-0241.

Pressing the start button will automatically cause output loads "Out 1", "Out 2", and "Out 3" to energize without any further inputs.

Pressing the start button will automatically cause output loads "Out 1" and "Out 2" only to energize without any further inputs.
