Bently Nevada 21000 Probe: On-Site Testing for Industrial Automation

Comprehensive On-Site Testing: Verifying Bently Nevada 21000 Probe Systems for Reliable Industrial Automation

Installing Bently Nevada 21000 Series Probe Housings is crucial for machine protection. However, installation is just the start. Thorough on-site testing confirms mechanical integrity and signal quality. This verification is essential for reliable industrial automation systems. It ensures accurate data for predictive maintenance and machinery diagnostics.

The Critical Role of Commissioning Checks in Control Systems

Testing after installation validates the entire proximity probe system. It ensures probe housings are secure and properly aligned. Moreover, it confirms the proximity probes maintain the correct target gaps. Reliable signal paths are vital for integrating with a DCS or PLC. Data accuracy is the foundation of effective machine protection.

Bently Nevada 21000 Probe: On-Site Testing for Industrial Automation

Essential Pre-Test Safety and Equipment Preparation

Safety must always come first in factory automation. Always follow Lockout/Tagout (LOTO) procedures. Confirm the machinery is completely locked down and cannot move. Verify that the Bently Nevada probe model matches the housing and proximitor. Experienced field engineers prioritize calibrated tools.

Necessary Tools for Field Testing:

Calibrated digital multimeter (DMM).

A precision proximity probe gap meter.

Oscilloscope or a portable vibration analyzer.

Detailed Mechanical Verification of Probe Housing Integrity

Begin with a thorough mechanical inspection. Ensure the 21000 housing is mounted perfectly perpendicular to the shaft. Proper alignment minimizes signal distortion. Check all O-ring seals for any potential contamination. Furthermore, confirm that all mounting bolts meet the specified torque values. Incorrect torque can lead to housing shift during operation. Misalignment exceeding 1° to 2° significantly impacts eddy-current sensor accuracy.

Electrical Continuity: A Cornerstone of Signal Trust

After mechanical checks, electrical testing confirms system health. Technicians must verify proper cable routing. This includes checking for correct shielding and grounding practices. Use a DMM to test continuity from the probe to the proximitor terminals. Look for abnormal resistance readings. High resistance often indicates damaged insulation or loose connections. This testing prevents hidden issues common from improper cable pulling during setup.

Setting the Precise Gap Voltage for Optimal Performance

The proximity probe’s gap voltage is the system’s baseline. Power the system and adjust the probe until the target DC voltage is achieved. This is typically -10  VDC± 1  VDC for Bently Nevada systems. Always measure this voltage at the proximitor output. In addition, perform a linear range check. Apply a known shim offset and verify that the voltage change matches the probe’s calibration curve. This confirms the system operates within its most accurate range.

⚙️ Practical Tip: Staying strictly within the linear operating range prevents signal clipping. This ensures that the vibration monitoring system delivers true amplitude readings.

Dynamic Signal Validation and Noise Assessment

Dynamic testing proves the system performs under load. If possible, perform a slow machine roll or a “bump test.” Observe the waveform stability on the vibration monitor. A clean signal is critical for accurate fault detection. Moreover, check for signal noise spikes or drift. Excessive AC noise when the machine is stationary often points to grounding or shielding problems. A stable DC bias confirms system integrity for dynamic monitoring.

System Integration and Monitor Calibration for Control Systems

The final phase involves integrating the monitoring data into your control systems. Verify that the monitor’s scaling precisely matches the probe and proximitor specifications. Alarm and trip setpoints must align with the site’s condition monitoring strategy. Conduct a full loop test: Sensor → Proximitor →Monitor→ DCS. This confirms real-time readings transfer accurately. It also verifies that simulated alarm and trip events successfully activate plant protection protocols.

Establishing a Reliable Baseline and Documentation

Complete the commissioning by collecting baseline data. Record stable vibration and position readings under normal, no-load conditions. Save all waveform and spectrum data as reference files. Finally, log all final gap voltages and physical orientations. Thorough documentation supports warranty compliance and API 670 acceptance. This baseline is invaluable for long-term predictive maintenance programs.

After completing all checks—from mechanical seating to loop testing with the main DCS—we achieved a stable baseline. This rigorous process guaranteed that the turbine’s protection system was fully functional before the critical start-up, safeguarding an asset valued at over $20 million.

Frequently Asked Questions (FAQ)

Q1: What is the most common commissioning error with Bently Nevada probe systems?

A: The most frequent issue we encounter is incorrect scaling between the protection monitor and the plant’s main control systems (DCS/PLC). The hardware may be perfect, but if the monitor’s output range is improperly configured to the input card’s scaling, the system will provide inaccurate, meaningless readings. This is why a full loop test is mandatory.

Q2: How does improper grounding affect the dynamic signal from a proximity probe?

A: Improper grounding or shielding introduces high-frequency noise and 50 Hz/60 Hz line frequency interference into the signal. This noise can mask actual, low-amplitude machine faults, such as early-stage bearing wear. A clean, stable DC bias with minimal AC noise (less than 1 mV peak-to-peak) when the machine is at rest is the gold standard for reliable signal quality.

Q3: Why is it crucial to check the linear range, even if the gap voltage is set correctly?

A: Setting the nominal gap voltage (e.g., 10 VDC) is insufficient. The linear range check confirms that the probe has sufficient travel margin in both directions before hitting the non-linear “clipping” points. If the probe is too close to a clipping point, a large vibration event could be severely distorted, leading to under-reporting of a dangerous vibration amplitude. This margin ensures accurate measurement of high vibration amplitudes.

Stop VFD Restarts: PowerFlex 700 Diagnostics for Automation
Industry News, NEWS

Fix PowerFlex 700 Power Cycling: Expert Troubleshooting Guide

Troubleshooting the PowerFlex 700: Stop the Power Cycle Madness

You have just installed a new variable frequency drive (VFD). However, your new Allen-Bradley PowerFlex 700 drive is stuck in a frustrating power-cycling loop. This happens even with no motor connected and the input voltage stable. This scenario is rare, but it is a critical issue in industrial automation setups. Before you assume a warranty return, experienced technicians suggest a series of focused diagnostic steps. This post, brought to you by Powergear X Automation, explores the common causes of this restart issue. We will guide you through effective troubleshooting to minimize downtime in your factory automation line.

