BOMA NY Members Wowed by One World Trade Center

Electronic Drives and Controls BOMA OWTCLast month, the Building Owners Management Association (BOMA) of New York hosted their first off-site Brunch N’ Learn at One World Trade Center, highlighting the latest technology in vertical transportation from ThyssenKrupp Elevator. Electronic Drives and Controls, Inc. (EDC) has been a BOMA, NY member for 11 years.  EDC’s Deborah Deluca, Vice President, serves as a volunteer on the professional development committee of BOMA NY. She coined the idea for Brunch N’ Learns, otherwise known as Lunch N’ Learns, back in the summer of 2016 in an effort to increase interest in the organization’s membership program. Since then, Deb has been deeply involved in the planning and production of these monthly events for BOMA members.

Deb reflects on the success of this month’s Brunch N’ Learn, mentioning that “One World Trade Center (OWTC) was a special location for BOMA members to visit as it has both the fastest elevators and is the tallest building in the Western Hemisphere.” At 104 floors tall and 2.6 million square feet, the building has 71 elevators that reach speeds of up to 23 MPH- 2,000 feet per minute. “Twenty BOMA NY members including property managers and commercial real estate representatives joined us to learn more about this very impressive building and what’s new in vertical transportation.”

EDC BOMA NY ThyssenKruppJoe Cossentino, Director of Vertical Transportation for Syska Henessy Group Inc., opened the event, giving BOMA members a glimpse into the history of the World Trade Center site since its humble beginnings, hosting a 22-story railroad terminal in the 1900s. Today, OWTC stands tall on the site as a symbol of hope and perseverance for New York after the tragedies of 9/11.

Joe mentions that this presentation was particularly special for him as he was a project manager of mechanical engineering, overseeing the design of 30 elevators and 50 escalators, during the rebuilding of OWTC from 2004-2013. He says, “It was a privilege to be part of the design engineering and rebuilding of the World Trade Center Site in New York City. From the day that I witnessed the tragedy on 9/11 from midtown Manhattan, to the day that I stood on the 104th Floor of One World Trade Center as they poured the final concrete slab, our sense of respect and reverence for the families and first responders, along with our sense of accomplishment and renewal by the entire design team, was part of our shared experience.”

EDC OWTC BOMA NY ThyssenKruppJeffery Smith, Director of New Installation Sales in New York for ThyssenKrupp Elevators, then took the stage to deliver an innovative presentation on the future of elevators and building technology. Kenny Peng, an Account Manager for ThyssenKrupp discusses the presentation mentioning, “Attendees were given an inside look at how our new elevator systems are going to revolutionize tall building construction not just in New York, but around the world. One example of this is our groundbreaking rope-free elevator system called MULTI. MULTI elevators allow passengers to travel horizontally and diagonally in addition to classic vertical transportation. The elevators operate in a manner that compares to that of a subway, where multiple elevators run independently but within the same hoistway. This was of high interest to attendees as it is a completely new concept for elevator technology and the first building to incorporate this kind of elevator system is currently being built in Germany.”

EDC BOMA NY Brunch N Learn ThyssenKruppAfter boggling minds with elevators that go multiple directions and at lightning speeds, attendees toured one of the elevator machine rooms, where 6 of the building’s 71 elevators are located. Deb notes, “This part of the event was a great opportunity for attendees to have firsthand interaction with ThyssenKrupp Elevator technology.” The floor was then opened for networking and questions for the speakers.

The BOMA NY/ThyssenKrupp Brunch N’ Learn was a great success. “BOMA members left the Brunch N’ Learn with a deeper breadth of knowledge on up-and-coming technological advances in vertical transportation with a behind-the-scenes look at one of the most impressive buildings in the world,” said Deb.

Top 4 Reasons to Implement a Control System Preventive Maintenance Program

What is Preventive Maintenance?

Preventive Maintenance (PM) is a program designed to maintain optimal function of your control systems (Variable Frequency Drives (VFDs), PLCs, etc.) in real time while also preventing deterioration and failure in the future. With regularly scheduled maintenance, PM allows users to realize the greatest return on their investment.

How does Preventive Maintenance work?

Preventive Maintenance procedures are carried out on a prescribed basis, customized to the specific needs of each control system. During PM, controls undergo various physical, visual, and electrical inspections in addition to regular maintenance procedures including predefined part replacement and fine-tuning. Any irregularities are identified and remedied before they have the opportunity to magnify and cause more serious and potentially costly damage. Each procedure concludes with full documentation of the controls system’s condition at the time, creating a history file that helps predict future maintenance needs.

Why implement a PM Program?

While there are many important reasons to implement a Preventive Maintenance (PM) program for the control systems in your facility, there are four that stand out from the rest:

EDC Electronic Drives and Controls Preventive Maintenance Heat Sink Clog
Clogged heat sinks can lead to degradation of VFD performance.

 

     1. Prolongs Life of Investment

Did you know that a drive without Preventive Maintenance could have a life expectancy as low as 3-4 years before problems climb beyond economical repair? The same drive could have a life expectancy of 12-15 years or more if well maintained. Without PM, it’s difficult to tell if your drive is operating under ideal conditions or not. Non-ideal conditions put stress on crucial components such as IGBTs, capacitors and other sensitive electronics that can significantly reduce their life-expectancy. With PM, operations users realize low peak-demand rates, drive reliability and an improvement in the return on investment of their drive.

