Webcast learning objectives: 

  • AC drives significantly reduce energy consumption 
  • Common applications for AC drives
  • Common methods of AC drive regulation

 

 

More info on the event is provided by CFE Media below:

Variable speed drives provide effective speed control of AC motors by manipulating voltage and frequency. Controlling the speed of a motor provides users with improved process control, reduced wear on machines, increased power factor and large energy savings.

The most significant energy savings can be achieved in applications with a variable torque load. Reducing a fan’s speed in a variable torque load application by 20% can achieve energy savings of 50%. Therefore, for most motion control applications, reducing motor speed is often the easiest way to get large energy savings.

AC drives significantly reduce energy consumption by varying the speed of the motor to precisely match the effort required for the application. To vary the speed of the motor dynamically, a closed-loop regulator that considers the measured output of a process is required. Common applications where this is used include pressure, level and temperature control. The most common method of regulation is the PID (Proportional-Integral-Derivative) control loop.

Case Study – From Old to New: Modifying a Legacy Dual Textile Spray Line into an Efficient Machine with Doubled Throughput

Posted on by Patty Davis

Heytex, a brand of the German-based Heytex Bramsche GmbH, is a global developer and manufacturer of high-quality technical textiles. Their portfolio includes sophisticated and unique products fabricated and engineered using complex textile technology, such as signage, banners, boats, sales, barriers, and other technical textile products for a variety of customers. Electronic Drives and Controls (EDC), a recognized leader in the design, upgrade, and service support of drive and PLC Systems, recently helped Heytex significantly improve industrial textile coatings equipment for a military customer and double their overall production capabilities. 

Problem

Heytex had previously purchased a used paint line machine at auction that consists of two parallel production lines sharing the same painting booth and oven sections which could run concurrently or separately. However, one of the lines (Line 2) sat idle for approximately three years before Heytex sought help improving its operability to produce spray-painted industrial camouflage textiles for a military customer. Parts from Line 2 were scavenged to keep Line 1 running.

Originally, Heytex would receive an AutoCAD file from their military customer that specified the geometry of the desired pattern to be painted by the machine. Each line has six drives: 3 VFDs for web handling and 3 servo drives to traverse the paint heads. The process begins by feeding industrial fabric through a conveyor from an unpainted fabric roll. Next, three spray heads move across the fabric in a coordinated fashion applying green, brown and black paint resulting in a specified camouflage pattern. The machine then dries the fabric in a tunnel oven and rolls it into a finished painted textile roll.  

As purchased, each section of the machine used a personal computer with an obsolete Windows XP operating system and a soft Allen Bradley Programmable Logic Controller (PLC) for the unwinding and painting of the fabric. Two physical Omron PLCs handled downstream control, one for the oven and conveying systems and another on the rewind section. A proprietary software run on the XP operating system utilized algorithms to control the paint from the spray heads and help to convert the customer’s CAD files into control commands, a very cumbersome process requiring much manual intervention.

Another problem impeding the retrofit plan was a tremendous lack of documentation and labeling. This coupled with obsolete controls, proprietary software and a burdensome workflow with no known support prompted Heytex to task EDC with improving the machine with an integrated hardware and software design.  

Solution

EDC’s approach was to streamline the control architecture ensuring that the PLC, drives and HMI were from the same manufacturer and would all be on the same communications network. Three disparate control programs were consolidated into one PLC, eliminating the need for a machine-based computer, soft PLC and monitor. The Siemens S7-1500 PLC and S120 drive platforms coupled with a 12-inch Comfort Panel were an excellent fit for this application. 

Siemens’ S120 Sinamics Smart line module and common DC-bussed drives provide energy saving load sharing across the six drives and is able to regen excess AC voltage back to the incoming power line. Line drives were previously controlled in a start/stop mode and could only run at other speeds by manually changing the internal drive parameters. The S120 system provided full speed control capabilities as commanded by the PLC over a ProfiNet network.

The S7-1500F failsafe PLC simplified safety component wiring, especially given that three new cable-operated switches (safety rope pulls) were installed at the Unwind Exit, Paint Booth Entry and Rewind, improving the overall safe operation of the line. All main control components communicated with the PLC over a single ProfiNet control network including six VFD and servo drives, two remote I/O hubs and a new 7” HMI located at the Rewind section.