Stop VFD Restarts: PowerFlex 700 Diagnostics for Automation

The Power Cycle Puzzle: Common Culprits in PowerFlex Drives

A PowerFlex 700 drive that instantly begins rebooting is not always defective. According to industry data, control systems failures of this type are often isolated to peripheral or interface components. Therefore, a complete drive replacement is frequently unnecessary. Understanding the component hierarchy is the first step toward efficient resolution.

Human Interface Module (HIM) Failure: A faulty HIM is a prime suspect. If this display unit or its internal logic fails, it can send continuous reset signals. This causes the drive to cycle even without load.

The T-Board Interface or Socket Damage: The T-Board serves as the crucial connection point for the HIM and any communication modules. A loose ribbon cable, corroded pins, or a cracked socket can break the continuous data flow. As a result, this connectivity failure triggers protective restarts.

Instability in the Internal Power Supply: The main power supply board may experience component drift or a failure in the smoothing capacitors. This can lead to unstable DC bus voltage, which is instantly interpreted as a fault by the main logic board.

Control Board Malfunction: A less common, yet serious, cause is a failure on the main control systems board itself. This could involve critical firmware memory or a logic gate failure.

Improper Wiring or Terminal Tightness: Loose connection points on the input terminals can lead to momentary voltage dips or spikes. The drive’s protective circuits will react instantly, causing the seemingly random reset.

Expert-Backed Steps for Fast Diagnosis

When dealing with a new PowerFlex 700 cycling, quick and methodical steps are key to diagnosing the true root cause. Electrical engineers in industrial automation recommend a non-invasive approach first.

Detach the HIM Module Immediately: Disconnecting the Human Interface Module is the most critical first step. If the power cycling stops, the fault is isolated to the HIM or the T-Board socket. Therefore, this simple action immediately halves the scope of the problem.

Swap for a Verified Working HIM: If available, substitute the suspect HIM with one from a known, working drive. If the PowerFlex 700 stabilizes, the original HIM is the defective component. However, if the cycling continues, the T-Board is the likely next candidate.

Utilize Rockwell Software Tools: Technicians should connect to the drive using an interface like the 1203-USB. Software like DriveExecutive or Connected Components Workbench (CCW) allows stable communication. If the drive allows reliable data reading, the core drive logic and power stage are probably sound. This data access helps pinpoint configuration issues or read the exact fault history.

A Detailed Inspection of Physical Connections: Power down and lock out the system before any physical check. Carefully inspect the T-Board socket and surrounding connection points. Look for bent pins, debris, or oxidation that suggests a poor electrical connection. In addition, ensure the input power terminals are torqued to the manufacturer’s specification.

Industry Insight: Many field engineers report that over 40% of initial drive instability issues are resolved by simply addressing loose terminal blocks or minor component seating issues.

Author’s Viewpoint: Minimizing Downtime and System Integrity

The introduction of modern VFDs like the PowerFlex 700 into PLC and DCS environments is critical. Their reliable function underpins the efficiency of modern manufacturing. This is the opinion of Powergear X Automation. We find that proper initial staging is the best defense against these start-up errors.

Bench Test Best Practice: Always power up the VFD on a test bench before final installation into the cabinet. This simple step validates the drive’s core function. It eliminates external wiring as a variable.

The Value of Spares: Maintaining a small stock of critical spare parts, particularly HIMs and I/O boards, is essential. Swapping a peripheral component is faster than a full drive replacement. This practice dramatically reduces Mean Time To Repair (MTTR).

We advocate for buying certified, pre-tested components. Each PowerFlex 700 we supply is thoroughly inspected by our in-house technicians. We back every unit with a 2-year warranty for full assurance.

When a Warranty Claim Becomes Necessary

If the drive continues to cycle after removing the HIM, checking the T-Board, and verifying all input voltages, the core unit is likely defective. Therefore, this final determination mandates initiating a Return Material Authorization (RMA) process.

System Integrity Checklist

Voltage Verified: Input voltage confirmed stable and within the ±10% tolerance.

Peripherals Removed: HIM and any communication modules are detached.

Terminals Secure: All power and control terminals are securely tightened.

No Fault Log: The drive cannot maintain power long enough to log a clear, persistent fault.

Document every troubleshooting step clearly before contacting your supplier. This documentation accelerates the warranty process.

Frequently Asked Questions (FAQ)

Q1: How can I check for a T-Board failure without a spare T-Board?

A: A definitive check without a spare is difficult. However, after removing the HIM, if the drive still cycles, the problem is deeper. If you can establish a stable serial connection using CCW but the drive remains unstable, the T-Board’s interface to the main board is often the issue. Look closely for physical damage or loose screws holding the T-Board in place.

Q2: Will a parameter conflict cause a new PowerFlex 700 to power cycle?

A: Yes, it is possible but less common than a hardware fault. If a default parameter setting conflicts severely with the actual installation (e.g., motor parameters outside the drive’s capability), the drive’s pre-boot check can trigger an immediate fault. This can look like a reset. Try using the software to perform a factory reset to eliminate this possibility before assuming a hardware failure.

Q3: What kind of physical damage should I look for on the control board?

A: Look for signs of overheating, such as discolored components or a burnt smell. Pay close attention to the electrolytic capacitors—if they appear bulging or leaking fluid, they have failed. This is a common indicator of a power supply or filtering issue that will certainly cause unstable cycling.

Smart Motor Controllers: The Future of Industrial Automation
Industry News, NEWS

Smart Motor Controllers: The Future of Industrial Automation

Smart Motor Controllers: The Strategic Shift for Modern Industrial Automation

The decision between using a smart motor controller and a traditional starter is far more than a simple technological upgrade; it is a strategic choice impacting facility uptime, energy efficiency, and long-term operating costs. Traditional motor starters are fundamentally simple devices that only handle starting and stopping the motor. However, smart motor controllers introduce advanced functionalities that deliver greater control, deeper insights, and significant efficiency improvements. From real-time diagnostics to remote firmware capabilities, these devices are fundamentally changing how manufacturers approach motor asset management. Let’s examine the decisive advantages and understand why forward-thinking facilities are now making this critical transition in industrial automation.

Smart Motor Controllers: The Future of Industrial Automation

Remote Updates Ensure System Agility and Security

Traditional starters are inherently static. Once installed, they cannot adapt to evolving operational demands or emerging security threats. Any necessary upgrade or fix requires a physical intervention, often leading to costly downtime or even complete unit replacement. Smart motor controllers, conversely, embrace dynamic adaptation. Drives like the Allen-Bradley PowerFlex 755T, Schneider Electric Altivar Process, and Danfoss FC 302 support Over-the-Air (OTA) firmware updates. This capability keeps your control systems current with the newest features, essential security patches, and performance enhancements—all without needing a technician onsite.