 

     2. Minimize Downtime

Electronic Drives and Controls Infra-Red Connection Problem Preventive Maintenance
Faulty connections made visible with infra-red technology can cause future problems if not promptly fixed.

Control system failure can cause major downtime in operations, costing businesses thousands of dollars. Preventive Maintenance is meant to reduce the chances of control system failure and the severity of failures if they do happen. Industries at the highest risk for losing a great volume of assets due to downtime include pharmaceutical, medical, wire and cable, and more. For example, a pharmaceutical company that relies on their drives to keep their facility and laboratories sterile could lose hundreds of batches of product and have an experiment that has lasted years be completely compromised by an unsterile facility if their drives were to fail.

 

     3. Maximize Energy Savings

To paraphrase and old pirate yarn, “Dead drives save no energy.” Preventive Maintenance programs ensure that control system’s energy consumption matches energy requirements. Mechanical systems controlled by drives and/or PLCs that unnecessarily operate at high energy consumption, endure stress that can reduce their life expectancy. With PM, systems run efficiently, reducing energy related costs and the facility’s overall carbon footprint.

 

Control Systems Messy Wiring Preventive Maintenance
Messy wiring can cause difficulties during trouble shooting and even lead to control failure if not remedied.

     4. Maintain a Knowledge Base of Equipment

After each Preventive Maintenance procedure, the information collected including inspection, updates, comments, suggestions and more is logged into a system that contains the operating history of each drive or PLC with PM. At first, this may sound like a small piece of a large puzzle when it comes to the upkeep of control systems. However, having a knowledge base of a control system’s history can be highly predictive for future maintenance needs and problems. In the long run, this helps decrease damage related costs and increase operational reliability.

Traverse Spool Winder Mechanical and Control System Upgrade Results in 40% Productivity Gain

Traverse Winder Electronic Drives and ControlsA customer who is a premier manufacturer in the metals industry came to us hoping to increase productivity and decrease downtime.  The company markets strips made of innovative copper alloys, serving the electronics industry and other demanding markets that require the highest quality copper-based alloy strip available. This customer was experiencing downtime with its multi-strip traverse spool winding line related to its 20-year-old, obsolete General Electric control system. In addition to downtime, the line had never run at its max speed due to the loss of tension during the wind and unwind process. The inconsistent tension through the slitting section compromised the integrity of the splice causing quality control concerns.

In the steel industry, if your metal converting process is compromised, losing a roll of steel due to poor quality is an expensive consequence. With the mounting downtime and quality concerns, the company decided a major overhaul to the traverse winding line was needed. The company’s plant maintenance manager was tasked with successful completion of this project on a very aggressive timeline. Production needed to be back up and running before depleting the company’s built-up inventory. This required the entire custom mechanical and controls system retrofit be completed in just 3 weeks, which required seamless planning and execution.

Having hired Electronic Drives and Controls, Inc. (EDC) for smaller controls-related projects, the customer trusted EDC’s expertise to meet the company’s goals for the project. “EDC exceeded our expectations by having the line back up and running in just two weeks. We are all over the place with technology – Siemens, Rockwell and General Electric. EDC’s team has been great to work with because they really understand and can troubleshoot a wide variety of systems,” said the plant maintenance manager. “They are very professional onsite and always provide great documentation post-project. In addition to that, EDC’s team has always worked with us to complete projects within very tight time frames.”

“Results have been excellent,” he continued. “With the increase in running speed, we have nearly doubled the output. We always had the capability of running at a higher speed, but we could never achieve that speed because we could not control the tension enough – that was always the problem. We have realized a 40% increase in productivity since project completion.”

In a recent interview, Chuck Dillard, vice president of EDC, shared some of the ins and outs of the project and gave us insight on the success.

How did this project come about?

Obsolete GE PLC and Drives

Chuck: “Several years ago, the customer was referred to us through one of our other customers that builds machinery. We soon started doing retrofits on what they had for traverse winding controls. Over the years, we have retrofitted six Ruesch Sidewinders into their production line. Last year, after they were experiencing persistent problems with tension control, they decided it was time to update the entire line.”

How exactly did EDC update the customer’s traverse winding line?

Chuck: “For traversing, we converted the hydraulic cylinder technology into electric linear actuators using servo motors with ball screw drive technology to achieve high thrust forces while maintaining the ability to produce repeatable, programmable motion. We also replaced all the variable speed drives in their cabinets and their PLC using Siemens S-120 vector, S-120 servo and S7-1500 for the PLC. For the operator interface, we used a Siemens Comfort Panel touchscreen human machine interface (HMI). We created a custom mechanical design, so they could very easily pull out the hydraulic cylinders and put in this electric actuator. The new electrically powered system was able to provide thousands of pounds of thrust with the linear actuator and then we interfaced it with the traverse winder controllers that we had upgraded a while back.”

Going from hydraulic cylinders to electric actuators, how does that impact the overall picture, and why did you want to do that?

Drive Lineup- 6RA80 DC, S120 Servo and S7-1500 PLC

Chuck: “Hydraulics are not nearly as efficient as an electric motorized system. Electric linear actuator systems use power as it is needed for traversing, in comparison to needing to have a big hydraulic power unit running at all times. Hydraulics are also very messy; their oil leakage causes the surrounding floors to be very slippery which is a big safety hazard. They are constant maintenance, from regular cleaning to more in-depth maintenance requirements. The electric servo gives the ability for more flexible, precise, and reliable control to follow the exact command for the traverse position requirements.”

