Frequently Asked Questions (QA)

Q1: What types of sensors does this module support?
A1: It supports proximity probes for displacement measurement and seismic transducers for vibration detection.

Q2: How many separate channels can it monitor?
A2: It monitors four independent channels simultaneously, offering broad coverage of rotating machinery.

Q3: What monitoring outputs are available for system integration?
A3: The module provides 4–20 mA analog outputs for each channel and buffered voltage outputs suitable for control systems.

Q4: What signal processing capabilities are included?
A4: It includes true‑peak, RMS, gap, and harmonic (1×, 2×, not‑1×) calculations for detailed analysis.

Q5: Is this unit safe for explosive or hazardous areas?
A5: Yes. It is rated for Zone 2 operation, suitable for areas with occasional flammable atmospheres.

Q6: How much power does it consume?
A6: Less than 5 watts, which helps reduce overall rack power load.

Q7: What are the operating temperature limits?
A7: It reliably functions between −30 °C and +65 °C, handling wide-range environments.

Q8: What type of maintenance does it require?
A8: It requires minimal maintenance—mainly routine checks of signal quality and occasional firmware updates.

Q9: Can the module be hot-swapped while the rack is powered?
A9: No. Rack power must be turned off before insertion or removal to avoid damage.

Q10: Which product series does this belong to?
A10: It is part of the 3500 series, a modular protection family devoted to critical rotating machinery monitoring.
