Beginner 09 — Conveyor with auto stop

Briefing

Pull everything together. Tap START — MOTOR latches on. After 3 seconds, a timer auto-shuts the MOTOR off. That's a real industrial pattern: short-cycle a conveyor with a single button press. Three rungs: a SET on START, a TON enabled by MOTOR, and a RESET when the timer's .Q goes true.

Objectives

• Tap START → MOTOR runs
• After ~3 seconds without further input, MOTOR shuts off automatically

   Once T_RUN.Q goes true, the RESET drops MOTOR

2. #2Pulse START → MOTOR on

   A momentary START latches MOTOR on

3. #3Mid-cycle (1.5 s) → MOTOR still on
