🔍 Key Concepts

• Identify which control devices are normally open (NO) and normally closed (NC) in figure A (Stop, Start, M contact, Jog-Run selector). • Understand how a seal-in (holding) circuit works for coil "M" when the jog-run switch is in the run position. • Think about what happens to current flow to coil "M" when the Stop button opens the circuit, and what paths are available when it is released again.

💭 Think About

• When the motor is already running in run mode, through which contacts is coil "M" being fed just before you touch the Stop button? • While the Stop button is pushed, is there any path for current to reach coil "M"? After you release Stop, which contacts are closed and which are open? • Does coil "M" depend only on the Start button being pressed, or does it have another path that can keep it energized without you touching Start? What does that imply after a Stop operation?.

✅ Before You Answer

• Carefully trace the circuit from L1 → Stop → Start/Jog-Run selector → M coil → L2 for each condition (running, Stop pressed, Stop released). • Verify whether the M auxiliary contact (in the jog-run selector path) is providing a holding circuit in the run position. • Confirm if pressing and releasing Stop would cause an automatic restart of the motor without pressing Start again; match that behavior to the choice that describes coil "M".