How has operation of the equipment changed?

Chuck: “The customer has benefited greatly from an operational standpoint as a result of this upgrade. In the past, they had tension issues and had to slowly increase the speed. It made it hard for the management to give directions to run the line at a higher speed because the operators would run into issues and lose control of the line, leading to bad product that costs a lot in waste and scrap. During a run, they start with several master rolls. They run a master roll, then they have to splice a new one in. They can have 8 welds per traverse-wound reel.  It’s important to maintain really good tension during the time they are stopping to make the weld and starting after the weld for the traverse wind to keep its integrity. Now, the tension issues have been resolved and they can just hit a start button and the line ramps right up to 600 feet per minute maintaining tension on all of the dancers.”

What were the results of the retrofit?

Chuck: “The customer’s average running speed prior to this project was 350 feet per minute – and even then, they were nervous to run the system at full speed with the risk of failure.  Now they are regularly running at 600 fpm and are capable of running up to 850 fpm on a 1” strip which is a pretty impressive response on a traverse winding setup. With the increase in the overall speed of their line and the ability to now hold tension during acceleration and deceleration, they are realizing a 40% increase in productivity with much better quality.”

Uncoiler and Slitter DC Drives with Double Motor Modules for Servo Driven Actuator

What contributed to the success of the overall project?

Chuck: “Winding and unwinding applications are certainly in our wheelhouse. We specialize in tension control and have engineered, built and retrofitted controls for hundreds of pay-offs, take-ups, rewinds and unwinds. Proper planning, project management and execution from start to finish is critical. We handled the entire project. Therefore, we had control over coordinating all the moving parts to achieve success in the tight time frame required. After the design phase, we completed as much of the programming and build as we could at our facility. On site, we had everything lined up and ready to go. We provided electrical contracting to run cables, wires and conduits. We did the mechanical retrofit on hydraulic cylinders.  We replaced all of the panels within the enclosures.  We performed start-up and connected all the wiring.  In two weeks, the line was up and running with a significant improvement in productivity.”

Conclusion

The customer’s traverse winder line upgrade has proven to be a great investment. The plant manager shared his experience working with EDC over the years saying, “EDC does what they say they’re going to do. They were able to perform this project in a very tight time frame for us. Time is critical for us – EDC worked odd and extended hours to make this happen. We do not have redundancy in equipment, so the retrofit had to be quick. EDC originally estimated the project would take seven weeks, but they were able to revise their schedule to do it in less than the three weeks we gave them to complete the project.”

Film Coating Line Downtime Resolved with EDC’s Successful Drives & Controls Upgrade Using Rockwell Automation Products

Manufacturers across the country are faced with the challenges of costly downtime related toEDC coating lineaging equipment with obsolete drives and control systems. At some point, trying to patch and repair outdated systems becomes unrealistic. The good news is that investing in new advanced drive and control system technology can breathe new life into your equipment and provide a significant return on investment (ROI). The ROI can come in multiple forms including savings on downtime, improved system efficiencies, remote system capabilities, energy savings, increased safety, or a combination of those benefits. Our project at ORAFOL demonstrates how success can be achieved by investing in a major retrofit.

ORAFOL Americas Inc. is a global manufacturer of graphic films, reflective solutions, and adhesive tape products for a variety of industries. The company’s Avon, CT plant manufactures the leading brand of DOT-C2 compliant conspicuity tapes for the heavy-duty truck and trailer market.

ORAFOL was experiencing significant downtime on an existing film coating line due to aging equipment and legacy control systems. The company decided it was time for a major overhaul including replacing some equipment with new and retrofitting obsolete controls on the entire line. The coating process is very intricate, requiring expert engineering knowledge of complex winders, tension controls and web transport systems.

EDC provided a robust turnkey solution using Rockwell Automation technology and was responsible for all aspects of the project, both mechanical and electrical including design, procurement, removal, installation, along with the startup and tuning. In addition, EDC managed vendors, suppliers, other engineers, and machine shops; a lot had to come together at the same time to make a project of this magnitude flow smoothly.

ORAFOL now has a reliable, modern, state-of-the-art coating line with many benefits. To read a detailed case study on the project, click here or download the PDF.

When interviewed after its completion, ORAFOL’s Director of Engineering, Gary Gauer, expressed his delight with the project, “The EDC team delivered exactly what was promised and worked with our engineers to customize the system to the satisfaction and ease of the machine operators. EDC demonstrates a very strong commitment to their technical expertise, understanding the latest products that are available and having a technical acumen with those products. They are proficient as well as being responsive and personable.”

When the Problem Isn’t the Motor, It Doesn’t Mean It’s the Drive

Scott SullivanBlog post by Scott Sullivan, electrical engineer at Electronic Drives and Controls who specializes in on-site field service of AC drives.EDC motors drives

Recently, I was called in to troubleshoot a customer’s air handler drive. This particular unit was blowing fuses on its input from the main line. The customer’s in-house electrician correctly determined that something was drawing too much current. He then decided that the problem had to be with the drive or the motor. For testing purposes he bypassed the drive, which he believed left only the motor. When he attempted to start the motor, the fuses blew again. Since he believed the motor and drive were the only possible culprits and the drive was bypassed, he figured the motor had failed and so he installed a new motor. This time when he tried to start the new motor with the old drive, the fuses still blew. His determination was that both the motor and the drive had failed. At this point I was called in to troubleshoot.

