Switching from a 2400 Controller to a 3500 is a Snap!

Thursday, July 14, 2016 6:17:00 AM America/New_York

A 3500 series controller fits perfectly in a 2400 series case. If you are interested in taking advantage of many of the FREE software features in a 3504 or 3508 controller, you don’t even need to unwire a thing. The 3508 and 2408 cases are interchangeable. There is no difference in terminal layout and the case length is identical. The 3504 and 2404 cases are also interchangeable. However, adding the 3504 instead gives you the ability to add more IO modules. The price point between the 3500 unit and the 2400 unit is very similar and we are happy to work with you in price competitive situations.

Here are some of the free features found in a 3500 series unit not found in a 2400 unit:

  • Temperature and atmosphere control in one unit
  • 50 ramp/soak programs (max of 20 in the 2400 series)
  • Logic and math function blocks
  • Automatic thermocouple burnout switching
  • Custom interface screens

 

 

Eurotherm 3216 and the Plastic Chiller Market

Monday, July 18, 2016 2:43:00 PM America/New_York

The Eurotherm 3216 has been implemented as a Chiller controller in the USA plastic market with much success.

Below is a list of the 3216 features:
1. The model 3216 has only a 90 mm depth, which allowed chiller manufacturers to have easy installation.
2. Configure of the 3216 controlleris made easy by a text display, So the user can scroll to a parameter and just a few seconds, the text display begins scrolling in marquee fashion with a description of that parameter.
3. Ordering, maintenanceand configuration have been simplified to the use of a mere 10-digit code that completely specifies the functionality and configuration.
4. Event Messages and Custom alarm can be created and loaded into the 3216.
5. The Eurotherm 3216 can replace the external timer.A timer can be used to put the unit into standby while the system is purged. Most OEMs use an external timer today, so with the 3216, a timer is not needed
6. Digital Communication is also a needed feature when selling to Chiller OEMs, and the Eurotherm 3216 meets that need.

Plastic Chiller Overview

A chiller commonly represents a small fraction of the cost of the processing equipment, yet it provides solid protection of your investment, 24-hours-a-day, and 7-days-a-week for years and years to come.The most compelling reason for a chiller in the plastics market is the protection it provides for your valuable processing equipment—such as extrusion, injection molding equipment and other applications. To increase production is another reason to use a chiller as you maintain a constant and proper cooling temperature in the equipment. A chiller will reduce the number of rejected parts while increasing the number of parts produced per hour.

A chiller is a compressor based cooling system that is similar to an air conditioner except it cools and controls the temperature of a liquid instead of air. The other main components to a chiller are a temperature controller, a recirculation pump and a reservoir. The operation and setup are simple. Fill the reservoir with fluid to be recirculated, typically water or an ethylene glycol/water mix. Install plumbing between the chiller and the application and provide power to the chiller. The controller regulates the chiller’s functions. The chiller will provide a stable flow, temperature and pressure once it has been programmed by a user. Harmful particles are kept out of the system by an internal strainer.

There are three (3) types of chillers.

An air-cooled chiller where the chillers absorb heat from process water and can be transferred to the surrounding air. Air-cooled chillers are generally used in applications where the additional heat they discharge is not a factor. They require less maintenance than water-cooled units and eliminate the need for a cooling tower and condense water pump. They generally consume approximately 10% more power than a water-cooled unit as a wet surface transfer’s heat better than a dry surface.

Second is the portable chiller, which is a liquid cooling system on casters that can be relocated from one application to another with relative ease. It can be used to cool one or more heat generating devices.

Finally, we have water-cooled chiller, which absorb heat from process water and transfer it to a separate water source such as a cooling tower, river, pond, etc. They are generally used for large capacity applications, where the heat generated by an air-cooled chiller creates a problem. Water-cooled chillers are also considered when a cooling tower is already in place, or where the customer requires optimum efficiency of power consumption. They require condenser water treatment to eliminate mineral buildup. Mineral deposits create poor heat transfer situations, which reduce the efficiency of the unit.

Summation

The Eurotherm 3216 is being used more and more to replace several interconnected devices to chillersand consolidate functions. The level of functionality, alarmingand programmability gives the user a way to create a local custom alarm strategy that can best achieve the operating safety of the machine that will help improve qualityand minimize downtime.

Tempering with Eurotherm

Tuesday, July 26, 2016 3:44:00 AM America/New_York

Tempering is used to improve the hardness and elasticity of (steel or other metal) by reheating and then cooling it.

Eurotherm has supplied hundreds of its PID temperature controllers and single-phase power control units to customers for controlling heat treatment, tempering ovens and annealing used in the manufacture of disposable razor blades, and other precision metal products.

For the blade market, obtaining a good shave requires a blade with the finest edge, which explains why quality and production consistency are fundamental requirements.

The key to achieving these important goals depends partly on the precise control of temperature in the heat treatment, annealing and tempering furnaces. Eurotherm controllers are used in these applications, as well as the injection molding process for the razor body and in special-purpose printing machines.

By providing controls like the Eurotherm 32h8 and Epack-1 PH power controls production machines achieve very the high standard of temperature accuracy and uniformity demanded by the customer. As a result, their production facilities maintain a consistent high quality, which, in turn, reduces scrap and increases productivity.

 

A current transformer input in the 3200 measures the current switched through the load. The measurement is filtered so that the on current and off currents can be separated. From this, it is possible to diagnose several load faults including partial load failure, over current and an SSR fault. Typical applications include plastic extrusion, laboratory ovens and other applications where early indication of heater failure can save energy and rework costs.

Recipe Function for 3000 Series Eurotherm Instruments like in the Model 3204

Thursday, August 18, 2016 1:09:00 AM America/New_York

The 3000 recipe function is unique one in many controllers of this class. Recipes can be stored under a user-defined name to recall a number of parameter settings. These settings may include operating variables or configuration parameters, providing a very powerful means of altering the setup of a controller in a single operation. Recipes may be recalled either from the HMI, over the communications link, or using digital inputs.
