Installation and Set Up

We are always trying to make your day easier, and that’s why we have a lot of our information readily available on our website. If you ever need to reference the set up your ultrasonic non-contact loop control, the procedure for either our older style CB-5101M board or the NEW CB-5501M board, you can find that information here.

You can also find information on installing our 3CPO and H14 Hammerhead accessories for the CS-5000 and CS-5100 series non-contact loop controls. These step-by-step instructions even include pictures to ensure ease of set up.

If you have any questions about installing or setting up your unit, please let us know. You can find our contact information here.

CS-5000-54XX

The standard Coiltek loop control model, the CS-5000, comes in three different stand heights. Last time I discussed the benefits of the CS-5000-15XX, which comes with a 15″ tall stand and a customer-dictated boom length (represented by the XX in the name). This time, we will talk about the next size up, the CS-5000-54XX.

The CS-5000-54XX, as the name suggests, features a 54″ tall stand and a variable boom length, which is dictated by customer need. If, for instance, you need to position your loop control further away from the line or have wide stock, choose a longer boom. If you want your stand closer to your line, choose a shorter boom. When ordering a stand, the XX in the part number can be replaced by the chosen boom length. You can choose between many boom lengths, from 11″ to 48″. The most popular combination boom length for the 54″ tall stand is the 11″ boom, otherwise known as a CS-5000-5411.

The CS-5000-54XX can be used over pits, if necessary, and with a variety of different materials, from steel to plastic tubing. This reliable, adaptable system can also be used with a world of accessories to enhance its performance, such as the CTAC-2 sound isolation cone, the Hammerhead multiple transducer assembly, and the 3CPO, which grants remote access to 3 preset programs.

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.
