Pedrollo PRO-DG Wall Mounted Inverter

Installation And Use 

PRO-DG is an inverter-based electronic control device compatible with both surface and submersible pumps, with motor powers of up to 15 HP. It is specifically engineered for professional applications in water supply, distribution, and transportation across commercial, industrial, and agricultur- al sectors. Additionally, PRO-DG seamlessly integrates with all types of pressurization systems, including existing setups, ensuring enhanced comfort, prolonged system lifespan, and significant energy savings. PRO-DG protects the pump from:

•  Dry running
•  Overcurrent
•  Overheating
•  Lack of phases in connections (for TT versions)  

Product Description

PRO-DG is a frequency inverter to be installed on the wall using the WALL MOUNT SUPPORT installation kit , which includes a ventilation system to induce forced cooling of the electronic components. Connected to an appropriate pressure sensor, PRO-DG ad- justs the motor rotation speed to be varied according to wa- ter demand and maintains a constant pressure in the system for greater comfort and energy savings.

PRO-DG features include: – RS485 communication facilitates the connection of up to 8 devices and the creation of pumping groups comprising multiple pumps of the same type. – a display and keypad enable straightforward and intuitive configuration of basic operating parameters through a start-up wizard consisting of a few simple steps.

Key Features 

• Easy programming and adjustment
• Constant pressure in the system
• Energy Conservation
• Reduced noise operation
• Compatible with all pumps on the market
• Communication of up to eight devices
• Intelligent intervention management in case of anomalies

Optional A Richiesta

  An expansion board can be connected to the MT2-11 and TT3-11 models (standard in the TT3-30 model), providing the following capabilities:

– connect to monitoring systems with ModBus connection;

– take a differential pressure reading by connecting a sec- ond pressure transducer.

User Interface

The keypad simplifies the process of accessing and navigating con- figuration menus, enabling the adjustment, and monitoring of various operational parameters, including system pressure, operating frequency, absorbed current, and alarm messages. LED indicators provide quick insights into the pump's operational status at a glance.