In addition to the cable-operated switches, other mechanical upgrades included a specially designed tension control system for the Unwind, adapters to couple new servo motors to existing spray head linear actuators, a line speed encoder at the oven exit and a linear position transducer for accumulator feedback. The EDC Field Installation Team installed and wired the new elements on Line 2 and ensured their proper functionality.

As previously mentioned, EDC consolidated all PLC logic into one CPU that closely communicates with the new HMI and S120 drive system. A user-friendly HMI screen and a recipe system were incorporated to improve the operator’s experience running the line. An offline program to convert the customer’s CAD files to data the PLC could use for proper control of the spray heads was a crucial part of the upgrade. EDC’s Project Engineer wrote an open-source Java script/HTML interface that could be modified by anyone with those computer language skills, eliminating the proprietary nature of the previous software incarnation.

Another key element of EDC’s retrofit is their documentation. A full set of wiring schematics was created that included reference for all components, wire numbers and a terminal plan. The customer was given a physical binder with hard copies of the drawings and digital copies of the control programs, the CAD conversion program and component manuals. A Tosibox remote access module was installed and connected to the machine’s control network. When connected to the internet, this device provides an ultra-secure VPN tunnel for remote monitoring and troubleshooting.

Impact

The improvements EDC made on Line 2 were substantial. Heytex went from a non-operational line whose parts were being cannibalized to keep an adjacent line running to a fully functional, efficient line with a state-of-the-art control system. Improvements included:

  • Streamlined workflow making it easier to go from the customer’s drawing to product runs, eliminating a full set-up step
  • Open source programs that can be modified and improved by any qualified service provider, eliminating proprietary software
  • An energy-efficient control architecture that is rugged, orderly and fully documented without reliance on ever-changing personal computer hardware
  • Improved control of the Oven conveyor, Tensioner and Rewind motors including better accuracy and synchronization through all speed ranges 
  • Improved Accumulator control that prevents finished product from touching the floor as was the case during Rewind roll changeover
  • User-friendly operator interface screens with more relevant operational feedback, alarms, messages and maintenance screens 
  • New capability to switch between patterns in the middle of a single roll and stop and resume a pattern if there is an Estop or alarm, potentially saving hundreds of yards of material per year
  • Remote monitoring and troubleshooting capability which was utilized to its full potential one month after start-up when Heytex needed to recalibrate Line 2 for new material. EDC was able to support them remotely and avoid a costly service trip from New Jersey to Virginia.
  • A retrofit platform with documentation, programs and drawings that can be utilized to upgrade Line 1, ensuring production viability for years to come

To sum up the benefits of the project, EDC’s VP of Engineering Chuck Dillard said, “If you look back, only Line 1 was operable. Now both lines are running, and Line 2 runs more efficiently with higher throughput than the machine’s original design.”

Overcoming Supply Chain Issues in Automation Through Flexibility

Posted on by Patty Davis

Since the start of the Covid-19 Pandemic, supply chain issues have been on everyone’s mind. It’s a universal problem that is not industry exclusive and has progressively gotten worse in 2022 as demand has soared.

The automation industry today seems to be at its wit’s end. Everyone needs parts, but parts aren’t available. Deadlines are getting pushed back. Lines are down. It’s getting harder and harder to put out these fires. 

Below are methods that Electronic Drives and Controls has employed to better tackle these supply chain issues and bring their clients relief.

Stay Early, Stay Ahead 

Evolution during a crisis is imperative to a business’ survival, so it will come as no surprise that many integrators have made certain changes to keep up with the ever-changing tides. EDC has always been creative in their problem solving, so it was an easy pivot for them to make a slight change in their project planning by sourcing parts as their first step, or as early in the process as possible.  

“On the front end of an upcoming project’s discussion, we tend to now look at availability of parts even before we start our engineering process. We used to engineer it, then find out that certain parts were not available, and then we would have to re-engineer it if we wanted to meet a particular delivery,” said Chuck Dillard, vice president of EDC. “Now, it’s a lot of coordination between our purchasing and engineering departments to pick the right parts and design around what’s available.”

