情境
A residential double-leaf swing gate uses two 230 V single-phase motors with run capacitors. The control panel provides pushbutton open/close commands, stop buttons, end-of-travel limit switches, a 24 V control transformer and a warning lamp.

看懂背後的決策。
01
Use two separate relays (K1/K2) for open and close commands, each with a relay_spdt contact feeding both motors.
02
Include a 230/24 V control transformer and fuses for safe low-voltage controls.
03
Add run capacitors across each motor to model permanent split-capacitor operation.
04
Use limit switches in series with each relay coil to stop at end positions.
