Ordering & Compatibility
- Model: 3500/40 – Proximitor Monitor
- I/O Module Type: -03 = Internal Barriers & Internal Terminations
- Agency Approval: -02 = ATEX / IECEx / CSA (Class 1, Zone 2)
- Required Software: 3500/01 v2.50, 3500/02 v2.20, 3500/03 v1.21 (or later)
- REBAM mode requires: 3500/40M Firmware Rev 2.1, 3500/01 v3.30, 3500/02 v2.40, 3500/03 v1.40, DM2000 v3.40
- External termination blocks must be ordered separately – not compatible with internal termination I/O.
- For internal barrier option, refer to Bently Nevada document 141495.
Installation, Setup & Maintenance
- Mounting: Standard 3500 rack – plug‑and‑play with rear connectors.
- Configuration: 3500 Rack Configuration Software (user‑programmable alarms).
- Diagnostics: Front panel LEDs (OK, TX/RX, Bypass) and buffered transducer outputs for each channel.
- Maintenance: No routine calibration; firmware upgrades via 3500 software.
- No external barriers needed – internal barriers simplify wiring.
Certifications & Warranty
- ATEX / IECEx / CSA – Zone 2, Class 1 hazardous areas.
- 12‑month factory warranty – new & original in factory packing.