Faster Adaptation: Quickly respond to new regulatory or production requirements.

Reduced Maintenance: Minimize costs associated with manual service calls.

Continuous Improvement: Consistently enhance energy efficiency and control capabilities.

Commentary from Powergear X Automation: We consistently see remote update capability as a major differentiator. For busy plants with complex control systems like PLC or DCS, updating drives without interrupting production offers massive operational savings.

Proactive Voltage Monitoring Extends Motor Lifespan

Unexpected power quality issues, such as sharp voltage fluctuations or phase imbalances, pose a significant risk to industrial motors. Traditional starters offer no real-time protection, leaving valuable motor assets vulnerable to catastrophic failure. Smart controllers, by contrast, actively and continuously monitor voltage thresholds. If the system detects a deviation from nominal parameters, it initiates an automatic, protective response. This proactive defense mechanism can trigger a controlled load shedding, an immediate but safe motor shutdown, or an operator alert. Drives such as the Siemens SINAMICS G120, ABB ACS580, and Schneider Altivar 71 even allow operators to customize precise trip points based on their specific application needs. As a result, this feature not only extends the motor’s functional lifespan but also dramatically improves the stability of the entire factory automation system, especially in unstable utility environments.

Electrical Parameter Monitoring for Predictive Maintenance

A smart motor controller functions as the motor’s dedicated health monitor, providing deep, actionable data. Unlike standard starters, which provide zero operational feedback, smart controllers meticulously track and log key parameters. They measure essential metrics, including:

Voltage, current, and true power consumption

Frequency, power factor, and load trends

Energy usage over time

This constant data stream is foundational for effective predictive maintenance. Teams can analyze real-world data to identify potential motor fatigue or inefficiencies. For example, drives like the ABB ACS880 and Schneider Altivar Process feature integrated metering tools and historical data logs. Therefore, maintenance teams can identify energy waste or impending overloads before they escalate into disruptive and costly shutdowns.

Adaptive Control Drives Superior Energy Efficiency

Traditional starters operate using fixed, conservative parameters. Whether a motor is lightly loaded or operating at full capacity, it receives the same fixed voltage and speed setting. This results in excessive mechanical wear, wasted energy, and a shortened lifespan. Smart motor controllers utilize sophisticated adaptive control algorithms to dynamically adjust voltage, speed, and torque in real-time. They continuously evaluate dynamic factors like:

Instantaneous load variation

Ambient operational temperature

Precise process flow requirements

The outcome is exceptionally smooth operation, reduced mechanical stress on the motor, and demonstrably lower electricity expenses. Noteworthy examples of this technology include: Danfoss VLT FC 302 (for precision efficiency using dynamic flux control) and Allen-Bradley PowerFlex 755T (for intelligent speed/torque control across variable conditions). This is a key principle of modern industrial automation.

Seamless Industrial Communication for Connected Operations

Smart motor controllers are deliberately designed for the connected manufacturing environment. They communicate using standard industrial languages, facilitating direct integration into your wider DCS or PLC framework. Common protocols supported include:

Ethernet/IP

PROFINET

Modbus TCP

This connectivity allows controllers to feed vital, real-time insights—from motor health status to immediate energy consumption data—directly into your SCADA, HMI, or Manufacturing Execution System (MES). In contrast, traditional starters operate in informational darkness. They have no network connection, provide no feedback, and offer no integration into automated systems. Devices like the Siemens SINAMICS G120 and PowerFlex 700 series enable powerful features like automatic load balancing and predictive alerts, which are non-negotiable for today’s data-centric factories.

Fault Logging Simplifies Troubleshooting and Maintenance

Troubleshooting a failure related to a traditional starter is often a frustrating process of guesswork and delayed reaction. The issue is usually only discovered after it has caused a major operational fault or physical damage. Smart motor controllers eliminate this reactive maintenance trap. They feature robust, integrated diagnostic capabilities, including:

Automatic and time-stamped fault logging

Detailed event history and trend recording

Built-in self-diagnostics

This data makes identifying and diagnosing recurring issues significantly faster and more accurate. Furthermore, the logged history can be crucial for verifying warranty claims or supporting the scheduling of truly proactive, condition-based maintenance. As a result, operations experience fewer unexpected breakdowns and spend less time on costly reactive repairs.

The Strategic ROI: Why Smart is the New Standard

Adopting smart motor controllers delivers a clear Return on Investment (ROI). These devices are essential for future-proofing your operations because they:

Protect assets from damaging electrical faults.

Cut energy consumption through dynamic, adaptive control.

Simplify maintenance with deep, real-time diagnostic data.

Enable remote management via network-enabled firmware updates.

Extend the useful life of your motor fleet.

Author’s Comment: The shift is driven by economics. While the initial cost is higher, the total cost of ownership (TCO) for a smart controller is lower over a 5-year period due to energy savings and massive reduction in unplanned downtime. According to a MarketsandMarkets report, the global motor control center market is moving toward smart solutions, validating this strategic direction.

Application Scenario: Pump and Fan Systems

Consider a water treatment facility using a large pump system (a typical industrial automation application).

Traditional Starter: The pump runs constantly at 100% speed, even when only 60% flow is needed, wasting significant energy and causing unnecessary wear on mechanical seals.

Smart Motor Controller (e.g., Danfoss VLT): The drive uses a PID loop based on the pressure sensor feedback. It automatically and smoothly ramps the pump speed up or down to precisely match the current flow demand. This dynamic adjustment can lead to a 20-40% reduction in electricity consumption and drastically extends the Mean Time Between Failures (MTBF) for the pump system components.

Frequently Asked Questions (FAQ)

Q1: How much time and money can I realistically save by switching from a starter to a smart drive?

A: The savings are typically two-fold: energy and maintenance. The US Department of Energy often cites that Variable Frequency Drives (VFDs), a type of smart controller, can save 20-50% of the energy consumed by centrifugal pumps and fans by running them slower when full capacity isn’t needed. Moreover, the predictive maintenance data drastically reduces reactive repair costs and unexpected production losses, which can often be 5-10 times the cost of the repair itself.

Q2: Will integrating a smart motor controller complicate my existing PLC or DCS programming?