Through front end work on a project, engineers can predict pitfalls and pivot where needed. Having an early plan and changing where needed is better than coming in later and improvising when challenges arise. This flexibility can be crucial during supply chain constraints.

Utilizing Third-Party Manufacturers

EDC has also turned to third-party manufacturers to help address challenges. Third-party manufacturers can be difficult to choose from and it takes extensive research, time, and experience to understand how to credibly source parts. When you’re on your own, there are quality and safety concerns to consider when ordering off of the web – that’s why EDC has invested the necessary time and effort to research and connect with the right sources. 

“For instance, if we want to get an Allen Bradley PLC, we go to Turtle & Hughes and we place an order with them. They order from the factory and then the factory says, ‘Oh, that’ll be four or five months,’ but we really need that PLC right away,” said Bob Pusateri, director of business development at EDC. “So, we purchase components from alternate sources.”

EDC keeps a well-researched list of possible sources in their back pocket to acquire parts as quickly as possible. They rely on their proven expertise to discern whether a part will be usable, even from somewhat-controversial online auction sites like eBay. They don’t make any sourcing decisions lightly, and they always employ a proper investigation before committing to a purchase. With the risk of faulty seals, or other safety measures at stake, working with an industry expert like EDC is crucial to ensuring the successful delivery of these hard-to-find items.

A Vendor-Neutral Strategy

As a system integrator and field service team specializing in over 40 drive brands, Electronic Drives and Controls maintains a vendor-neutral strategy, meaning they do not prescribe to only one OEM for all their projects. This has allowed the company to be more flexible and pull from an array of manufacturers. In turn, EDC is able to compare pricing and capabilities between vendors, allowing them to pass along the added value to their customers. 

Having strong alliances with world-class hardware and software providers around the nation, EDC has done the background work to ensure that their customers are getting the quality that they have come to expect. Through good relationships and a strong network, EDC has lowered lead times and sourced parts that would have otherwise been inaccessible.

The Benefits of Mixing and Matching

With an ample and extensive network of contacts, EDC has the added benefit of being able to pull parts from multiple resources when they’re ready, and as soon as possible. By utilizing a vendor-neutral approach, EDC is able to ‘mix and match’ parts for systems. By sourcing appropriate parts from alternative resources, EDC is able to better maintain project timeline expectations, allowing projects to be completed faster and with much less downtime.

In addition, through mixing and matching, the more cost-effective alternative can be purchased. Using one OEM for the HMI and another for the PLC offers the option to now choose the less expensive parts. This can also help cut down on the time needed to make a purchase, which means more time is going into actual engineering for the project.

What Does the Future Hold for the Supply Chain? 

Last summer, if you had asked a supplier when they expected the supply chain to start improving, they would have most likely estimated the summer of 2022. Yet, as most of us well know, that time has come and gone, yet supply challenges remain. 

Today, there is a mixed review, with some saying it’s getting better, and some of the opinion that it’s getting worse. This unpredictability can understandably be worrisome, but it is not cause for panic. 

When you’re stuck with downtime that is troublesome or you can’t get parts for the system that you rely on, EDC is proud to be your warranty. The supply chain is scraping the bottom of the barrel and the outlook is uncertain. Call on EDC, an experienced and knowledgeable integrator, to navigate this volatile landscape and make conscious decisions on your behalf. EDC has the resources to get your systems up and running.

Dave Radford, Longtime EDC Employee Retires

Posted on by Patty Davis

When Dave Radford started his career as a Drive Service Engineer in 1993, many of EDC’s current employees were not yet even born. Variable frequency drive (VFD) technology was just starting to take a foothold in the manufacturing sector and many PLCs that were released then have long been obsolete. EDC was a smaller entity with just six servicemen and even fewer project engineers (now almost twenty in total). Drives were just starting to be utilized in energy-saving HVAC applications and soon thereafter VFDs expanded their use of software and multi-layer circuit boards. So goes Dave’s career that spanned three decades and came to a close just last week.

