Coming Soon: Fail-Safe Loop Controls

Coiltek has been creating ultrasonic loop control systems for over 30 years, and we have continued to update and innovate within this niche. Even with all of our efforts to create a reliable product, sometimes things still go wrong. Up till now, without a backup, that meant a down line until a replacement could be obtained.

Not anymore. Soon we will be introducing a product with two kinds of loop controls integrated into a single system, which we create a self-regulating, fail-safe device to keep a line up-and-running even when one half of the system is down.

Stay tuned for more details about this exciting new development!

Replacement Parts from Coiltek®

A line is a big investment, and when it goes down, you loose money. That’s why we strive to make products that stand the test of time. Many of our boards have lasted in the field for over 15 years. In fact we have seen many boards sent in for repair that are over 20 years old, and many of those can actually be repaired.

For those times when a repair just isn’t fast enough, we also supply replacement boards. We keep all of our boards and cables in stock at all times so that we can get you up and running again ASAP.

We also design all our equipment to be backwards compatible. That means that even if your loop control is 20 years old, if the stand is still in tact, you can just replace the boards with our new CB-5501M control board and CB-5101R-1 ranging card, and bring your unit back to life.

If you have any questions about replacement boards or repairs, or to request an RMA number for your repair, please contact us. For more info on Coiltek, our high-quality, American made loop control systems, check out our main site.

Introducing the new CS-6200 no-touch loop control

Our popular Coiltek CS-6100 line of non-contact loop controls has finally become obsolete, but don’t fret; we have a new low cost, highly reliable, American-made no-touch loop control system to take its place.

Introducing the new CS-6200 ultrasonic loop control system from Coiltek. This exciting new product line features much of the same technology found in our industry standard CS-5000 V2 line of non-contacting loop controls, and has many of the same capabilities: Instant push-button calibration, on-board storage for up to 8 programs, and optional remote access to up to 3 preset programs, plus much more!

If you would like more information about this product line and it’s uses, such as in the plastic tubing industry, please check out our brochure. If you have further questions or would like up-to-date pricing, please contact us

Sneak Peak of the All New CS-6202 Loop Control

The next step in the evolution of ultrasonic controls is here: The CS-6202 from Coiltek. This no-touch ultrasonic loop control system is small (about 4′ tall), but mighty. It is sensitive enough to “see” even the thinnest stocks and equipped with all the same standard features you’ve come to expect from Coiltek’s industry standard sonic loop controls: On-board storage for up to 8 distinct programs, 0-10 VDC  and 4-20 mA output, easy remote set-up via computer with on-board USB port, and instant push button manual calibration. The new CS-6202 also comes with a potentiometer on the exterior of the electrical enclosure, for easy sensitivity adjustments.

Ideal applications for this product are wire and plastic tubing, such as for medical and automotive applications. For more information on this or any other Coiltek product, please don’t hesitate to contact usCS-6202 edited 1.

Non-Contact Loop Controls

Our Coiltek loop controls are non-contact loop controls. While most manufacturers of ultrasonic loop control systems have only one line of no-touch loop controls which use out-dated technology, we have two distinct lines of completely upgraded ultrasonic loop control systems.

The new Coiltek CS-5000 V2 and CS-6200 lines of non-contacting loop control systems are powerful and reliable. Our updated technology allows for on-board storage of preset programs, USB connected remote programming via computer, and instantaneous manual calibration.

At Coiltek we are always looking for new applications. With this in mind, we are creating a model of the low-cost, non-contacting CS-6200 line, the CS-6202, for use specifically within plastic tubing manufacturing.

If you have an application you believe could benefit from our ultrasonic distance sensing technology, please contact us. With great customer service and expert technical and engineering know-how, we can answer every question you may have and even tailor our products to suit your needs. Give us a call today.

The 3CPO Accessory for Coiltek Loop Control Systems

The 3CPO option allows for easy-access to multiple stored programs.

Coiltek’s CS-5000 ultrasonic sensor has always had the capability of storing multiple loop control parameters.  The 3CPO option makes it easy for press operators to quickly switch to the appropriate loop control algorithm to run the job.

Why would you need different loop control parameters?  Here a few examples of press jobs that beg special treatment.

