在产Harmony XB4 Illuminated Red Push Button 24V LED
Illuminated red flush push button with integrated 24V LED for Schneider Harmony XB4 series. 22mm cutout, IP66 rated. Visual confirmation of stop/fault state.
常见应用
Illuminated red push button that lights up to confirm the machine is stopped or a fault is present. The red LED provides clear visual status — lit means the stop circuit is active or an alarm condition exists. Common on packaging lines, conveyor systems, and CNC machine auxiliary panels where operators need immediate confirmation that the stop command was received. Pairs with the green illuminated ZB4-BW333 for a matched start/stop set. Uses a 1NC contact with ZB4-BZ102 block, so the circuit breaks on press — standard fail-safe wiring for stop functions.

这是一个模块化组件。要完成组装，您可能还需要：
安装快速参考
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

故障排除
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