Growing up in Elizabeth, NJ, Dave was an accomplished hockey player and chose to attend Lehigh University so he could play his chosen sport and study chemical engineering. He worked at his uncle’s bar and as a laborer at a now defunct roller bearing plant in Clark, NJ. Looking for some direction in life he joined the Army at twenty seven and was eventually sent to Fort Gordon in Augusta, GA to a unit that repaired communications avionics for helicopters. While Dave enjoyed the hands-on electronics work, he was “not thrilled” taking a couple of flights in the Army’s infamous “Huey” Bell UH-1 helicopters.

After several promotions, receiving the “Soldier of the Quarter” award and a 3-year tour of Panama and a stop in Fort Drum, NC he performed repairs on biomedical equipment for Army hospitals in facilities in Brooklyn, NY and Aurora, CO, returning home in May of 1993. Not resting long, he answered an ad placed by a long-tenured EDC recruiter who recently placed a Project Engineer just this year!

With a few strong years of repairing electronics for the Army, Dave was a perfect fit to troubleshoot, repair and install industrial drives for EDC. He tackled everything from plastic bag manufacturers to steel slitters to cardboard plants, older eddy current and DC drives, VFDs and later, EDC’s burgeoning new field of HVAC fan and pump drives.

Of the many stories Dave could tell of his troubleshooting travels, one in particular stands out from a steel plant in Gary, IN. After struggling all week to get their line restarted, they practically had a parade for Dave when he arrived on a Friday to dig them out of their hole as the Siemens Factory Service Rep. Despite the added pressure of just seeing it for the first time, Dave had the line running in less than a few hours. A parade would have been well-deserved!

EDC Dave Radford Retirement blog

Dave’s skill, intellect and professionalism will leave an enduring legacy. Many customers and EDC coworkers have benefited from his presence on an everyday basis. A very modest person, Dave would not be one to brag about, or even mention, his many success stories. It is estimated that he made well over 4,000 service calls during his 30-year tenure, repairing, troubleshooting or installing about 3,000 drives.  He was, however, glad to be a part of broadening the scope of jobs EDC tackles, especially helping them to expand into PLC programming and troubleshooting. As much as he enjoyed this very fulfilling work, he looks forward to moving to South Carolina and getting in as much golf, boating and, of course, hockey as he can. However, says EDC president, Bud Dillard, “we are pleased to hear that Dave has accepted our offer to work remotely as a Quality Control and Training specialist on a part-time basis.”

 

Case Study – EDC’s Comprehensive Upgrade of a Unique Horizontal Drawbench to Enhance Performance and Reliability

Posted on by Patty Davis

Electronic Drives and Controls recently successfully upgraded a unique horizontal wire drawbench, resolving complex challenges through hardware and software optimization, diagnostic enhancements, and safety improvements, resulting in enhanced performance, reliability, and operational efficiency.

Horizontal Drawbench

Problem:

A long-time client of Electronic Drives and Controls and an American manufacturer of scientific instruments faced numerous issues with their one-of-a-kind machine designed to draw and elongate copper bars filled with superconductors for use in magnetic resonance imaging (MRI) machines. 

Obsolete PLC I-O

After being custom-built by an original equipment manufacturer (OEM) in 2013, the machine experienced sporadic problems due to its

 complex design and programming. The existing PLC program, written in structured text using Siemens SIMATIC S7-300 hardware, was challenging to read and understand. Additionally, the PLC I/O modules were outdated, and the critical position sensors utilized an ultra-sensitive communications protocol that was subject to frequent “crashes,” made worse by machine vibrations. The client needed a comprehensive solution to address these issues and enhance the machine’s performance and reliability.

 

 

Solution:

EDC took on the challenge of upgrading the horizontal drawbench, providing a complete controls overhaul solution to optimize its performance. The project involved several key milestones. First, the existing PLC and HMI software programs were migrated from Siemens SIMATIC Step 7 to Siemens’ more robust Totally Integrated Automation (TIA) Portal. This transition improved program readability, removed obsolete code, and enhanced visualization and maintenance.