A: Generally, no. While traditional starters use basic hardwired I/O, smart controllers use industrial Ethernet (like PROFINET or Ethernet/IP). Modern PLC and DCS systems have pre-built Add-On Instructions (AOIs) or function blocks for major drive brands (Allen-Bradley, Siemens, Schneider). This simplifies the programming process and allows you to access hundreds of diagnostic parameters with just a few data tags, which is far simpler than managing dozens of physical wires.

Q3: Is it better to upgrade an old motor or install a smart controller with my existing motor?

A: If your motor is in good condition, you can typically install a smart motor controller (VFD) immediately for instant efficiency gains. However, for maximum efficiency and longevity, especially with drives, we recommend upgrading to an Inverter Duty (NEMA Premium Efficiency) motor. These newer motors are thermally and electrically designed to handle the high-frequency switching and harmonics produced by the smart controller, ensuring the longest lifespan for both components.

Need a Recommendation?

If your facility is still reliant on traditional motor starters, the time to upgrade is now. We stock and support top-tier smart motor controllers from every major brand—Allen-Bradley, Siemens, Schneider Electric, ABB, and more. Our experts can help you select the ideal drive tailored to your specific application and system architecture.

Bently Nevada 3500/22M TDI Evaluation for Industrial Automation
Industry News, NEWS

Bently Nevada 3500/22M TDI Evaluation for Industrial Automation

Evaluating Your Bently Nevada 3500/22M TDI: Replacement vs. Reconfiguration in Industrial Automation

The Bently Nevada 3500 Machinery Protection System is a cornerstone of critical asset monitoring in heavy industry. At its core, the 3500/22M Transient Data Interface (TDI) acts as the central nervous system. This module is vital for configuration management, transient data capture, and communication within complex industrial automation and control systems. When operational issues arise, maintenance engineers face a crucial decision: Is this a simple fix via reconfiguration, or does the TDI require a full replacement? Making the wrong call leads to unnecessary downtime and increased costs, impacting overall factory automation efficiency.

Bently Nevada 3500/22M TDI Evaluation for Industrial Automation

The Critical Role of the 3500/22M TDI in Machine Protection

The TDI is more than a simple gateway; it is the data traffic controller for the entire rack. Its primary duties include storing the rack configuration, managing high-speed data transfer to System 1 condition monitoring software, and ensuring reliable Modbus TCP/IP and Ethernet communications. Moreover, it coordinates module diagnostics and provides essential time synchronization. Because its function is so pervasive, any error in this module directly compromises the integrity of machine protection. Therefore, a structured diagnostic approach is essential for maintaining reliable PLC and DCS integration environments.

Symptoms Suggesting a Simple Reconfiguration is Sufficient

  • Many common TDI issues stem from software glitches or data integrity problems, not hardware failure. When you observe these symptoms, a simple configuration reload or firmware update is typically the most effective solution:
  • Intermittent Communication Failure: The system may experience occasional Modbus drops or System 1 connection losses. This often presents as data timeout warnings. Crucially, the TDI’s front-panel LEDs remain green, and no hard fault lights appear.
  • Configuration Integrity Errors: Look for “Configuration Not Valid” messages or issues during upload/download with the 3500 Configuration Software. These errors usually follow an interrupted transfer or an improper configuration change.
  • Firmware Mismatch and Corruption: If the TDI was recently updated, or if rack modules and the TDI have mismatched firmware versions, communication warnings are common. Reloading the firmware often resolves these versioning inconsistencies.
  • Temporary Recovery After Power Cycling: If cycling the rack power temporarily restores full operation, the underlying hardware is generally sound. The issue is likely a software lock-up or memory error, a scenario often remedied by a re-initialization process.

Clear Indicators That a TDI Replacement is Necessary

Hardware failures are definitive and cannot be resolved with software fixes. If your TDI exhibits the following signs, prepare for a full module replacement to restore system functionality:

Hard Fault Indicators on the Module: The presence of a continuously illuminated red “Module Fault” LED, or a red “OK” LED, signals a severe internal component failure. Also, if all LEDs remain off after powering the rack, internal power supply or circuit damage is suspected.

Irrecoverable Communication Hardware Failure: This means the Ethernet port is physically non-functional. The link lights on both ports will not illuminate, even after verifying cables and network switches are working. The module is detected, but it cannot physically transmit or receive data.

Failure Persistence After Full Diagnostic Sequence: If you have attempted a firmware reload, a configuration reload, and a rack power cycle, and the module still fails system diagnostics, hardware degradation is highly likely.

Thermal or Power-Related Failures: Visible signs such as a burnt smell, PCB discoloration, excessive overheating, or random, continuous resets despite stable power indicate a failure in the internal voltage regulator circuitry. According to industry data, aging voltage regulators are a common failure point for modules over ten years old.

A Field-Proven 5-Step Diagnostic Workflow

Engineers at Powergear X Automation recommend this structured approach to swiftly differentiate between software and hardware problems:

  • Check the TDI’s Front-Panel LEDs:
  • Green: Proceed with configuration and firmware checks.
  • Red or Off: Halt software attempts; prepare for replacement.
  • Verify Communication Recovery Attempts: Try swapping cables and connecting directly with a laptop. If the link restores, the issue is external (network).
  • Reload the Configuration File: Upload the current file and immediately re-download it back to the rack. This corrects common configuration inconsistencies that lead to instability.
  • Update or Reinstall the Firmware: A fresh firmware installation can resolve subtle memory or instruction set corruption.
  • Test System After Rack Power Cycle: If the module fails diagnostics immediately after the rack is fully powered up and re-initialized, the fault is almost certainly hardware-based.

Author’s Insight: When Proactive Replacement is Smart

While cost is always a factor, a proactive replacement can be the better long-term strategy for critical assets. The 3500/22M TDI plays an active role in transient data capture, which is essential for detailed diagnostics. If your TDI has served for over a decade, or if your site experiences repeated, inexplicable rack-wide communication issues, consider an upgrade. IEEE reliability standards often suggest a Mean Time Between Failures (MTBF) reduction after ten years of continuous operation, especially in harsh environments. The cost of a spare module is negligible compared to the financial impact of unplanned shutdown of a critical turbomachinery train. Maintaining a spare TDI in inventory is a standard best practice in DCS and PLC environments.