After being given a brief summary of the problem, I started to examine the drive. After a thorough examination I didn’t find anything wrong with the drive that would explain the issue. To test my hypothesis, I disconnected the motor from the drive and tried to start. If the drive had been the problem, the fuses would have blown at this point. The fuses remained fine, so the problem was not between the main line and the drive. This left only the output wiring and the motor. Since the motor was brand new, it was unlikely to be the problem. Therefore, the output wiring was the only issue remaining. With the aid of the customer’s electrician, I ran new wire from the drive to the motor and tried to start. The motor and air handler started up without an issue. After examining the wiring I found that some of the insulation had worn off and part of the live wire was touching the metal conduit. This caused a short to ground and caused excessive current to be produced, thereby blowing the fuses. If the fuses had not blown, the drive would have most likely failed, possibly burnt up the new motor, and maybe even caused a fire.

The lesson to be learned here is that there are many causes for fuses failing. Just because you eliminate one cause doesn’t automatically mean it has to be something else. This customer spent money on a new motor when they probably didn’t need it. When you determine a problem has occurred and you don’t know how to fix it, the best solution is to ask for outside help. It may actually end up saving you money.

A NYC Building with No A/C in the Middle of a Summertime Heat Wave!

On June 13th 2018 EDC received a worried call from Jack Resnick + Sons’ Chief Engineer Scott Stefanski, with a problem on the company’s property, One Seaport Plaza in New York City. Scott had discovered that the drive powering the building’s lobby air conditioning had gotten wet and was destroyed. As the heat in the lobby steadily increased, Scott realized this problem was going to cause more than just discomfort to the building’s patrons. The lobby also featured artwork worth millions of dollars that, if exposed to high levels of heat, would be destroyed. Knowing new drives usually require more lead time than he could get away with in anticipation of another 90-degree hot and humid day, Scott was scrambling to find a quick solution.

EDC’s Sales Representative Eric Dillard was the one to receive Scott’s late-afternoon emergency call. Immediately, Eric reached out to EDC’s Service Manager Gregg Martin, to see what he could do to help. Lucky for Scott, he reached EDC before the local vendors closed for the day.  After Gregg had made a series of unsuccessful calls, he was finally able to find Scott the appropriate replacement for the lobby’s broken drive.

Bright and early the next day, EDC sent out Scott’s new drive with Service Engineer, Marius Bagdonas. Marius was able to reach One Seaport, NYC early that afternoon and had the drive installed within 24 hours of Scott’s initial call.

Scott expressed his appreciation saying, “EDC did not have the drive we needed on hand but went out of their way to source it for us. The following afternoon they had the new drive installed and our lobby air conditioning was back up and running. EDC is a new vendor for us; I was really impressed and happy with how quickly they were able to respond and help us out of a critical situation. It’s refreshing to work with a company you can count on, and really cares about their customers. I have already been recommending EDC to my counterpart Chief Engineers at our other buildings!”

Emergency service calls like Scott’s come to the desks of EDC’s service department every day. EDC is committed to reducing the impact these types of problems have on customers by solving them as quickly as possible without sacrificing the quality of work.

Spare Equipment Needs Maintenance Too

Failure to maintain spare equipment can cost you money and downtime, as well as being a safety issue.

Scott SullivanBlog post by Scott Sullivan, electrical engineer at Electronic Drives and Controls who specializes in on-site field service of AC drives.

Nobody likes downtime. In industry, you lose money every minute that product isn’t going through a machine. In HVAC applications, downtime usually leads to complaints from sweaty people in the summer or freezing people in the winter. In extreme cases, having one machine down can cause other machines to run improperly, resulting in damage and more downtime. For simple applications, a bypass circuit can be implemented to prevent downtime but this comes at the cost of only being able to run at 100% speed. This forgoes the energy savings usually associated with drives and is incompatible with processes that require variable speed. When downtime isn’t an option and a drive is required, the most common solution is to have a spare AC drive on site for a quick installation. However, failure to maintain this spare equipment can lead to downtime anyway- and added costs.

Similar to how you can’t put a battery that’s been sitting in your garage for years right into your car, AC drives can’t just be wired in if they’ve been sitting on a shelf for years. AC drives contain capacitors, which have a very small amount of insulating oxide separating the conductive material. This material degrades over time but is chemically replenished within the capacitor as long as voltage is applied. If no voltage is applied, for example if the drive is in storage, the material still degrades. If you were to try to apply full line voltage to a degraded capacitor, it will most likely fail in a horrendous fashion due to this material shorting out.

So what do you do if you have a drive that has been sitting around for a while? Using the previous example of a car battery, you would hook the battery up to a trickle charger and let it sit for a day. AC drives require a very similar procedure where you hook up a lower voltage circuit to provide a small current to the capacitors. This allows them to chemically rebuild the insulating oxide layer without the danger of shorting the capacitors. For safety, a series resistor or a fuse is commonly used in case too much current is generated. This process is known as “reaging” or “reforming” the capacitors. Consult your user’s manual for the drive for specifics on how this is done. Typical times are 1 hour of charging per year of inactivity and should be performed every 1-2 years of inactivity. My recommendation is to write on the drive, in big black letters, the last date the drive was in service. That way you know if a charging is required and how long to charge if it is needed. If you are unsure of how long it has been since a drive was in use, call a service center. Most drive service companies will either let you send them the drive for capacitor testing or reform the caps on site at your location.