Hydraulic Lifter & Position Sensor

The hardware upgrade involved migrating the PLC from SIMATIC S7-300 to S7-1500, providing the client with updated components that offered improved performance, and reliability. Another significant aspect of the project was the transition from PROFIBUS to PROFINET, an Ethernet-based communication system. This switch eliminated existing issues, provided better diagnostic capabilities, and increased bandwidth. Approximately 40 devices were upgraded during this transition.

EDC also recognized that all existing I/O modules, specifically the S7-300 hardware, were obsolete. Consequently, each I/O module was updated to the latest Siemens S7-1500 series hardware, ensuring improved functionality and availability. The combination of the hardware and software improvements enabled optimization of the machine’s hydraulic lifters, key mechanical elements whose motion must be choreographed like a ballet to prevent a physical crash. EDC implemented a PID (Proportional Integral Derivative) loop control method around each lifter, resulting in precise coordination between them not previously realized.

To enhance network reliability, EDC introduced Device Level Rings (DLRs) into the machine’s network architecture. DLRs provided network redundancy, preventing downtime caused by a single faulty cable or device, facilitating efficient troubleshooting and issue diagnosis. Additionally, EDC revamped all drawings associated with the machine, including improved device references, wire numbering and enclosure layouts, providing comprehensive documentation for future reference and maintenance. 

 

 

 

Impact:

The completion of the project had a significant impact on the drawbench and the client’s operations, delivering several key benefits. 

S7-1500 PLC & ProfiNet Comms

First and foremost, the performance and reliability of the machine were significantly enhanced.

The hardware and software upgrades, coupled with the removal of obsolete code, resulted in improved stability and efficiency. In turn, there was no longer sporadic downtime experienced, ensuring a more reliable production process.

The transition from PROFIBUS to PROFINET granted the client enhanced diagnostic capabilities.

This allowed for better monitoring, troubleshooting, and prompt identification of any potential issues, facilitating faster resolution and minimizing downtime. The new HMIs improved visualization and readability making it easier for maintenance personnel to understand the machine’s operations, improving overall efficiency. Furthermore, the optimization of the control scheme and coordination with upgraded safety devices added protection and reduced the risk of failures or accidents, ensuring a safer working environment for operators.

 

In conclusion, EDC’s comprehensive upgrade project effectively tackled the challenges faced with this custom-built horizontal drawbench. The implementation of hardware and software improvements, coupled with enhanced diagnostic capabilities, led to a significant boost in reliability, efficiency, and maintainability. The successful completion of the project highlighted EDC’s expertise in resolving complex industrial automation issues and empowered a dependable machine to be capable of consistently producing high-quality, drawn super-conducting bars for MRI applications.

Case Study – EDC’s Modernization of a Ruesch Steel Slitting Machine Control System with Siemens Yields 67% Throughput Gain

Posted on by Patty Davis

In a recent project for a leading producer of specialty rolled products, Electronic Drives and Controls (EDC) successfully addressed a series of challenges stemming from an outdated Ruesch slitting machine control system. Characterized by obsolete hardware components, a complex operator interface, and difficulties in maintaining precise tension during steel slitting, the control system required an extensive modernization. EDC proposed a detailed control system upgrade, committing to an installation period of less than four days, leveraging modern Siemens technology to enhance hardware reliability, retrofit existing components, improve operator interface with a user-friendly HMI, and implement innovative torque management control for consistent winding tension.

The Client:

ATI Materials, a producer of specialty rolled products specializing in high-tech steel for aerospace and defense applications, operates as a critical supplier focused on precision aerospace engine and airframe components. They produce advanced steel alloys, including titanium, nickel, and cobalt-based materials in various forms such as long products, precision forgings, and machined components.

Problem:

The client faced significant issues with their aging Ruesch slitting line originally installed in 1995. The equipment’s legacy control system presented three primary challenges. 

1. The system’s reliance on obsolete hardware components, including SIMOREG 6RA24 DC Drives and Siemens TI545 PLC made it progressively difficult to secure replacement parts, thereby jeopardizing the system’s operational continuity and increasing the risk of downtime.
2. The operator control panel, with its complex array of analog functions, push buttons, and meters, hindered efficiency, making the system less intuitive and harder to use.
 3. The critical requirement of ensuring consistent tension across the material web during steel slitting was a significant challenge, given the current system’s difficulty in providing accurate torque control for the winding process.