  • Long Feed Progressions.  If each press cycle pulls most of the slack from the loop, your loop control algorithm should include offset.  With offset, the control signal from the CS-5000 jumps from zero volts to some percentage of full scale output.  Figure 1 shows a comparison of a standard analog output with a 30% offset output.  With offset, the feed equipment (decoiler or straightener/flattener) gets a substantial move signal before too much loop is depleted.  This head start overcomes the  inertia of the equipment giving it more of a chance to match the press throughput.   With offset set properly, the feed device will run more smoothly.  Here’s why: The loop will swing up and down dramatically with each stroke of the press.  This is an unavoidable. The loop control will sense the large fluctuation.  Note that with offset, the output signal over the control range presents a gentler slope than a pure 1:1 analog output.  Provided the loop stays within the desired control range, the drive that the CS-5000 controls will exhibit far less “wow” (variation in speed with each press stroke).  Offset works best with constant speed devices like straighteners or nip-pullers than with decoilers.   The dwindling radius of the coil represents a constantly changing system gain, which can make the offset characteristics difficult to dial in.
  • Thick stocks.  In a given looping area, thin stocks ‘drape’ better than thick stocks.  In fact, if there is insufficient looping distance, thick stocks cannot be pushed all the way to the floor without imposing set (curvature) in the material.  Where a straightener/flattener is used to remove coil-set, it’s hardly good practice to re-institute it in the loop.  It’s critical then, if you run different stock thicknesses through the same press, that you set different control ranges to adapt to material thickness.  A preset program associated with a particular stock thickness  lets you control the radius of curvature in the loop so that stock bending stress is kept below yield.
  • Short Feed Progressions.  When a straightener, designed to keep up with high press throughputs, is presented with a very short feed progression or slow press SPMs, a standard loop control algorithm  can cause problems.  The straightener will grind along at a small fraction of its rated speed. Without ventilation from its internal fan the motor overheats.  At best, the thermal cutouts snap, and the straightener’s down.  Usually, the motors just burn up.  The CS-5000’s control relay lets you program an ON-OFF system with hysteresis  Using the control relay, the straightener turns on when the loop rises to a predetermined height, then stops when the loop drops below a certain level (see figure below).  This way the straightener is ON at a reasonable speed for a while, then rests. In the figure below the diagonal arrows in the time graph indicate whether the loop is depleting (arrows point UP) or re-filling (arrows point DOWN).

This algorithm is a little more complicated to program and wire.  If your line requires this feature, refer to our white paper entitled Accessing ON-OFF Control Within the 3CPO Option.

Programming the CS-5000 series controls for multiple program presets can be performed manually with the on-board DIP switches.  Full functionality including programming OFFSET or the Control Relay must be performed using Coiltek’s CSWin32 software.  It’s a free download from this website.  The 3 CPO option is available pre-installed on our CS-5000, CS-5100 or even our CS-6100 series controls.  It is also sold as a simple-to-install kit.

Coiltek Hammerhead Accessory

At Coiltek we’re always trying to find innovative solutions to industrial problems involving loop controls. One such innovation is our Hammerhead accessory for the CS-5000 series of ultrasonic loop controls.

The only one of its kind, the Hammerhead features 3 ultrasonic elements which, when the kit is attached to the boom of the unit, are seated in a line parallel to the stock the unit is sensing. This innovative design triples the sensing area of the CS-5000 in order to sense stock continuously even when the bottom of the loop moves vertically throughout the process.

To learn more about the Hammerhead Accessory, as well as our other offerings, please visit our Products page. You can also learn more about our loop control systems by checking out the brochures in the Downloads section of our site. If you should have any questions or would like to request a quote, please don’t hesitate to call us or drop us a line using the widget on our Contact Us page.

Coiltek Loop Controls: Durability and Repairs

Although we’ve made forays into winding and converting equipment, Coiltek’s mainstay product is the ultrasonic loop control. Our loop control systems are no-touch loop controls that use ultrasonic sound waves to sense distance and control the output of a straightener or decoiler. Coiltek loop controls are American made in the great state of Ohio. The stands for our loop controls are made of steel tubing, lending strength and durability that stands the test of time. In fact, many Coiltek loop controls have been in the field for over ten years and still function perfectly.

Should your Coiltek loop control ever malfunction, don’t hesitate to give us a call. We stand behind our loop control systems for the full length of the product’s life – no matter how long that may be. Unlike some companies that charge for a service plan, over the phone technical support is always free for Coiltek products.

If the problem cannot be fixed over the phone, we offer a full line of replacement parts to get your loop control – and your line – up and running again as soon as possible. Our loop controls can also almost always be repaired. If your loop control needs to be repaired, simply remove the electronic boards, place them in a static safe bag and call us for an RMA number and shipping instructions.

We hope that you will have many years of perfect service from your Coiltek loop control, but if you don’t, we are always available to help make sure that you can get up and running again soon.