I’m reminded of a service call I had not too long ago. A customer’s drive had failed and it was going to be a couple weeks until I could get spare parts to repair it. The customer had a spare drive from a similar unit that was decommissioned and he asked if I could just install that drive in the meantime. The drive was compatible, but I could see from the manufacturer’s label that the drive was close to a decade old. I asked the customer when it was last in service and he said, rather vaguely, “not too long ago.” I explained the risks and he asked me to install it anyway. I installed the drive and shortly after powering it on there was a loud bang. One of the drive’s internal capacitors had exploded and damaged most of the drive’s other internal components. The drive was beyond economical repair, so the customer had to wait a few days until I could get another drive to install. It was at this point I learned the customer’s definition of “not too long ago” was about 6 years, whereas the manufacturer’s maximum idle time for the drive was 2 years.

Had the customer in my example been aware of this or kept some record of the last time the drive was in use, I would never have installed it. Capacitors exploding is dangerous to both equipment and nearby personnel. Always keep your spare equipment maintained and have the maintenance performed by qualified personnel. This customer ended up having to buy a new drive to replace the spare, money that he would not have had to spend if the drive was kept in working order or the capacitors were reformed.

 

EDC Welcomes Tom Frangieh and Anthony Fasolo

Our team is growing!  We would like to introduce a couple of new faces you will be seeing on the Systems Team at Electronic Drives and Controls (EDC).

“We are very excited to have Tom Frangieh and Anthony Fasolo join the EDC team, both bring unique talents and skillsets which will help our team meet the ever expanding needs of our industrial automation customers,” said Chuck Dillard, vice president of engineering at EDC.

While working at the Rowan University Virtual Reality Center as an undergraduate, Anthony was invited to enroll in graduate school, funded by the Center.  In his experience there, he worked with many higher-level computer programming languages such as C and C Sharp, and did a lot with visualization – virtual and augmented reality.  Anthony’s favorite project while at the Virtual Reality Center was an application he developed for the Microsoft HoloLens, an augmented reality headset.  The HoloLens allows programmers to overlay information on whatever the wearer is viewing in the real world.

“I had a customer come to me and ask for a demo application to show his idea for training surgeons,” said Anthony.  “He wanted to display an instructional video in a floating screen on an augmented reality device.  The surgeon-in-training wears the device and watches the instructional video while performing a surgery, and controls it by voice commands.  Instead of having to leave the operating room and go watch the instructional surgery video on a TV and then come back to the operating room and try to remember it, the surgeon would be able to watch the training video while concurrently performing the surgery.  It was a very cool project, and the customer was really pleased in the end.”

After the Virtual Reality Design Center’s student funding ran out, Anthony left the college just a couple of classes shy of achieving his master’s degree.  Now at EDC, Anthony has been spending time becoming familiar with the software systems the company uses to program drives and control systems.  He says, “I have the knowledge for it, it’s just looking at something new and trying to figure out how it works.  I’ve always had hands-on experience with wiring and electronics because I worked as an alarm technician in the past.”

In his spare time, Anthony enjoys building hobby electronics.  He also enjoys watching professional football and hockey, and his all-time favorite team is the New Jersey Devils.

Anthony, like Tom, is a longtime friend of Eric Dillard – they all attended high school together!  Anthony looks forward to better getting to know the rest of the EDC staff.  “It’s been really good these first few days.  Everyone has been very helpful working with me and teaching me,” he said.  “They are good guys over here; I like it a lot.”

 

Popularity Soars for Annual EDC Wall Calendar, 38th Edition Coming Soon

1981: EDC’s first wall calendar
Dane Radford, son of an EDC employee, was recently at the bus transfer station in Secaucus, NJ, and on the wall in the back of the ticket office was a 2018 EDC wall calendar. “I asked the ticket agent where the calendar came from, because EDC doesn’t work with New Jersey Transit at this location,” said Dane. “The agent said he asked a friend for his calendar because he liked it so much. He said it’s so convenient to see the whole year at a glance. We don’t know which of EDC’s customers was the original calendar recipient, but we are happy to have the calendar in such a visible location!”

In 1980, EDC’s vice president Bud Dillard decided the company should allocate some of the marketing budget for promotional items such as caps, t-shirts, pens, etc. He came up with the idea to print wall calendars to send out to the company’s most important clients as holiday gifts. Bud originally wanted a 12-page Norman Rockwell version with heartwarming illustrations. Unfortunately, the price was too high to print the number of copies he wanted, so he settled on a less expensive wall calendar printed with the company’s name and contact information. Bud and the EDC team distributed all 150 copies in the first printing for the calendar year 1981.

Call the wall calendar design decision either dumb luck or good fortune, but the calendar program is still extremely popular at EDC. Fast forward 38 years and the popularity has been so great that EDC has capped printing at 5,200 copies for 2019. “We could probably distribute about 20,000 calendars if we wanted to – they are very popular with our clients,” said Bud. “We have kept the calendar printing cost proportional to our revenue, so the program has grown along with the company.”

