The BENTLY 3500/15-05-05-CN is the module that keeps your vibration monitoring online. This specific option code configuration (-05-05-CN) indicates a high-voltage AC/DC input supply, meaning it can take anything from 85-264 VAC or 88-300 VDC. That flexibility matters in plants where DC backup is standard. The “CN” suffix? Likably a factory configuration variant—maybe conformal coating or special calibration, though Bently isn’t transparent on all option codes. What’s non-negotiable: it occupies two full slots on the left side of the rack, and if you’re running redundant power (which you should on critical machinery), you need two of these, each fed from separate sources. Output is 70W max, shared between them. That’s enough for a fully loaded rack, but barely—so if you’re adding communication processors or relays, check the power budget.   Installation & Configuration Guide Swapping a 3500/15 isn’t like changing a lightbulb. The rack backplane is live if the other supply is powered, so caution is mandatory. Phase 1: Pre-Installation: ⚠️ Identify which power supply in the redundant pair you’re replacing. If only one supply is installed, the rack will shut down when you remove it—plan for a machine outage. If redundant, you can work live, but verify the second supply is functional and taking the full load. Tools: #1 Phillips, flathead screwdriver for terminals, multimeter, ESD strap. Critical: Note the wiring configuration: L1, L2/N, and Ground. Photograph the terminals. Verify the new 3500/15-05-05-CN option codes match the old unit—mixing input voltage ranges is a bad idea. Phase 2: Removal (Hot Swap – Redundant Only): With both supplies running, locate the faulty unit. Loosen the two captive screws at the top and bottom of the module faceplate. Pull the module straight out using the handle—it disconnects from the backplane. Inspect the backplane connector for burn marks or bent pins. If it’s the only supply, de-energize the incoming AC/DC feed first, then pull the module. Phase 3: Installation: ESD strap on. Slide the new BENTLY 3500/15-05-05-CN into the empty slot along the guide rails. Push firmly but evenly until the backplane connector seats fully. Tighten the captive screws to secure the module—torque to approximately 0.8 N·m (7 in-lb); overtightening strips the rack threads. CRITICAL: Reconnect field wiring exactly as photographed. For AC inputs, verify L1 and L2 polarity isn’t reversed (some older plants swap legs). For DC inputs, observe polarity—the module is reverse-polarity protected, but why test it? Phase 4: Power-On & Verification: Re-energize the incoming supply. Observe the front-panel LEDs: “OK” should illuminate steady green within 2-3 seconds. The “INPUT OK” LED confirms the feed is present. Access the 3500 rack configuration software (Rack Configuration Software or System 1). Navigate to the power supply status screen. Verify the new 3500/15 is recognized and shows “OK” status. If the rack shows a power supply fault, cycle the input power once. Still faulted? Check wiring and backplane connection.   Frequently Asked Questions (FAQ) 1. What do the option codes -05-05-CN actually mean on the 3500/15? Bently Nevada’s option codes are cryptic. The first “-05” typically indicates the input voltage range. In this case, -05 maps to the high-voltage universal input (85-264 VAC / 88-300 VDC). The second “-05” often denotes the connector type—probably standard screw terminals. The “-CN” is likely a factory configuration identifier; it might indicate the module was built for a specific regional standard or had a particular calibration. Honestly, unless you’re Bently service, you treat the full string as the ordering number. The 106M1079-01 is the assembly drawing number, confirming the build revision. 2. Can I mix a -05-05-CN power supply with an older -01 revision in the same rack? Technically yes, for redundancy. The rack doesn’t care about option codes as long as both supplies are functional and output the same voltages. However, mixing input voltage ranges (e.g., one high-voltage AC and one 24V DC) is fine—they’re just feeding from different sources. The rack draws power from whichever is active. For long-term reliability, matching revisions is better, but in a pinch, a 3500/15-05-05-CN will work alongside any other 3500/15 variant. 3. What happens if the power supply fails and I have no redundant unit? The rack dies. Immediately. The 3500 system has no internal power storage. When the single supply drops, all monitoring stops, relay outputs de-energize, and communication is lost. If that supply was powering a trip circuit (via a relay module), you’ll get a false trip condition—or worse, a failure to trip when needed. This is why critical machinery always runs redundant 3500/15 supplies. If you’re in this situation, you need to schedule an outage now. 4. The “OK” LED is flashing amber. What’s that mean? A flashing amber “OK” LED on a 3500/15 indicates a power supply fault—usually overcurrent or over-temperature. First, feel the module faceplate. Hot? Check ambient cabinet temperature and ensure ventilation isn’t blocked. If it’s cool, the issue is likely internal overload or component failure. Check the rack’s total power draw in the software. If it’s near 70W, you’re maxed out. Replace the supply; if the new one also faults, suspect a backplane short or a failing module elsewhere in the rack drawing excessive current. 5. Is the 3500/15-05-05-CN considered obsolete? No, but it’s long in the tooth. The 3500 platform is still actively supported by Bently Nevada (Baker Hughes), though they’ve introduced newer platforms like the 3500/20 series and System 1 software. The 3500/15 power supply is still manufactured and available as a spare part. However, “New Surplus” stock like this is often priced lower than factory-direct, making it a good procurement option for plant spares. 6. Can I use this power supply in a 3500/5 frame? No. The 3500/5 frame is an older, smaller rack. The 3500/15 is specifically designed for the full-size 3500 rack (19-inch). The backplane connectors and slot spacing are different. Check your rack part number—if it’s a 3500/05, you need a different power supply (likely the 3500/10 or 3500/12, depending on age). 1C31113G06 PLC EMERSON 1C31116G01 EMERSON 1C31116G02 PLC EMERSON 1C31116G03 PLC EMERSON 1C31125G01 PLC EMERSON Email: [email protected] Phone: 86 15340683922 Sales:Wu Jiedong Our products are guaranteed for 1 year, with new and original production stopped and imported spare parts.
