8. FAQ – 10 Questions & Answers (Q & A)

Q1: What exactly does the 3500/45 140072‑04 monitor?
A1: It monitors positional variables such as axial shaft position, differential expansion between components, case expansion, and valve travel or actuator position.

Q2: How many channels does the module have?
A2: It has four independent channels.

Q3: What sensor types can be used with it?
A3: It supports AC LVDTs, DC LVDTs, and potentiometers (linear or rotary types).

Q4: What is the operating temperature range?
A4: –30 °C to +65 °C for operating, and –40 °C to +85 °C for storage.

Q5: What is the physical size and weight?
A5: Dimensions are 241.3 mm × 24.4 mm × 99.1 mm, and weight is about 0.20 kg.

Q6: How does the module produce alarms or warnings?
A6: Each channel’s processed signal is compared to user‑set alert and danger thresholds; if exceeded, alerts or shutdown commands may be triggered.

Q7: Can channels be used for different measurement types simultaneously?
A7: Yes — each channel can be configured independently for position, differential, valve, or expansion functions.

Q8: Is this module hot‑swappable?
A8: No, it should not be inserted or removed while powered; power down the rack before module changes.

Q9: How does it integrate into a full machinery protection system?
A9: It resides in the 3500 rack, communicates with relay modules, output modules, and system gateways to form a holistic protection and monitoring topology.

Q10: Are there any constraints in installations (environmental, wiring)?
A10: Yes — proper grounding, shielding of sensor cables, avoidance of sensor cross‑talk, and adherence to environmental limits are essential for reliable performance.
