Application-Specific FAQ
Q: Is the 3500/22M compatible with older 3500/22 racks?
A: Yes. The 3500/22M is backward-compatible with existing 3500 rack infrastructure. No rack modification is required for direct replacement.
Q: Which proximity probes are supported?
A: The module is designed for Bently Nevada 3300 XL 8mm and 5mm probes, as well as 7200 series probes. Third-party probes may require calibration verification.
Q: Can this module be used in SIL 2 safety instrumented systems?
A: The 3500/22M supports SIL 2 capable architectures per IEC 61508 when installed and validated according to Bently Nevada’s functional safety manual.
Q: What is the warranty on this unit?
A: Konmask.com provides a standard 90-day functional warranty. Extended warranty and exchange programs are available — contact us for details.
Q: Do you provide export documentation for international orders?
A: Yes. We provide commercial invoices, packing lists, and certificates of origin. HS Code 9031.80 applies to this product class for most jurisdictions.
