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.

The CTAC-2 “Cone of Silence” from Coiltek

At Coiltek we try to anticipate any issues that our customers may have and create a solution. One such issue when using an ultrasonic loop control system is off-axis ultrasonic interference. This interference can be caused by things such as nearby blow-off hoses and can cause a unit to behave in strange ways.

Luckily we have devised a simple solution to issues of ultrasonic interference: The CTAC-2, nicknamed the “Cone of Silence”, the CTAC-2 is a cast aluminum cone lined with acoustic foam, which slides easily over the boom of your existing unit and absorbs any off-axis interference.

If you have any questions or comments on the CTAC-2 or any of our high quality no-touch loop control systems or accessories, please don’t hesitate to 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.

Even more variety in the Coiltek lineup!

The Coiltek lineup is growing! We are pleased to announce that soon we will be unveiling a new no-touch sonic loop control system specifically geared towards working with the smallest stock, such as medical tubing. This ultra-sensitive unit will come with a stand, but be smaller and lighter weight than our CS-5000 series.

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.

Coiltek Loop Controls

Coiltek makes ultrasonic loop controls, which are sometimes known as sonic loop controls, sonar loop controls, and no-touch loop controls. Our founder invented the concept of using ultrasonic frequencies to sense and control the height of a loop during processes such as stamping, winding, rewinding, and extrusion and our loop controls have been the industry standard ever since.

Advantages of Coiltek Ultrasonic Loop Controls

The advantages of Coiltek loop control systems are plentiful, but today we will focus on three major advantages: No-touch feeding control, durability, and programability.

Coiltek makes the industry standard ultrasonic loop control systems. Our CS-6200 series of low-cost loop controls and our popular CS-5000 series of ultrasonic loop controls provide a 0-10v output to control the feeding of a straightener or decoiler, allowing for consistent feeding without touching the stock. This is an advantage especially for stocks that move a lot during feeding, such as wide stocks, and for non-conductive stock, such as plastic tubing or extruded rubber.

Coiltek products stand the test of time and it is not unusual to see a unit in a plant that is more than a decade old. In fact, our shop regularly receives inquiries about updating working systems built over 15 years ago. We stand behind our product and offer free lifetime phone support for every product we make. We also repair our old boards to save our customers money. All of our new products are backwards compatible, meaning that any time you decide to update your system, you will be able to find parts that work.

Finally, our Coiltek units make switching between stocks and their respective programs easy with on-board storage of up to 7 preset programs. We even offer an option to make 3 of those presets remotely accessible, called the 3CPO.

If you have any questions about what the durability, flexibility, and adaptability of Coiltek loop controls can do for your business, please contact us.

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.
