상황
A sliding gate uses a 400 V three-phase motor. Reversing contactors KM1/KM2 are interlocked to prevent simultaneous forward and reverse, while a 24 V control circuit with safety edge stops operation if the edge is pressed.

01
Use reversing contactors with electrical interlock to swap L1 and L3 for motor reversal.
02
Derive 24 V control voltage from a transformer to isolate pushbuttons and safety edge from the 400 V supply.
03
Place safety edge and STOP pushbuttons in series with both direction commands.
