Frequently Asked Questions

• Q: Can I use this communicator on a Foundation Fieldbus device?A: Yes, the TREXCFPNAWS3 includes both HART and Foundation Fieldbus applications (F model).
• Q: Is the device intrinsically safe for gas environments?A: Yes, it is intrinsically safe. However, it carries NA (No Approval) certification, meaning it meets intrinsic safety standards without specific regional marks.
• Q: How do I synchronize data with AMS Device Manager?A: You can sync wirelessly or via USB connection. The device automatically communicates with the host software.
• Q: What is the real-world battery life?A: Typical use exceeds 8 hours. Intensive wireless use may reduce battery time.
• Q: Does it support older HART devices?A: Yes, it supports HART protocol devices, both old and new revisions.
• Q: Can the touchscreen be used with gloves?A: Yes, it features a resistive touchscreen, ideal for gloved hands in industrial settings.
• Q: What does the S3 support include?A: 3-year standard support covers software updates and technical assistance.
• Q: How rugged is the device?A: It passes a 1-meter drop test onto concrete and has IP54 ingress protection.
• Q: Can I power a 2-wire transmitter with this device?A: Yes, the power the loop functionality lets you power and communicate with the device simultaneously.
• Q: Which memory is used for applications?A: 512 MB RAM for active tasks, 2GB NAND for OS, and 32GB extended flash for data storage.

Buying Guide & Experience Tips

• Selecting the right model: Choose TREXCFPNAWS3 if you need HART, Fieldbus, and wireless. For HART-only with no wireless, consider other variants.
• Battery strategy: The Li-Ion module is rechargeable. Keep a spare for shift-long operations beyond 8 hours.
• Software support: The 3-year S3 support is essential for staying current with device descriptions and features.
• Diagnostic use: Leverage valve diagnostics to predict failures before they occur, reducing unplanned downtime.
• Wireless tip: Use wireless sync in safe areas to quickly upload batch data without returning to the control room.
• Storage: Store in a clean, dry place within specified temperature range to prolong battery life.