Prior to Installation – Original Simatic TI545 PLC

Solution:

To address these challenges and provide a comprehensive solution, EDC proposed a control system upgrade using modern components and innovative technology:

Hardware and Software Upgrade: EDC replaced the outdated components with the state-of-the-art Siemens  6RA80 DC drives, S7-1500 PLC, and Siemens Comfort Panel HMI, ensuring reliability, scalability, and long-term support. Existing motors were retained, optimizing cost-effectiveness.

Installation and Retrofit: EDC’s engineers designed, built and tested the hardware and software prior to installation to minimize downtime for the retrofit. Sending a team of three engineers to work extended hours on site to install the new Siemens control system hardware and software further minimized production downtime.

Enhanced Operator Interface: An ergonomic 22-inch Siemens Touchscreen Comfort Panel HMI was installed to provide an intuitive and user-friendly operator interface. EDC programmed the HMI with meticulous detail to display over three dozen machine status messages and alarms making it easier to train operators and maintenance personnel to visualize and navigate the system effectively to keep production running at peak performance.

Torque Management: The EDC team harnessed the extended speed range of the existing DC motor to maintain predictable winding tension, even in the field range where torque no longer reacted linearly as field current decreased. This ensured the precise tension exiting the slitter section optimizing the quality of the slit edge. 

Advanced Communication: PROFINET was implemented to enable high-speed communication, replacing the previous PROFIBUS system. This upgrade enhanced speed, data processing, and control capabilities.

Remote Troubleshooting: EDC introduced remote access capabilities utilizing Tosibox secure remote access platform to streamline maintenance. If support is needed, the remote access into the machine’s control system facilitates a much quicker issue resolution.

Documentation: Using Siemens totally integrated automation software platform, TIA Portal, EDC provided a complete PLC, HMI and Drive functionality documentation package, including a fully commented PLC and HMI program, and drive parameters. In addition, using AutoCAD Electrical, EDC provided a robust complete set of schematics of not just the hardware components provided by EDC, but for the entire system including every limit switch, product sensor, push button, etc. to replace the clients’ outdated schematics.

Results

The modernization of the Ruesch slitting line’s control system yielded significant improvements in the customer’s operations. The machine’s throughput experienced a remarkable surge, increasing from 300 to 500 feet per minute. This remarkable 67% boost in productivity not only delighted the client, but also enhanced their overall operational efficiency. Safety measures received substantial upgrades, particularly with the introduction of an automatic slowdown feature to prevent material “tail-out.” This enhancement significantly reduced the risk of accidents and potential equipment damage, a critical advantage, especially when dealing with sensitive materials such as titanium.

Elevating Safety and Efficiency: Success in Machine Control Modernization

Posted on by Patty Davis
Foam Line

EDC recently modernized a foam production line for a client that specializes in the development and production of advanced wound care materials, enhancing safety features without extensive control system changes. Key safety components, including a door access interlock, a cable operated switch and emergency stop buttons, were integrated with a new safety controller. The project also included a provision for comprehensive schematics, previously incomplete and written in Chinese. EDC’s efforts ensured compliance, improved efficiency, and boosted the client’s global competitiveness.

Whether your machinery is aging or from abroad, placing a priority on safety can protect your workforce and offer a clear path for future enhancements. A recent project involving a client’s imported wound care foam production line, shipped from Asia to the U.S., highlights how a machine’s safe operation can be improved without major control system overhauls. EDC’s swift initiative, with only one week of on-site implementation, added crucial safety measures while ensuring continual efficiency to the production line. Not only did the project enhance safety, but it also provided comprehensive schematics, facilitating future improvements. 

 

Solving Safety Challenges

Upon the equipment’s arrival from overseas, it became evident to the client that the safety standards of the machinery for the foam production line did not meet U.S. machinery safety requirements. A key element to the upgrade was the addition of a safety controller, ensuring that all safety components were properly coordinated and monitored across various sections of the line. The controller makes certain that a malfunction of any of the safety devices prevents the foam line from operating until the issue is resolved or the fault cleared. The controller analyzes real-time status of the safety devices and initiates emergency shutdowns when necessary.

