MAIN CHARACTERISTICS OF FREQUENCY CONVERTERS USED IN THE PHV BOOSTER SETS

The PHV series booster sets use a Hydrovar® variable frequency drive, an automatic device that adjusts the speed of the electric pump in order to maintain constant pressure in the system.

Converters with power up to 30 HP can be mounted directly on to the motor. Models with over 30 HP power, are designed for wall mounting only. The pressure is measured by a pressure transmitter which uses a standard 4..20 mA current signal. The system pressure value can be read on the converter’s display. A simple user interface allows you to set the desired pressure value for optimal adjustment, as well as to view the operating data, such as the hours of operation and any alarms triggered. Included diagnostic menu to view temperature, current and voltage values facilitates diagnostics and failure analisys. Indicator lights signal power status, pump running and malfunctions.

Modular Hydrovar, Bare Unit

A password is required to access sensitive settings that allow you to program the Hydrovar in order to adapt it to any control requirements, such as flow resistance compensation, external control, periodic testing and so on. When more than one pump is used, the converters exchange information with each other through an RS485 serial line which can connect up to 8 Hydrovar devices plus one external unit for remote control. The Pump-link and Pump-watcher dedicated systems, connected to the Hydrovar®, enable remote control through a traditional telephone line or mobile telephony. A serial port available as standard up to 15 HP allows you to control the Hydrovar® converters from a Modbus® field serial bus line.

The converter is equipped with two potential-free relays which can

 

be used for remote signalling of pump running and malfunction

 

status, plus a programmable voltage analogue output for signalling

 

the frequency or pressure. Standard version with two sensor inputs

 

for implementing of two actual values signals within one system (min/

 

max, difference) or for a second sensor for safety reasons. Specific

 

digital inputs are used for protection against water failure, motor

 

overtemperature, as well as for external enable signal and remote

 

control. The converter also incorporates a dry running protection

 

function via an adjustable minimum pressure threshold.