Technical Best Practice Checkpoints

  • Firmware Alignment: Ensure the TDI firmware version is fully compatible with all installed I/O modules (e.g., 3500/42M).
  • Voltage Stability: Use a multimeter to verify stable rack power supply output if random resets occur.
  • Direct Connection: When troubleshooting, always bypass network infrastructure by connecting directly to the TDI Ethernet port for a reliable communication test.
  • Transient Buffer: Unreliable transient capture in System 1 is a strong indicator of an aging TDI communication processor.

Case Study: Addressing Chronic Data Loss

A petrochemical plant running an older 3500 rack began experiencing intermittent gaps in vibration data sent to System 1. The module lights were all green, suggesting a configuration problem. However, multiple configuration and firmware reloads failed to solve the chronic data loss, indicating the communication issues were not being corrected at the software level. The engineers decided to replace the 3500/22M TDI. Post-replacement, the data stream became instantly stable, confirming a low-level hardware component—likely the Ethernet PHY chip—was degrading and causing packet loss without triggering a hard fault. This averted a potential loss of critical machine data.

Frequently Asked Questions (FAQ)

Q1: How can I definitively rule out the network before blaming the TDI for communication issues?

The simplest way is to connect a laptop with the 3500 Configuration Software directly to the TDI’s Ethernet port using a cross-over or straight-through cable (depending on the model). If you achieve a stable, continuous connection and can communicate with the module, the network infrastructure (switch, patch panel, cable run) is the source of the problem. If the direct link is unstable, the TDI hardware is the suspect.

Q2: My TDI is over 12 years old but appears to be working. Should I replace it anyway?

While continuous operation is a good sign, an older module, especially one that handles transient data, is operating on borrowed time. Industry experience shows that passive components (capacitors, resistors) degrade over time, affecting signal integrity and power regulation. A proactive replacement prevents an unplanned failure, which is almost always more expensive than a scheduled replacement. Keep the old module as a low-priority, non-critical spare or consider it for immediate disposal.

Q3: What’s the most common configuration error that mimics a TDI hardware failure?

The most common and confusing error is a version mismatch between the rack configuration file and the firmware loaded on the TDI. If the file was created with an older software version or the rack I/O modules were updated but the TDI wasn’t, the TDI will often become unstable, dropping communication. Always ensure your configuration software, rack firmware, and System 1 version are all compatible before concluding a hardware failure.

5-Step Servo Drive Troubleshooting Guide
Industry News, NEWS

Servo Drive Repair vs. Replacement in Industrial Automation

Overview

Servo drives are the unsung heroes of precision manufacturing, providing the speed and accuracy necessary for robotics, CNC machinery, and high-speed packaging lines.When a drive malfunctions, production grinds to a halt quickly. Whether your facility relies on a Mitsubishi MR-J2S, Yaskawa SGDH, or FANUC A06B series drive, fast and effective troubleshooting is crucial. A systematic approach determines the difference between a fleeting inconvenience and a costly, extended shutdown. This expert guide walks you through a structured, five-step diagnostic process. We highlight common brand-specific failure signatures. Finally, we provide clear criteria for deciding whether to repair, replace, or escalate the issue within your factory automation system.

Step 1: Systematically Identify Failure Symptoms

Before reaching for a multimeter or a manual, you must gather detailed, observable symptoms. Simply noting “drive fault” is insufficient for accurate diagnostics. Specificity saves time.

Observable Indicators:

A specific alarm or fault code appears on the drive’s display.

The motor is completely unresponsive or exhibits erratic, jittering movement.

Motion unexpectedly stops mid-cycle, disrupting the PLC sequence.

A distinct burnt odor is present, or the drive housing feels excessively hot.

The drive shows no display and has no power indicator lights.

Pro Tip from the Field: Document the exact drive model number and the displayed alarm code immediately. Moreover, record the system’s behavior just before the failure. This information is vital for accurately isolating the root cause and defining the next course of action.

Step 2: Eliminate External Factors First (Power and Wiring)

In industrial automation, internal drive failures account for fewer issues than external problems. Before investigating complex fault codes, eliminate the simplest, most common external causes first.

Fundamental Electrical Checks:

Verify Input Voltage: Use a true RMS multimeter to confirm the drive receives the correct input voltage at the terminals.

Inspect Connections: Check all cables and terminals for loose connections, corrosion, or signs of arcing and heat damage.

Check for Shorts/Ground Faults: A short circuit in the motor winding or cabling often triggers immediate drive overcurrent alarms.

Powergear X Automation Insight: We estimate that over 40% of all reported “drive faults” are resolved by simply correcting power or wiring issues. For instance, on a Yaskawa SGDH drive, an A.C. alarm frequently points to a shorted output or incorrect motor wiring. Therefore, always confirm good grounding, especially on older legacy systems like the Mitsubishi MR-J2S, after any maintenance.

5-Step Servo Drive Troubleshooting Guide

Step 3: Interpret Drive Alarm Codes and Fault History

Servo drives incorporate sophisticated self-diagnostic capabilities. The alarm or fault code displayed on the panel is your most important clue. Different brands use distinct codes for similar failures.

Key Fault Codes by Brand:

Mitsubishi MR-J2S:

  • AL.37: Indicates Overcurrent during deceleration—often a mechanical issue or tuning problem.
  • AL.33: Points to an Encoder error—a feedback problem.

No Display: Often suggests a blown fuse or power board failure.

Yaskawa SGDH:

  • A.C.: Output short circuit—check motor/cable integrity.
  • A.E.: Overvoltage—frequently caused by poor regeneration handling.

Solid Red LED: Indicates a severe internal hardware failure.

FANUC A06B:

  • AL-1: Overcurrent—a common indication of a shorted load or motor.
  • AL-3: Regenerative error—the drive cannot dissipate energy effectively.
  • No LED: Suggests an issue with the control or power board.

Expert Tip: Many modern drives and even some legacy control systems store a fault history log. Reviewing this log helps identify patterns. In addition, recurring errors suggest environmental factors like heat, vibration, or unstable input power.

Step 4: Isolate the Problem to the Motor or the Drive

The servo drive and motor operate as a synchronized, closed-loop system. A fault originating in the motor (e.g., a shorted coil or a damaged encoder) will cause the drive to trip, masking the true source.

Motor Testing Methods:

  • Known-Good Swap: The quickest diagnostic method is temporarily swapping the suspect motor with a functional, known-good spare unit.
  • Electrical Verification: Perform a Megger test to check for shorts to ground and use a multimeter to confirm equal resistance across all motor phases.

