FAQ
Q1: How to select a suitable explosion-proof push button?
A1: Selection should be based on the following criteria:
- Explosion-proof & IP Ratings: Match the marking and IP rating to your site’s hazardous substances (gases/dust).
- Function & Build: Select function (e.g., NO/Start, NC/Stop, E-Stop, illuminated), material, and color.
- Contacts: Specify the number of NO/NC contact sets needed.
- Certifications: Confirm compliance with target market standards (e.g., ATEX, IECEx).
Q2: What are the specific requirements for an ex emergency stop button?
A2: Emergency stop buttons must comply with mandatory safety standards and possess:
- Direct-Action Contact Break: Mechanically severs the load circuit.
- Maintained Locked State: Requires a manual reset action (e.g., twist-to-release).
- High-Visibility Design: Red mushroom head, ideally on a yellow background.
Q3: Can operational labels be temporarily attached to the housing of flameproof push buttons in a chemical plant?
A3: Not recommended. Labels can impair heat dissipation and block critical markings. If required, use temperature-resistant and anti-static materials. The best practice is to select buttons with a custom nameplate slot or laser engraving.
Q4: What could be the potential reasons if the equipment does not respond after pressing the buttons?
A4: Troubleshoot following these steps (ensure power is isolated before proceeding):
- Check Wiring: Inspect for loose or disconnected internal wiring.
- Check Contacts: Examine if the contacts are oxidized or burnt.
- Check the Load: Verify the health of the relay or contactor coil being controlled.
- Check the Button Mechanism: Determine if the mechanical assembly is jammed or damaged.