In conjunction with implementation of the safety controller, additional failsafe components were installed where none were present. Previously a padlock was used on a door to an access point near a critical area of the machine’s production process. When the padlock was removed to access the area, the machine could potentially be run with the doors wide open.

New HMI with Safety Monitor Screen

To solve this, EDC introduced a safety interlock system from Fortress Safety that features a solenoid interlock. This device prevents a door from opening without first engaging a stop button or a supervisor’s override button, requiring deliberate action be taken to access the area. The safety controller ensured that once the door was opened, the machine could not be operated. 

Next, a cable-operated switch, which functions as an emergency stop, was installed at the Rewind end of the line. Operators could also take advantage of the device’s E-stop button, located at knee-level, for additional safety control. 

Finally, all existing E-stop buttons were replaced with late model equivalents with up-to-date safety ratings. A dual channel E-stop string tied to the safety controller ensured the utmost in failsafe reliability.  Status of all safety components was displayed on a newly installed HMI ensuring operators are informed and have multiple ways to take immediate action in case of an emergency. 

 

Empowering Safety and Efficiency

The project relied on advanced technological components provided by distributor Shingle & Gibb, including: 

Banner XS26-2 Safety Controller: The heart of the safety integration, this controller monitors all connected components and ensures safe operation of the line.

Siemens PLC (S7-1200): A programmable logic controller (PLC) that works in tandem with the safety controller, communicating status information to be displayed on the HMI. 

Siemens SIMATIC Comfort Panel HMI: The HMI serves as the interactive hub where operators can monitor and control the machine. It displays real-time warnings and alarms, further bolstering safety.

Siemens Safety E-stop Buttons: Mushroom head, twist E-stops with the latest EN ISO 13850 safety certification.

Banner RP-LS42F Series Cable Operated Switch: Commonly referred to as a “rope pull,” this device provides an E-stop function over a wide area of the machine that can be actuated by a hand, knee or foot.

Fortress Safety Interlock: This switch is critical in safeguarding operators and machinery by preventing unauthorized access during operation.

Timeline and Deliverables

The entire project took a few weeks over the course of approximately three months to complete, with one crucial week of on-site installation work. During this on-site phase, the team installed and wired all the safety components, tested the programs and conducted extensive testing to ensure proper functionality.

Also included as a project deliverable was a full set of schematic drawings for all new components and the line’s existing devices that did not change. EDC’s provision of machine schematics built upon the client’s current documentation and improved the understanding for the control system, providing a valuable tool for not only troubleshooting and routine maintenance but also for making future modifications to the control system. Offering the client the option to receive detailed drawings and schematics allowed them to gain a clear image of the equipment’s connectivity, enhancing safety, reducing downtime, and creating opportunities for additional projects. 

 

Beyond Compliance

By modernizing an imported machine with a series of well-thought-out safety controls, EDC ensured that the client’s equipment met local and national compliance requirements without a major control system overhaul. Operational efficiency was improved by employing a Banner Safety Controller, Siemens PLC and an intuitive HMI that provided operators with real-time information about the machine’s status. By investing in modernization and implementing safety controls, the client was able to mitigate risks, protect their workforce, and meet the highest safety standards – all while maintaining their production efficiency and competitiveness in the global market.

Modernizing Industrial Machinery: A Strategic Approach to Retrofitting with EDC

Posted on by Julia Plott

EDC’s client bought a slitting machine that was in pieces from an auction.  EDC engineers were excited to give new life to a line that was in a used equipment warehouse.

Case study by EDC Project Manager Joe Maloney

Problem

Reviving outdated machinery with modern controls demands strategic planning. This was the case when an EDC client acquired a 1960s-era Ruesch Slitting line from an auction. “The client bought the individual pieces of the slitting line. Everything was obsolete, defunct,” said EDC Project Manager Joe Maloney. “The client didn’t have any electrical drawings. Everything had to be refurbished and there were no controls. The client bought this slitter and they needed us, the systems integrator, to provide controls and integrate it back to working condition, which was no small feat.”