Brand-Specific Motor Failure Notes:

  • MR-J2S: Encoder feedback problems are prevalent. Always check the integrity of the encoder cable and connector pins.
  • SGDH: Persistent A.E. or A.C. alarms often require checking for open or shorted motor windings.
  • A06B: Motors with shorts to the ground are a leading cause of damage to the power output section of the drive.

Solution Scenario: If on-site motor testing is impractical, specialized facilities offer bench testing and joint drive-motor evaluations to diagnose system interaction issues accurately before further equipment is damaged.

Step 5: Make the Informed Decision: Repair, Replace, or Retest

Downtime is costly. Your final decision—repair or replace—must balance cost-effectiveness against required recovery speed. Statista data shows that the cost of unplanned downtime in manufacturing can exceed $10,000 per hour.

ActionJustification
Repair the DriveThe failure is clearly internal (e.g., blown component). The model is obsolete or legacy (like MR-J2S) and expensive to replace. A cost-effective fix is needed, and you can tolerate a few days of turnaround time. You must retain the original application settings or custom wiring.
Replace the DriveThe same fault has recurred multiple times. There is visible, catastrophic damage (burned components, cracked boards). Immediate recovery is mandatory to prevent production line delays. You are actively upgrading the control systems to newer, supported models.
Retest or EscalateThe fault is intermittent or only happens under high load. You have replaced the drive, but the problem persists. You strongly suspect external factors like EMI or grounding issues.

Frequently Asked Questions (FAQ)

Q1: What is the significance of the “No Display” fault on a Mitsubishi MR-J2S drive, and what should I check first?

A: A “No Display” on the MR-J2S typically signifies that the low-voltage control power supply on the drive’s power board has failed. Before concluding the drive needs repair, always check the incoming control voltage fuse. If the fuse is intact, the failure is usually internal (e.g., a power supply circuit failure), requiring the unit to be sent to a dedicated repair center.

Q2: My Yaskawa SGDH drive trips on an “A.E.” (Overvoltage) alarm only when the machine decelerates quickly. Why is this happening?

A: This is a classic symptom of a failure in the regenerative circuit, which handles the energy fed back from the motor during deceleration. The drive is unable to dissipate this energy, causing the DC bus voltage to spike. The issue could be a faulty internal braking transistor, a failed external braking resistor unit (if used), or incorrect wiring to the external resistor. Check the resistor’s continuity and connections, as this is a more common point of failure than the drive’s internal components.

Q3: We have recurring encoder errors (AL.33 on MR-J2S) after a major machine vibration event. Can I fix this without replacing the drive or motor?

A: Recurring encoder errors, especially after a physical shock, suggest mechanical damage or a connection problem, not necessarily a motor coil failure. First, meticulously check the encoder cable and its connector at both the motor and the drive end for any bent pins or abrasions in the shielding. If the error persists, the encoder head or disk inside the motor is likely misaligned or damaged. Replacing the motor’s encoder unit or the entire motor is usually the required course of action, as internal encoder repair on-site is difficult.

Seamlessly Connect 3500/22M TDI to Your Industrial Control System

The Critical Role of the 3500/22M in Plant Reliability

The Bently Nevada 3500/22M Transient Data Interface (TDI) is a cornerstone of machinery protection and condition monitoring for critical rotating assets like steam turbines, gas turbines, compressors, and large motors. The module excels at capturing high-resolution dynamic data and transmitting it to the proprietary System 1 platform. However, modern industrial automation demands a higher level of integration: directly linking the 3500/22M with the plant’s distributed control system (DCS) or supervisory control and data acquisition (SCADA) layer. This connection is not merely a convenience; it is an operational imperative for integrated plant management.

Seamlessly Connect 3500/22M TDI to Your Industrial Control System

Bridging the Gap Between Protection and Control

Integrating the monitoring system into the main control systems ensures that vital event data, real-time vibration levels, alarm statuses, and machine health flags become instantly accessible to control room operators. This accelerates the response to anomalies. Conversely, a lack of integration creates operational silos. Engineering teams frequently wrestle with technical obstacles, including signal incompatibility, mismatched communication protocols, data latency, and evolving cybersecurity requirements. This guide offers proven, practical methodologies to achieve efficient and reliable integration of the 3500/22M with your chosen DCS/SCADA platform.

  • Powergear X Automation Comment: Factory automation is moving towards complete data convergence. The days of separate, isolated monitoring systems are ending. Seamless data flow from the protection layer to the PLC and DCS is now a requirement for operational excellence.

Why Integration Drives Operational Resilience

Integrating the 3500/22M delivers measurable engineering and operational value. It centralizes visibility of machine condition, allowing operators to make timely decisions without navigating multiple proprietary software interfaces. This convergence significantly improves alarm and trip management, enabling a faster response to critical events. Moreover, by contextualizing vibration data with process variables (like pressure and temperature), the foundation for true predictive maintenance is established. Complying with standards such as API 670 for machinery protection also necessitates robust, auditable data integration, directly contributing to reduced unplanned downtime.

BenefitEngineering Value
Unified Machine Condition ViewFaster operator action; eliminating system switching.
Improved Event ResponseRapid alarm acknowledgment and trip management.
Data ContextualizationEnables actionable insights for predictive maintenance strategies.
Compliance & AuditabilitySupports industry standards and regulatory requirements.
Minimized Unplanned DowntimeEarlier detection of minor machine anomalies.

Understanding the Integration Architecture and Protocol Options

The 3500/22M module supports several standard communication paths essential for connecting to supervisory control systems. These typically include Modbus RTU (serial) and Modbus TCP (Ethernet). OPC via System 1 is also an option for high-level diagnostics. The standard architecture involves the 3500/22M communicating through a rack interface, over a network switch, and then to the DCS/SCADA server. Crucially, the TDI module handles the real-time status and register data using Modbus, while System 1 is dedicated to detailed waveform and advanced diagnostic analysis.

Selecting the Optimal Communication Protocol

  • Choosing the right protocol is the first critical decision.
  • Modbus TCP (Recommended for Modern Systems): This is the preferred choice for modern DCS and SCADA environments. It offers superior throughput and simplifies the mapping and scaling of data points. Use Modbus TCP if you have a stable Ethernet network, require multiple client access, and have implemented appropriate cybersecurity controls.
  • Modbus RTU (RS-485 Serial): This robust protocol remains relevant for noisy environments or where legacy SCADA masters only support serial inputs. Use RTU if network infrastructure is limited or for simple, point-to-point connections.
  • OPC via System 1 (For Analytics, Not Protection): OPC (most commonly OPC UA today) is ideal for connecting to plant historians and asset performance management (APM) systems. However, it should not be the primary link for protection alarms due to potential added software layers and latency. It is best used for long-term trending analytics and condition-based maintenance data.

