Lo scenario
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.
Cosa contiene questo disegno
Leggi le decisioni che ne stanno alla base.
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.