EDC employees tell plenty of anecdotes about the popularity of the calendars. “One gentleman visits us in the office each year and asks for a calendar using sign language. We are happy to oblige him,” said Bud.

Sending out 5,200 calendars is a large undertaking each year for EDC. “Every year, as the calendar mailing project is in full swing, I swear this is the last year, never again, and it’s not worth it,” said Bud. “Then, within a couple months, someone says to me, ‘Hey, I saw your calendar! Jeez, your calendars are everywhere!’ Then I think… Hmmm, maybe one more year. I am presently in the never again mode.”

EDC Repairs “Unfixable” Elevator VFD, Saving Customer 90%

 

Novartis elevator VFD repair

For facility managers, an elevator being down is always an annoying issue to deal with. But when that elevator is one of just two in a major pharmaceutical headquarters’ 6-story parking garage serving multiple office buildings, the inconvenience for facility occupants’ commute exasperates the annoyance exponentially. This is exactly the situation Ken Prokop, facility manager at Novartis Headquarters, had on his hands when the critical parking garage elevator was down due to a 12-year-old VFD that was not performing properly.

Ken needed the elevator back in service quickly. He started his search for a solution with the seemingly obvious choice of the elevator vendor handling maintenance on the elevators. Unfortunately, the elevator vendor was not able to repair the drive. They suggested two alternatives: replace the drive with a new one or borrow a drive from one of the four elevators in the office buildings.  The quote for replacing the obsolete drive with the new proprietary drive had a price tag of nearly $50,000!  Swapping out the drive for one from a less-frequently-used elevator didn’t solve the problem – it just moved the problem.  There had to be a better choice available.

Looking for another option, Ken decided to call Sal Zannino, EDC’s service coordinator, to see if EDC could help. Novartis has been an EDC customer for over 25 years servicing all of the HVAC and pump systems.  “I like dealing with a local company.  Unlike at a national company, at EDC you deal with the same people every time.  I know who I’m speaking with, and who is coming out.  You get better service and it feels like a close-knit professional relationship,” said Ken. “We had never used EDC for an elevator drive, so I was not sure if they would be able to help.”

When Ken made his phone call to Sal, an EDC technician happened to be in one of Novartis’ buildings performing routine preventive maintenance (PM) service on the HVAC drives. Sal asked the EDC engineer to take a look.  Based on the engineer’s evaluation, Sal felt confident that EDC could address the elevator drive problem.

EDC is unique compared to most other service organizations in that it has two sides, a Service Division and a Systems Division.

The Systems team designs and builds full-scale automation control systems.  The 11-man Field Service Engineering Team performs site-wide VFD Preventive Maintenance programs, 24/7 on-site emergency VFD repairs, and new drive installations.  A special niche that EDC is becoming increasingly known for is the capability for providing turn-key control solutions for existing projects where new VFDs and PLC logic must seamlessly be interfaced with existing and sometimes antiquated control and mechanical systems. Both Service and Systems bring their own areas of expertise, and experience that spans decades.  Using cross-departmental collaboration where needed, EDC is a company uniquely qualified to take on virtually any control project with successful results, regardless of the difficult challenges.

Over a two-day period, EDC diagnosed the VFD, acquired the needed parts, and completed the repair. Repairs included component level Printed Circuit Board (PCB) repair, and replacement of various drive components, including capacitors.  EDC worked with the elevator manufacturer to ensure the special-order parts were obtained and delivered quickly to get the customer back in operation ASAP.   Once the repair was completed, the drive was dynamically load tested at EDC’s facility to ensure the drive ran reliably under full load conditions especially given the critical elevator application.  The drive was successfully installed, returning the elevator to normal service.

Novartis was very pleased with the repair’s cost and EDC’s effort to expedite the timeline.  The total cost of the repair was 90% less than if Novartis had replaced the drive, and downtime had been kept to a minimum through the process.

“We have been working together for 20-plus years and have established a strong professional relationship. EDC has always come through for us for all of our drive work – for maintenance, malfunctions and VFD upgrades / VFD replacements – and restored our systems accordingly. EDC has consistently given us good, cost-effective options to get our operations back online again,” said Ken.

The cost to repair the drive was a small fraction of what it would cost to replace, and the building occupants are happy to have the critical elevator back in service.  If it happens again, Novartis now knows who to call.  Until then, EDC technicians will go back to work ensuring that the hundreds of drives at Novartis’ headquarters in East Hanover continue providing maximum energy savings and reliable operation for many more years to come.

An Annealing Upgrade Cuts Waste and Improves Quality for Wire Manufacturer

A high-end wire and cable manufacturer in Connecticut had several older Syncro wire drawing lines with continuous-resistance annealing.  Some of the lines had a fixed voltage process consisting of a contactor, transformer, and manually-set voltage taps while others had variable voltage supplies.  With fixed voltage, the annealing process cannot begin until the line is at running speed. The variable-voltage design lacked a control algorithm to properly control the voltage as a function of line speed to maintain a constant elongation of the wire.  EDC upgraded the existing drives with state-of-the-art Vector AC drives and EDC’s AlphaNeal™ Annealer Control with its field proven square root and annealer control algorithm.

