FAQ (10 Q&A)

1. Q: What exactly does the 3500/40M module monitor?
   A: It monitors radial vibration, thrust position, eccentricity, differential expansion, and REBAM diagnostics—all via four proximity channels.

2. Q: Why is the 125680‑01 I/O module included?
   A: It provides internal termination and I/O connection to simplify installation and ensure clean signal handling.

3. Q: Can it be replaced while the system is running?
   A: Yes—its hot‑swappable design ensures continuous operation without shutting down the rack.

4. Q: How accurate are its measurements?
   A: Typically within ± 0.33 % of full scale, with a maximum error of ± 1 %.

5. Q: What environments is it built for?
   A: Industrial and hazardous environments—compliant with API 670 and available with ATEX, IECEx, CSA approvals.

6. Q: How are alarms handled?
   A: Via 3500 Rack Configuration Software, you set alert and danger thresholds and configure relay outputs.

7. Q: What sensors can connect to it?
   A: Standard proximity transducers like the 3300 XL series are supported.

8. Q: What is REBAM?
   A: It’s Rolling Element Bearing Analysis Measurement—a diagnostics method for detecting bearing issues.

9. Q: Can this module communicate with control systems?
   A: Yes—through buffered sensor outputs, 4‑20 mA recorder outputs, and can interface via Modbus or gateways to SCADA/PLCs.

10. Q: What is the typical power consumption?
    A: Approximately 7–7.7 watts at 24 V DC.