A Structured Approach to Engineering Configuration

Successful integration follows a disciplined four-step process.

Step 1 — Defining the Necessary Data Signals

Determine precisely which data points must flow to the DCS/SCADA. This typically includes primary vibration levels (peak/RMS), Keyphasor speed, alarm flags, event statuses, and diagnostic parameters like probe gaps. A key engineering tip: Avoid sending high-resolution transient or waveform data; the SCADA layer does not require or effectively process this detailed information.

Step 2 — Configuring Modbus Mapping in the 3500 Rack

The TDI module requires meticulous configuration. Key tasks include assigning sequential register addresses, selecting the correct data type (e.g., FLOAT32), and accurately setting the byte order (Endianness). Using a test Modbus client to validate the channel-to-register map before final deployment is essential. Powergear X Automation recommends standardizing naming conventions early, such as “TBN_H2_VIB_RMS,” for maintainability.

Step 3 — Configuring the DCS/SCADA Endpoint

The required steps vary based on the vendor (Emerson DeltaV, Yokogawa, Honeywell, ABB, Siemens PCS7, etc.). You must create the Modbus device definition, configure the communication channel, and set an optimal polling rate (typically between 500 ms and 2000 ms). It is critical to apply scaling factors and validation routines consistent with the 3500 configuration.

Step 4 — Rigorous Testing and Validation

Thorough testing during the commissioning phase is non-negotiable.

  • Communication Handshake Test: Confirm Modbus client/server stability.
  • Value Trending Test: Verify stable, real-time signal trending with zero dropouts.
  • Alarm Simulation Test: Manually trigger alarms to ensure the SCADA receives them within acceptable latency bounds.
  • Failover Test: Ensure the integration does not compromise the integrity of the primary protection layer.

Troubleshooting Common Integration Challenges

ProblemRoot CauseSolution
Incorrect Data ScalingMisaligned engineering units (e.g., mm/s vs. in/s).Verify and align scaling in both TDI and SCADA configurations.
Byte Order MismatchEndianness incompatibility (Big-Endian vs. Little-Endian).Adjust the Modbus word/byte swap mode on the SCADA master.
Delayed AlarmsPolling rate is too slow for event-based data.Optimize the SCADA polling rate or use dedicated alarm status bits.
Data Dropouts on SerialElectrical noise, poor grounding, or improper cable routing.Use shielded twisted pair cable and ensure correct grounding practices.

Prioritizing Cybersecurity Best Practices

Because the 3500 system is intrinsically linked to critical protection logic, cybersecurity cannot be an afterthought. This system is part of your overall industrial automation network, and protecting it is paramount.

VLAN Segregation: Use Virtual Local Area Networks (VLANs) to separate condition monitoring and protection traffic from the general business network.

Disable Unused Ports: Turn off all unused physical ports and unnecessary services on network devices and the TDI module.

Access Control: Enforce strong password policies and apply access control only to authorized configuration personnel.

Documentation: Maintain up-to-date documentation of network topology and rigorous change control procedures for all configuration changes.

Application Scenario: Integrating Gas Turbine Health

In a major combined cycle power plant, the integration of the Bently Nevada 3500/22M on the main Gas Turbine (GT) provides real-time health metrics to the plant’s Siemens PCS7 DCS. This setup allows the GT’s vibration and thrust position data to be displayed alongside the gas turbine’s combustion and steam parameters. As a result, operators can observe a slight, sustained increase in axial position (thrust) that would otherwise be missed if they only relied on the proprietary monitoring system. The DCS triggers an intermediate alarm, prompting an inspection well before the vibration level reaches the API 670 trip setpoint. This is a clear demonstration of how integration shifts the paradigm from protection to true predictive capability.

Frequently Asked Questions (FAQ)

Q1: How does the polling rate impact my data integrity and system performance?

A: A slower polling rate (e.g., > 3000 ms) can lead to stale data in the DCS, meaning you won’t see critical changes as quickly. However, a rate that is too fast (e.g., < 200 ms) can overload the Modbus server in the 3500/22M or congest the network. Based on our experience, a balanced rate between 500 ms and 2000 ms generally provides a good compromise between responsiveness and network stability.

Q2: Should I use a dedicated fiber optic link for the Modbus TCP connection?

A: While copper Ethernet is usually sufficient for short runs, a dedicated fiber optic link is highly recommended in environments with significant electromagnetic interference (EMI), such as near large motor control centers or variable frequency drives. This provides superior noise immunity and can prevent intermittent data dropouts, which are particularly frustrating to troubleshoot.

Q3: We only use System 1 for analysis. Why should we bother with the DCS integration?

A: System 1 is optimized for diagnostic analysis and long-term trending (data scientists and reliability engineers). DCS integration is for real-time situational awareness (control room operators). Operators are trained to manage the entire process from the DCS console. Forcing them to switch applications delays response time, increases the cognitive load, and introduces the risk of missing a critical process context. Integrating the data ensures the machine health is part of the operational safety and control loop.

Conclusion

Integrating the Bently Nevada 3500/22M TDI with modern DCS/SCADA systems transforms machine protection into a comprehensive component of industrial automation. This convergence provides real-time situational awareness, enhances operational reliability, and guarantees a quicker, more informed response to machinery anomalies. By adhering to best practices in protocol selection, structured Modbus mapping, rigorous cybersecurity measures, and disciplined testing, the integration will become a stable, scalable, and maintainable element of your plant’s ecosystem. This strategic approach supports both critical machinery protection and advanced predictive maintenance initiatives, ultimately aligning with standards of operational excellence.

Siemens 6SL3100 SINAMICS S120 Line Module: Selection and Troubleshooting
Industry News, NEWS

Siemens 6SL3100 SINAMICS S120 Line Module: Selection and Troubleshooting

The Siemens 6SL3100 line module is the unsung hero of the SINAMICS S120 drive system.

