4. FAQ

Q1: What sensors are compatible with the 3500/05‑01‑03‑01?
A1: It supports standard IEPE/ICP accelerometers providing constant current excitation, as well as voltage outputs from compatible sensors.

Q2: Can the module be replaced while the system is online?
A2: Yes. The 3500 series is hot‑swappable—you can swap a faulty module without shutting down the rack or compromising protection.

Q3: How are vibration levels trended over time?
A3: Analog outputs (such as 4–20 mA) can be connected to historian or control systems for trending; digital I/O can be used for automated data capture.

Q4: Does it include presets for alarm and shutdown thresholds?
A4: The module ships with conservative, factory‑default thresholds; however, users typically configure alarm and trip levels based on plant‑specific vibration baselines.

Q5: What happens if power is lost?
A5: Upon loss of power, the module’s relays will safely de‑energize, initiating trip outputs by default—ensuring fail‑safe operation.

Q6: What maintenance is required?
A6: Routine maintenance is minimal—periodic calibration checks are recommended, along with ensuring probe cables and connectors remain clean and secure.

Q7: Is there diagnostic feedback available?
A7: Yes. LEDs on the front panel indicate channel status and alarm/trip conditions; diagnostics may also be polled via serial link if configured.

Q8: How broad is the temperature range for use?
A8: The module is rated for −40 °C to +70 °C, suitable for most indoor and moderately challenging environments.

Q9: Can one module handle both velocity and acceleration measurement simultaneously?
A9: This particular model is configured only for acceleration (ICP); for velocity or combined signals, alternate or additional modules are required.

Q10: Is there surge or EMI protection?
A10: Yes. The design includes transient suppression and filtering to maintain operation in electrically noisy plants.
