Référence rapide d'installation

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.

Dépannage

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.

Ce qu'en disent les utilisateurs

“Our dairy plant does high-pressure hot water washdowns every shift. Regular IP65 buttons lasted maybe 6 months. Switched to Siemens SIRIUS ACT with IP69K and they've survived 18 months of daily abuse so far. Worth every penny of the premium.”

“If you are already in the Siemens ecosystem (S7 PLC, TIA Portal), the SIRIUS ACT buttons integrate nicely. The metal front ring feels premium. Downside is they are pricier than Schneider/Eaton for the same function.”
