■ Connection to the sensor, located wherever in the piping you want to maintain the desired constant physical dimension (pressure, flow, liquid temperature, etc.). ■ Set device to configure the pump to the system and the desired performance. Upon the initial startup of the device, you directly access the guided initial configuration process via the keyboard or app, allowing for a quick yet comprehensive programming of the inverter. Additional parameters can then be configured based on three levels of access: ■ End user level. The only level which can be accessed without a password. It allows...

IT CAN BE INSTALLED DIRECTLY ON THE MOTOR OR DIRECTLY TO THE WALL WITH A SUPPLIED INSTALLATION KIT MOTOR KIT The inverter is cooled by the motor cooling fan. Motor kit consists of 4 special clamps (or flange adapter) to secure the device to the motor fan cover (or motor feet). NEW MOTOR FASTENING HOOKS The fastening hooks on the motor fan cover have been completely redesigned to be perfectly compatible with the majority of motor types. WALL KIT The unit is cooled by an external cooling fan attached to the inverter radiator. A special metal bracket is supplied for device to be mounted on the wall....

UNIVERSAL CONTROL The various models comprising the range differ from each other in terms of size and power electronics, while the control board, keyboard, and firmware remain the same. In this way, once you have learned how to use and program one model, installing the other models becomes simple and immediate, regardless of their power. DESIGNED TO LAST The technological solutions adopted in electronic and mechanical design are the result of extensive experience gained over the years with thousands of devices in various application areas. To ensure greater durability and performance even at...

EFFICIENCY AT MAXIMUM LEVELS The use of state-of-the-art power electronic components and the adoption of film capacitors allow the achievement of maximum levels of efficiency, both in terms of electrical consumption and harmonic mitigation. In fact, all models belong to the efficiency class IE2 according to the EN61800-9-2 standard. AUTOMATIC ADAPTATION In addition to protecting the motor from overvoltages and overloads, the inverter is capable of automatically adapting its performance to power and environmental conditions. This means that if the ambient temperature or the current absorbed by...

Software implemented in each drive of VASCO - VAriable Speed COntroller range is the result of a long-time experience in solving customer requests and constantly following new drive applications. MINIMUM MOTOR FREQUENCY This parameter prevents motor operation below a certain frequency, thus avoiding damage to the thrust bearing of the submersible motors. PI Control Max motor freq. Ramp down time MINIMUM MOTOR FREQUENCY RAMP Motor can accelerate from 0 to the minimum motor frequency following a very fast ramp and then go through a slower ramp. Ramp up time Stop delay Control ramp Min motor freq....

LOSS COMPENSATION PROPORTIONAL TO THE WATER FLOW If the pressure sensor is placed near the pump, with the increase in flow the pressure value at the furthest outlet is lower than the set pressure. It is possible to vary the set pressure in proportion to the frequency to compensate pressure loss in the pipes. 4 bar Compensation (1 bar) Set value (3 bar) Min. mot. freq. DRY RUN ALARM THROUGH ELECTRICAL PARAMETER READING. When the pump operates in a dry run condition, the power factor value (cosphi) or the current absorbed by the motor falls below a configurable critical value, and the inverter...

PERIODIC START ANTI-BLOCKING To prevent the blocking of mechanical and hydraulic parts of the pumping system, it is possible to set the periodic start of the motor after a certain period of inactivity. AUXILIARY CONTROL MODE In some cases, it is necessary to switch from the main control mode (e.g., constant pressure) to the auxiliary mode (e.g., fixed frequency). In such cases, it is sufficient to program the desired auxiliary control mode and act on the dedicated digital input. PIPE FILLING RAMP When the hydraulic system is empty, starting the pump, even under pressure control, could cause water...

PREDICTIVE ANALYSIS AND REMOTE CONTROL Through predictive analysis performed by the device during operation, it is possible to intervene before a problem occurs, minimizing intervention and repair costs. If the device is connected to the Internet, warning or alarm notifications can be sent via email to the concerned users. For this purpose, a quick configuration from the remo.nastec.eu portal is sufficient. REMO, the revolutionary Nastec system for remote controlling devices. To implement the REMO control system ■ Install an Android or iOS smartphone nearby Nastec device you wish to control....

In addition to constant pressure control, VASCO - VAriable Speed COntroller allows other control modes such as fixed frequency, constant flow, constant temperature. CONSTANT PRESSURE The inverter controls the pump speed to maintain constant pressure at a set point independent of the water demand in the system. In a hydraulic system equipped with inverter, the standard pressure tank is replaced by a smaller tank which functions to maintain the set pressure in the system when the pump is stopped. Inverter Pump No return valve Pressure tank 5 Valve 6 Pressure transducer 7 Power supply INTERNAL OR...
