DCS NORD Condition Monitoring for Predictive Maintenance Monitors 1 400 

NORD’s condition monitoring solution focuses on status-based maintenance to increase service life of components and machines, predict undesirable operating conditions, and reduce unplanned downtimes, service costs, and material costs. It uses sensors and drive parameters to provide status-based maintenance. 

Condition monitoring for predictive maintenance is a drive solution developed by NORD that focuses on status-oriented maintenance rather than traditional time-based maintenance. Status and drive data are recorded periodically or continuously via the PLC output parameters and can be viewed or saved to a local dashboard via an Industrial Ethernet protocol such as EtherNet/IP. The collected data is analyzed and used to detect any suboptimal operating conditions so that machines and systems can be proactively maintained, and unplanned downtimes can be avoided. Condition monitoring increases the service life of components, machines, and the overall system effectiveness. It also reduces service and material costs.

A gear unit with old oil can lead to wear and tear of components and cause a drive to lose performance and efficiency. NORD’s SMART OIL CHANGE function (SOC) uses virtual sensors of the integrated PLC with gear unit parameters and specific operational parameters to calculate the optimal time to change the oil to keep gearboxes in pristine condition and running longer. In addition to digital and analog sensors that monitor internal values, the drives can also evaluate external conditions with temperature and vibration sensors. Together, these sensors and sensor data play an important role in condition monitoring and provide a system that is IIoT and Industry 4.0 READY!

Along with the SOC function, condition monitoring (CM) has three functional solutions: CM1, CM2, and CM3. These functions are scalable to production size and include tasks such as drive monitoring, drive control, and process control. At the first level, CM1 performs drive monitoring and data transfer via an Ethernet interface from the VFD to the local Industrial PC (IPC). CM2 uses the integrated PLC within the VFD for threshold[1]based evaluation of external sensors and drive parameters. Finally, CM3 provides visualization of the drive data through a local dashboard. The data can be viewed by comparing two parameters between several drives, and through reports displaying pending and acknowledged faults. Data from the past can also easily and quickly be displayed via a calendar function.

Each drive uses its integrated PLC for processing of measured values and has an external signal column that visually alerts to its condition status with the colors green, yellow, and red. Green indicates that everything is working properly and there are no warnings or errors. When yellow is showing, there is a warning present in the VFD and at least one of the four measurements has exceeded the warning threshold. Red designates that the drive has switched to the error state and at least one of the four measurements has exceeded the alarm limit. These signals are a quick indication of drive status and allow faults to be addressed in a timely manner - avoiding possible damage to the drive. All warning and alarm messages are also displayed on the external dashboard and can be acknowledged using a reset button. In general, the functions of condition monitoring are fixed, however users can adjust the alarm threshold values to suit their specific application needs.

By detecting undesired operating conditions early using drive sensors and parameters, condition monitoring allows faults to be addressed immediately - saving the drive and components from damage and optimizing operational safety. Using status-based maintenance rather than time-based maintenance means that drives run more efficiently, and the service life of components and machines is extended. Status-based maintenance also means that downtimes can be planned, resulting in a more organized functional system and a decrease in costly unplanned downtimes. NORD’s condition monitoring solution provides valuable data analysis for predictive maintenance.

DCS Siemens SIRIUS Controls Ensures Cold Beer 1 400

Breweries are known for transforming malt, hops, and yeast into beer in gleaming brewing kettles and large fermentation tanks linked by numerous pipes.

Over the centuries, the equipment for mashing, lautering, boiling, and fermenting beer according to carefully guarded recipes has been steadily perfected.

 

The chiller is the heart of the brewery

One of the most important parts of the brewery, and perhaps the least visible, is the chiller. The fermentation temperature of the beer is crucial, which means that the heat generated by the yeast fermentation must be carefully controlled by the chiller.

If the beer ferments at too high a temperature, the yeast can produce a variety of undesirable aromas that ruin the beer.

According to Justin Thomas, President of G&D Chillers, based in Oregon

"The chiller is the heart of the brewery. Owners invest not only a lot of money in the brewery and brewing equipment, but also a great deal of time in the production of beer. But if the chiller fails, all that goes out the window."

Partnerships to keep pace with growth

Thomas says that growth at G&D Chillers has been exponential over the past 15 years. To continue this rate of success, the company had to look for new ways to meet customer demands for reliable, state-of-the-art chiller options.

For example, G&D Chillers recently teamed up with Siemens and the global distribution and supply chain solutions company WESCO to meet these needs and stay ahead of the competition. "We're still a small manufacturing company, but big enough to produce some technically advanced equipment," says Thomas. "We've always been service-oriented and always stood by our equipment, no matter what the problem. We get the same kind of support and service from Siemens that we give to our own customers."