This component serves as the power heart, converting incoming AC mains power into the critical DC link voltage. The DC link then supplies power to all connected motor modules. Sizing the 6SL3100 correctly ensures peak performance, energy efficiency, and reliable uptime in any industrial automation setup. Mismanagement of this sizing decision, however, directly jeopardizes your entire production line.

Siemens 6SL3100 SINAMICS S120 Line Module: Selection and Troubleshooting

Powergear X Automation Commentary on 6SL3100 Selection

Selecting the right line module is a foundational decision in designing robust control systems. Our experience at Powergear X Automation shows that inadequate sizing is a leading cause of premature drive failure and unnecessary downtime. The 6SL3100 series offers versatility, from high-speed packaging machines to heavy-duty factory automation in metals processing. Making the right choice is essential for smooth, cost-effective production.

Understanding Regenerative vs. Non-Regenerative Architectures

The first step in selection is defining the system’s braking demand. This fundamental choice significantly impacts overall energy consumption and heat generation.

Non-Regenerative (Basic Line Modules): These simply convert AC to DC. They are the ideal choice for applications with stable loads and minimal braking or deceleration. Examples include continuous conveyors, simple pumps, and fans. They dissipate braking energy as heat, usually through external braking resistors.

Regenerative Line Modules: These sophisticated units return excess braking energy back to the plant’s mains grid. This dramatically reduces heat output and eliminates the need for large, costly external brake resistors. Regenerative technology is essential for high-dynamic applications. Consider them for robotics, frequent start/stop systems, metal forming, and critical winding/unwinding processes. MarketsandMarkets reports show regenerative drives significantly improve energy profiles in industrial settings.

Decoding the SINAMICS 6SL3100 Part Number

Navigating the ordering process requires understanding the specific part number structure. The 6SL3100 code is a comprehensive technical signature.

2AB0VariantSpecifies cooling method, hardware version, and design

Understanding this code ensures you order the exact module your PLC or DCS application requires. This attention to detail prevents costly misorders and project delays.

The Critical Selection Guide: Voltage, Power, and Cooling

Proper specification of the 6SL3100 minimizes operational risk and maximizes efficiency.

Key Technical Considerations:

Voltage Class: This must precisely match the incoming plant mains supply (e.g., 400 VAC or 480 VAC). Mismatching voltages will result in immediate system faults.

Power Rating: Calculate the combined maximum load of all motor modules connected to the common DC bus. Size the line module with a safety margin to handle this cumulative peak power demand.

Cooling Method: Standard cabinets utilize air-cooled modules. However, compact enclosures or harsh, dusty environments demand the use of liquid-cooled units for reliable heat dissipation.

Format Factor: Choose between Booksize (slim, vertical orientation) or Chassis (larger, high-power) formats to fit specific cabinet space and layout constraints.

Proactive Maintenance and Troubleshooting Techniques

Effective industrial automation relies on minimizing unexpected faults. Based on our field experience, the 6SL3100 series exhibits a few common, easily resolved fault codes.

Common 6SL3100 Faults & Solutions:

F3001 (Overvoltage): This often happens during rapid deceleration. The DC link voltage spikes because the line module cannot handle the excess energy.

Solution: For non-regenerative systems, ensure brake resistors are correctly sized. For high-dynamic systems, the lasting solution is upgrading to a regenerative line module.

F3002 (Undervoltage): This typically indicates an unstable mains supply or a loose electrical connection.

Solution: Verify the stability of the plant mains. Tighten all mains power lugs and check fuse or circuit breaker integrity.

F3003 (Overtemperature): This is a hardware issue, often caused by blocked ventilation paths or a failed internal fan.

Solution: Schedule quarterly cabinet cleaning to remove dust and debris. Verify that all fan health indicators are green during preventative maintenance.

Preventative Tips: Keep air paths clear, schedule firmware updates according to Siemens recommendations, and inspect all electrical connections during planned downtime.

Acquisition and Stocking Strategies for Uptime

High-value components like the 6SL3100 require intelligent procurement planning. Lead times can fluctuate, especially for high-power regenerative models.

Plan Ahead: Consult your supplier early. High-power or specialty 6SL3100 units may have extended lead times of several weeks or even months.

Critical Spares: For any critical production line, stocking one spare 6SL3100 is a highly recommended practice. The cost of a spare module is minimal compared to the loss of thousands of dollars per hour of unscheduled downtime.

Compatibility Check: Always cross-verify the voltage, power, cooling, and regeneration type against your existing S120 control systems configuration before finalizing an order.

Application Case Study: High-Dynamic Spindle Control

A textile company struggled with frequent brake resistor failures on its winding/unwinding station using a basic line module. The frequent stop/start cycles generated massive amounts of heat.

Solution Scenario:

We replaced the non-regenerative 6SL3100 with a regenerative model. This upgrade eliminated the need for the brake resistors entirely. The braking energy was efficiently fed back into the grid, resulting in:

30% reduction in cabinet cooling load.

Zero brake resistor-related failures.

A measurable decrease in monthly energy consumption.

This showcases the economic and operational value of selecting the correct regenerative technology.

Frequently Asked Questions (FAQ)

Q1: What is the main operational difference between a Basic Line Module (non-regenerative) and an Active Line Module (regenerative)?

The Basic Line Module is only a rectifier, converting AC to DC. An Active Line Module (ALM) uses IGBTs and advanced control to not only rectify power but also actively manage the DC link and return excess power (regeneration) to the grid, leading to better power quality and energy savings.

Q2: My S120 drive system keeps tripping on F3003 (Overtemperature) only during the summer months. What is the most likely non-module-related issue?

This is typically an environmental issue combined with system stress. Check if the cabinet air conditioner or heat exchanger is properly maintained and sized for the peak ambient temperature. Dust accumulation on cooling fins reduces heat exchange efficiency, causing the internal fan to run continuously and eventually fail, or simply be unable to handle the heat load.

Q3: We are integrating a new 6SL3100 module into an existing S120 system. What is one critical step an experienced technician should take before powering up the drive for the first time?

Beyond standard wiring checks, the technician must verify the firmware version of the new line module is compatible and aligned with the version running on the Central Control Unit (CU). DRIVE-CLiQ communication errors (F3004) often result from firmware mismatches, and a quick check and necessary update will prevent hours of frustrating troubleshooting.

Conclusion

The Siemens 6SL3100 line module is the power foundation of the SINAMICS S120 system. Specifying the correct voltage class, power rating, cooling, and regeneration technology is a direct investment in efficiency, lower operating costs, and maximizing system uptime.