For cost and timing reasons, the client had chosen refurbishment of older equipment rather than investing in new equipment.

Once running, the line would be tasked with slitting 200 meter runs of a thicker gauge steel laminate material used in making bearings.  With no welding system in place to link subsequent coils together, the material tails out at the end of each coil.  

Challenges

In addition to possessing obsolete controls, among the primary challenges was the presence of outdated Parker SSD DC drives. 

Reusing the existing drives required extensive refurbishment and rewiring to integrate them with a modern control system. This choice was driven by both cost considerations and the compatibility of the drives with the line’s existing components. The client’s choice to use the refurbished drives presented additional challenges with outdated connectivity interfaces, such as the need to program drives through serial cables due to the absence of Ethernet connectivity.  “Without the refurbished drives, we could have used a high-speed Ethernet protocol to communicate things like run commands and line speed. Because of the drives, everything had to be hardwired,” said Joe Maloney.

“We followed strict arc flash rules to gain access to the panel, wearing the full personal protective equipment (PPE) suit,” said Joe Maloney. “All these old drives don’t connect over Ethernet, so you have to program them through a serial connection. The hard wire, the run, the speed reference, all the feedback – all that eats up your available IO.”

 

Solution

With an ambitious project timeline of four months and needing to meet additional safety requirements, the client aimed to integrate controls into the acquired line. With a focus on compliance with safety standards and certifications, EDC offered flexibility in programming and integrating the outdated controls and fragmented machinery.

 

The line’s layout comprised six primary components, each playing an important role in its operation. These included:
1. Uncoiler section: Where the material is unwound and fed into the machine
 2. Slitting section: Where the actual cutting process occurs
3. Scrap winder area: Manages the disposal of scrap edge trimmed material
4. Tension stand: Isolates tension between Slitter and Recoiler
5. Recoiler: Rewinds the processed material
6. Turnstile: facilitates material handling and movement within the line

 

 

 

 

While reusing the legacy Parker SSD DC drives, EDC engineers retrofitted the slitting machine with a modern PLC and HMI; the controls software was programmed from scratch.  To enhance functionality, EDC modified the operator stations by streamlining interfaces and optimizing control panels. Rockwell Automation / Allen Bradley components were used for the retrofit, including the installation of a CompactLogix PLC and a PanelView HMI, enhancing control capabilities and providing a user-friendly interface for operators. 

In addressing the outdated DC motor used in the scrap winder area, EDC opted for integration of a new AC motor. This replacement not only eliminated the limitations associated with the obsolete DC motor but also improved efficiency and reliability in material handling operations.

Since the line’s speed could exceed 100-200 feet per minute as the coil finishes, the metal tail could pose a safety hazard.  “I programmed in a footage counter and an auto stop on the slitter so the customer could stop near the recoil,” said Joe Maloney. “Once you reach the preset length, it shifts your set point down to a slow speed, and then you run at that slow speed for a short amount of time before it is turned off. We provide the flexibility of being able to have custom programming to meet the client’s specific situation and needs.  We can even add features at a future time as the production evolves.”

Another customization was adding a sensor that integrated with the hydraulic system to automatically provide tension stand positioning.

Results

“It’s almost like we took a bucket of parts and helped them put it all in place and then completely reprogrammed everything from scratch,” said EDC Vice President of Systems Chuck Dillard. “You can get a line from a used equipment dealer, not know much about it and have junk for electrical parts. Our engineers were able to put it together utilizing many of the original parts to create a fully-functional machine.”

“It can take months, if not years, to build a new piece of equipment rather than getting a used piece of machinery,” said Joe Maloney. “By taking older equipment and updating the controls, you can save not only time, but also a lot of money – and that gives you an extra 20 or 30 years of life on that equipment.”

Through retrofitting, integration of modern components, and adherence to strict safety regulations, the slitting line was transformed into a reliable and efficient asset for the client. Despite the many challenges posed by outdated controls, lack of documentation, complex wiring, and more, EDC successfully restored the equipment’s functionality. This slitting line will contribute to the client’s operations for years to come, offering a cost-effective and sustainable alternative to investing in new equipment.
