PUMPS AND FANS ON/OFF MONITORING WHITE PAPER

When knowing the motor is running makes the difference.

Turning a motor ON doesn’t automatically mean that it is running. There may be failures around and the control system (a PLC or a Building Management System - BMS) must be informed that the action is not happening. The usual question is “How valuable is it to know this early?”, to be able to trigger actions and deploy countermeasures. We’ll address the most important aspects and propose some solutions to increase the value of the performance in applications such as water circulation pumps and fans.

INDUCTION MOTOR ENERGY EFFICIENCY REGULATIONS WHITE PAPER

Benefits of using soft starters with high efficiency motors.

Industrial electric motors account for roughly 50% of the worldwide power consumption. Worldwide initiatives have been put in place by different countries in relation to the efficiency improvement of electric motors. Higher quality and more efficient motors have the potential to reduce energy use significantly. The challenge with higher efficiency induction motors (IE 3, IE 4 classes) is that of the higher starting current. Such current magnitudes may cause undesirable effects on the voltage network and may also cause protection circuits to trip. This paper covers the various challenges posed by high efficiency motors and how soft starters as well as variable frequency drives can help users overcome such issues.

THE NEW NRG DIGITAL SOLID STATE RELAYS WITH PHASE ANGLE AND SOFT START SWITCHING

Increased versatility with the addition of new switching capabilities.

Lainate, May 2021 - Carlo Gavazzi Automation, the international electronics group with activities in the design, manufacturing, and marketing of electronic equipment, today presents an addition to the family of NRG digital solid state relays – the NRG with phase angle and soft start switching.

The digital revolution of industrial automation is upon us. Industry specialists are focusing on IIoT systems to take the leap forward.

The NRG system of digital solid state relays fits right into this digital thread of information with the availability of monitoring and diagnostic functions on top of switching capabilities via a communication interface. Initially released in Modbus RTU, the NRG is also available in the two largest Ethernet protocols on the market: PROFINET and EtherNet/IP.

This new range of NRG solid state relays will expand the switching capabilities of the NRG system through the addition of phase angle and soft start switching. These switching modes are mainly targeted at applications utilising Short Wave Infrared heaters, which are becoming very popular in the industry. Phase angle is used to achieve a finer resolution of power for specific applications and the soft starting function limits the inrush current at start-up which can be detrimental to the heater’s lifetime.

“The NRG is the solid state relay system ready for Industry 4.0”, Dora Lee Borg International Product Specialist says. “With this new range of solid state relays, Carlo Gavazzi will increase the flexibility of the NRG system of digital solid state relays to be integrated into a wider variety of applications. With all the switching modes and control settings available via the communication interface, setting up the system according to application requirements can be done in a matter of minutes.”

Developed in our competence centre in Malta, the NRG has been designed to suit any heating application where precise temperature control is crucial to guarantee the quality of the end product and where unplanned machine stoppages can result in considerable losses of revenue. Typical applications are plastic injection machines, packaging machines, semiconductor manufacturing and glass tempering machines.

Main technical features
• NRG controller with PROFINET, EtherNET/IP or Modbus RTU interface
• Max. 32 NRG solid state relays (RG..CM..N) in 1 NRG bus chain
• NRG solid state relays go up to 660 VAC 65 A, 90 A (versions without heatsink)
• Selectable switching modes: ON/OFF, Burst, Advanced Full Cycle, Distributed Full Cycle, Phase Angle and Soft Start
• Predictive failure detection with Load deviation indication
• Read-outs: Current, Voltage, Power, Energy consumption kWh, Load and SSR Running hours
• Malfunction detection: Mains loss, Load loss, SSR short circuit, SSR over-temperature, Voltage/Current/Frequency out-of-range

RSBT 45MM: THE COMPACT SELF-LEARNING SOFT STARTER FOR 3-PHASE SCROLL COMPRESSORS UP TO 15 kW

New features further enhance the product’s installation flexibility through field replaceable auxiliary relays and Modbus modules as well as multi-voltage operation.

Lainate, May 2021 - Carlo Gavazzi Automation, the international electronics group with activities in the design, manufacture and marketing of electronic equipment, today presents its new series of soft starters.

Energy efficiency regulations in buildings are driving the need for more intelligent HVAC systems. The integration of such a system within a building management system (BMS) triggers the possibility to get more information down to component level.

As the compressor is typically the largest energy consumer in a heat pump or chiller, measuring the energy in real time gives the possibility to monitor the overall system efficiency. Apart from this, the set of data that the RSBT Modbus can measure also facilitates after sales activities such as quicker fault finding. Moreover we also offer the possibility to modify a limited set of parameters thereby giving our customers further flexibility to customise the product for specific applications.

Field replaceable auxiliary and Modbus modules are now possible to be set up on the same RSBT, which provides much more flexibility. All these features are offered in one of the most compact soft starters on the market.

“Our soft starter configuration software (SCS) allows users to visualise in a more graphical way the variables that are measured by the RSBT. Optional modules are now fully interchangeable and can be bought as separate components for total flexibility when it comes to installation. Either of the modules can be plugged into the front connector of a RSBT to enhance the product’s functionality,” Brian Gauci International Product Specialist says. “It is our intention to strengthen our products range, offering more flexible and advanced products with several intelligent features suitable for smart HVAC systems.”

Developed in our competence centre in Malta, this soft starters series has been designed to provide our customers with a more advanced product offering in the HVAC market segment, primarily for the Heat pumps and commercial refrigeration cabinets applications.

Main technical features
• Self-learning algorithm: optimises motor starts in every condition without the need of any user settings
• Energy saving through internal bypass relays
• Robust design allows up to 12 starts per hour
• A unique solution providing multiple data so that user may remove additional components from the electrical panel
• Intuitive user interface for device setup and visualisation of real-time parameters, soft starter status, alarms and parameter modification
• The auxiliary relay and Modbus module can be used interchangeably on the same device providing higher flexibility
• QR Code for a troubleshooting guide
