Traditional pump-control systems are an assemblage of stand-alone components, often from different manufacturers. Getting all of these pieces to function together can be a daunting task requiring expertise in pumps, controls, and communications. Synthesis™ eliminates coordination hassles by seamlessly combining variable-speed motor-control, PID process control, and soft logic into a streamlined solution. Simply enter a setpoint or connect the controller to a building automation system—no other controllers are required. The entire system occupies but a fraction of the space required by component systems. Setup and service are simplified, too, since there’s no more finger-pointing among vendors.
From single pumps to complex sequenced systems, Synthesis™ provides intelligent control. It knows how to get the most out of each pump, yet treats the system as a whole to maximize performance, efficiency, and pump life. Driven by a powerful digital signal processor (DSP) and UNICO’s patented digital current regulator, the all-digital controller has the high-speed computational muscle necessary for precise AC motor and integrated process control. The flux vector technology behind the Synthesis™ controller provides the most responsive pump system available. Features such as smart pump cycling and pump synchronization yield smooth control while minimizing wear and tear on the system.
Synthesis™ takes the time and guesswork out of setup by tuning itself to the motor, the pump, and the pumping system. After initially being connected to the process through the motor, the controller will automatically interrogate the system using small bursts of current to identify key process variables. This information is used by the vector and PID controls to provide optimal performance. The unit is effortlessly tuned within minutes.
Synthesis™ is the only pump controller that takes advantage of individual pump curves to ensure that a pump continuously operates at peak efficiency. UNICO’s Pumping System Intelligence™ (PSI) technology mathematically models pump operation to achieve optimal performance, efficiency, and pump life. Enter a few points from the pump’s published curve, and the controller does the rest, dynamically calculating key performance variables to determine the most efficient staging. The pump will operate as close to the best efficiency point (BEP) as possible for the given conditions, precisely delivering the demanded capacity without wasting energy.
Using the motor as a sensor, Synthesis™ continuously monitors system performance for irregularities in head pressure or flow and for conditions that could damage the pumping equipment. By knowing a pump’s curve, the controller inherently protects against end-of-curve, cavitation, deadheading, and minimum flow conditions by sensing them ahead of time and reacting to avoid them altogether. Should a problem occur, the system provides the appropriate warnings or interlocks to shut the system down.
A touch-sensitive operator interface simplifies start-up and operation. Users are walked through the commissioning process step by step. Once the system is running, monitoring screens graphically portray system operation, and users can select which information to display. A fault display and on-board interactive diagnostics provide troubleshooting assistance in the event of a problem.
Single-phase systems can be provided that permit ordinary three-phase motors to be used in remote locations where three-phase voltage is unavailable.
Synthesis™ system enclosures can meet the most stringent environmental requirements, including outdoor and wash-down duty. Standard NEMA 1 or optional NEMA 4, 3R, and 12 packaging is available. Units are engineered to meet NEC standards and carry the UL and C-UL labels. Each system is extensively tested and burned-in prior to shipment.
