情境
A single-leaf sliding gate uses a 230 V AC motor with a run capacitor. The control circuit steps down to 24 V AC, uses a start/stop pushbutton station, and stops automatically when the open limit switch trips.

看懂背後的決策。
01
Use a 24 V control transformer for safe pushbutton wiring
02
Keep a run capacitor across the motor terminals to maintain torque
03
Place a NC limit switch in series with the relay coil for end-stop safety
Single-direction gate or door motor starters where a run capacitor and one end-stop limit are required.