EDC annealing upgradeIn the continuous-resistance annealing process, the secondary of the step-down transformer is connected to the wire through a rotating sheave. The voltage potential and the low resistance of the wire cause a high current to flow through the wire, heating it up. If the wire was not passing over the sheave at a high speed, it would melt. The root mean square (RMS) power level has to increase with speed. Too little power results in hard wire and too much can burn, discolor or melt the wire. EDC has mastered the control of the annealing process solving mathematical equations in real time to provide repeatability of a quality product.   EDC is able to provide a constant anneal from near zero speed to full speed and back to zero at varying line speeds resulting in a predictable, flexible, and more resilient product for secondary processes and final sale to the customer.

EDC Systems specializes in the wire and cable industry. We have retrofitted and built new applications for hundreds of annealing sections of copper and aluminum wire drawing lines ranging from 15kVA to 850kVA. Our team looks at the customer’s entire process – from the drawing machine, the annealer, to the spooler. In addition to utilizing our control solution with an algorithm to vary the voltage to the sheaves as a function of line speed in order to maintain a constant anneal, we oversize the power section.  The system is digital and thus can be recipe-driven and controlled from an HMI and PLC. The result is a controller that will give the customer the performance and reliability that EDC is known for in the industry.

Many wire manufacturing plants around the world have wire drawing machines dating back to the 1970s. Many machines are workhorses and have proven to be reliable with a long productive life. However, technology has come a long way and machine upgrades can incorporate design improvements that can substantially improve productivity, serviceability, and the economic life of older drawing lines. EDC has retrofitted drawing lines from industry leaders like Syncro, Niehoff, SAMP, and more. Contact us today if you would like to evaluate a retrofit plan.

EDC Systems Spotlight: Shawn Leichliter

Shawn LeichliterMeet Shawn Leichliter, EDC Systems group’s dedicated engineering manager.  Shawn has been an integral part of the EDC team for a decade and a half; celebrating his 15-year anniversary with the company in May 2019.  Chosen for the spotlight by the executive team, Shawn is described as an intelligent, logical, and hard-working employee who puts in long hours when required to keep his projects on schedule.  Although normally soft spoken, Shawn becomes animated when talking about his 15-year-old son Jacob.  When the weather is nice, Shawn’s co-workers know to look for his Goldwing motorcycle parked in front of the building.

“Shawn is a pleasure to work with. His even temper, great work ethic and extraordinary intellect make him a key to our continued success,” said Chuck Dillard, vice president of EDC.

After serving our country in the US Army and earning his degree in electrical engineering, Shawn started at EDC as a service technician. After just a year he moved over to the Systems side of the business where his electrical engineering talents helped strengthen our systems team.  A fast learner, after a couple of years Shawn was promoted to engineering manager, which is his role today.  Shawn works with Chuck to manage EDC’s engineers and project assignments, as well as the panel builders in the shop.

Shawn has been intimately involved with important EDC projects that have helped grow the company.  He worked on the dual constant vulcanizing (CV) line project, one of EDC’s first multi-million-dollar projects.  The CV line makes a rubber-jacketed cable; the bare cable has up to three layers of coating extruded on it, at least one of which is a thick, insulating rubber layer which must be “cured” with heat and pressure.  After the extrusion, the cable goes into a tube where there is pressurized steam for a couple hundred feet, and then into water to cool the cable.  This project required 20 variable frequency drives (VFDs), seven human-machine interfaces (HMIs), and a large amount of remote I/O.

Shawn designed a product named Omega Wind, which is one of the few machines at EDC to be built more than once.  Ordinarily, EDC custom designs equipment tailored to the needs of a unique manufacturing situation.  Omega Wind is EDC’s name for the company’s traverse winder, a machine that winds strips of metal onto spools.  The Omega Wind carefully controls the spacing of the metal strips so that it “hits” the operator-prescribed number of turn points.  “For instance, three turn points means we will traverse across a reel, ending at 60 degrees, come back at 120 degrees, return at 180 degrees, come back again at 240 degrees, returning once again at 300 degrees and finally coming back at 0,” said Shawn. “Then it starts all over.  We have three distance turn points, one flange, and three more at the other, all evenly spaced.  The machine is all about getting the most material on a reel neatly so that when it unspools there are no issues.  We’ve probably sold more than 20 copies of the Omega Wind.”

Staying on the cutting edge of control system and automation technologies, Shawn learned the Siemens S120 drive protocol, and was the first engineer in the company to use it when he designed a highly advanced dual loop slitter.  Shawn also brought motion technology to EDC with the design of turret winders for Black Clawson Converting Machinery.

A native of northwestern New Jersey, Shawn grew up in Phillipsburg.  After high school, Shawn enlisted in the US Army, serving for 6 years as an Electronic Warfare Avionics Systems Repairer.  He was deployed to Saudi Arabia for Operations Desert Shield and Storm.  After returning, Shawn attended nearby Lehigh University and graduated with a Bachelor of Science in Electrical Engineering.  While at Lehigh, Shawn participated in ROTC and got his commission as 2nd Lieutenant in the Army Signal Corps.  After graduation he served in the Reserves as a Platoon Leader for a Tropospheric Scattering Communication station.

Shawn and his wife Lisa currently live in Blairstown, NJ with their 15-year-old son Jacob.  When not at work, Shawn runs a small business called Rail-Lynx, making infrared controls for model trains.  Shawn takes advantage of all the good weather days he can to ride his Goldwing motorcycle, often driving it to work at EDC. Shawn and Jacob enjoy their annual motorcycle road trip together, visiting fun attractions along the way.

