4. Product Introduction
The Bently Nevada 3500-60 PWA163179-01G is a 6-channel temperature monitor for the 3500 system. It accepts inputs from RTDs and thermocouples, conditions the signals, and compares them to programmable alarm setpoints for machinery protection.
It monitors bearing metal temperatures, process fluids, and other critical points in turbines, compressors, and motors. The module supports mixed RTD/TC inputs on non-isolated versions and provides reliable data without recorder outputs (use 3500/61 for those). It installs in a standard 3500 rack slot.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No OK LED | Power supply fault | ❌ Low | Measure voltage at module terminals | Verify rack power first |
| Bypass LED active | Channel bypassed in config | ✅ Medium | Check 3500 software status | Remove bypass after verification |
| Erroneous high/low readings | Open sensor or wiring fault | ✅ High | Measure resistance/voltage at inputs | Check field wiring and sensor continuity |
| Alarm not triggering | Setpoint or delay misconfigured | ✅ High | Review configuration file | Adjust setpoints and test |
| No communication | Rack bus or TDI issue | ❌ Low | Check TX/RX LED and TDI | Troubleshoot communications separately |
| Inaccurate temperature | Cold junction compensation error (TC) | ✅ Medium | Verify ambient sensor | Recalibrate or check TC type matching |
Send diagnostic logs, wiring photos, and sensor details if problems continue.
6. Frequently Asked Questions (FAQ)
Does the 3500-60 support both RTD and TC on the same module? Yes on RTD/TC non-isolated I/O versions. You can mix them per channel via configuration software. Isolated TC versions provide channel-to-channel isolation.
Is this module hot-swappable? No. Follow plant procedures to bypass alarms or take the machine offline as needed. Removing under power can cause transient alarms.
What condition is this unit? New Original / New Surplus. We verify serial numbers, perform visual inspection, power-up tests, and basic input simulation on a 3500 rack before shipping.
How do I configure sensor types? Use 3500 Rack Configuration Software. Take photos of existing wiring and note current sensor types before swap. Match exactly to avoid scaling errors.
Can this replace a 3500/60 from an older revision? Usually yes, but confirm I/O module compatibility (non-isolated vs. isolated) and software/firmware versions. Check Bently Nevada documentation for your rack.
What about wiring pitfalls? For RTDs use 3-wire or 4-wire properly compensated. For TCs maintain polarity and use correct compensation cable. Ground loops from poor shielding cause noisy readings — I’ve seen techs chase “bad” modules when the issue was field wiring.
What is the warranty and stock status? Stocked for fast shipping. 1-year warranty on function. Full test documentation provided. Verify your exact I/O needs when ordering.