Asked what he likes best about working at EDC, Shawn said, “I get to work on a wide variety of challenging projects in a friendly, close knit atmosphere where I know my contributions are appreciated.”

“Having a long history of working with EDC, I have to say it is obvious that EDC has really high standards when it comes to hiring service engineers. The training on the drives quickly accelerated beyond the basics as EDC’s engineers began asking questions which prompted the training to elevate to a more advanced technical session,” commented Stan. “With EDC’s large, experienced team and prompt response time, it is good to know that our customers can count on a highly-reliable resource when needed.”

In 2017, Control Techniques and Emerson’s Industrial Automation division were acquired by Nidec Corporation from Emerson Electric Company. Control Techniques is now part of the Nidec Motor Corporation.  Together their portfolio of products includes AC, DC, and servo variable speed drives as well as power conversion technologies. For more than 40 years, these brands have been trusted in many commercial and industrial markets – HVAC, elevator, manufacturing automation, and industrial applications which demand energy efficiency, such as fans, pumps and compressors.

 

Technical review by Scott Sullivan, electrical engineer at EDC

Scott SullivanControl Techniques’ representative, Stan, started off the training session by highlighting the differences between the company’s now obsolete Affinity series drive and the new H300 series drive.

The first difference of note is that the H300 has an additional programmable form C-relay output. These outputs are used when drive-specific conditions occur and an external system, such as a building management system (BMS), needs to be notified. There are several instances where these could be used, the most common being a fault output. If the drive faults, a relay will open to alert the BMS and another will close to illuminate a fault indicator. Another possible use could be for a drive started condition. In HVAC, the drive start condition can be used to open a damper, which will in turn allow the drive to run once it is fully opened. A third possible use is for a drive running condition. This can be used in HVAC for a supply and return fan. The start command for the return fan is routed through the supply fan’s running relay. This prevents the return from running unless the supply is running and automatically stops the return when the supply stops. These 3 examples are some of the many uses of relays. The inclusion of an additional relay on the H300 drive allows for greater flexibility when incorporating it into a system.

The H300 drive also has slots for expansion ports to extend the drive’s functionality. If the customer has a specific need that the “out of the box” drive can’t provide, these expansion ports can be used to meet that need. An example of this might be if a specific type of serial communication is used (i.e. BACnet, Profibus, CANopen etc.), the drive can be made to support it even if it does not natively. The expansion ports can also be used to expand the drive’s I/O capabilities. While the base drive already has an impressive suite of digital and analog I/O, if the customer requires more of one or both of these, it can be accomplished by these expansion ports.

Another upgrade of the H300 series is the inclusion of a real time clock and programmable events that utilize it. This can be used to start and stop the drive or change its output frequency at specific times of the day or week, without the aid of a BMS. While external control of a drive is commonplace, there are times that these events could be useful. An example might be a building that is still under construction. A BMS would probably be implemented when the building is completed, but in the meantime these events could be used to control water pumps and cooling fans. Examples of programmable events could be starting a drive before employees arrive in the morning and shutting down at night after they leave, or perhaps reducing a drive to a minimum speed on Friday afternoons and returning it to full speed Monday morning. These events add flexibility when choosing how to install this type of drive.

 

Our customers rely on our field service engineers to be experts on the VFD drives keeping their building and manufacturing facilities running at peak efficiency and that is exactly what we deliver. EDC is brand neutral, therefore our service engineers are continuously updating training certifications on over 40 brands of drives and PLCs.

A Custom HVAC Vibration Safety Solution for a Large Commercial Property

EDC has worked with many high-profile buildings in NYC for decades and has the necessary security clearances to access sensitive facilities.  This is a case study of one client with whom we worked to create a custom solution to a potentially very dangerous problem.

Problem:

A prominent commercial property in NYC was periodically experiencing severe vibration with the chiller fans in their HVAC system.  The vibration was sometimes so severe that the property management team was concerned that a large fan blade could come loose, creating an extreme safety hazard for employees, tenants, equipment as well as the facility.

 

Solution:

Electronic Drives & Controls implemented a custom safety system on the commercial property’s rotating equipment.  This turnkey installation automated the shutdown of a series of fans if the vibration level exceeded a specified level, ultimately preventing issues by allowing management to address the problem before allowing the fan to restart.

EDC installed sensors in the fan handling units to detect the vibration velocity of the fans.  The solution consisted of a programmable logic controller (PLC), variable frequency drive (VFD), vibration measurement hardware, network gateways, and wireless spread spectrum radios. EDC subcontracted the appropriate trades and also worked in conjunction with the building management system (BMS) provider to interface the EDC system with the BMS via Modbus TCP/IP.  Due to the physical location of the equipment, the information was transmitted over a 2.4 Ghz FM spread spectrum secure link.

Knowing there would be occasions where the fan needed to maintain continued full operation when the VFD is shut down, EDC configured a bypass to disable the VFD and communicate directly to the motor to run at full speed. This would keep the HVAC system completely functional and operational during exceptions, such as when EDC is performing preventive maintenance (PM) tasks.  Additionally, the bypass circuits were also modified to shut down and stop the motor if the vibration sensor detects vibration outside the established velocity parameters.

At EDC, we pride ourselves in helping our customers keep their facilities running at peak efficiency and safety. We are a factory authorized/factory trained service center for over 40 drive brands, and have alliances with world class hardware and software providers.
