Product Usage Instructions

Installation:

To install the PRO-DG wall-mounted inverter, follow these steps:

1. Use the WALL MOUNT SUPPORT installation kit for wall mounting.
2. Connect the inverter to an appropriate pressure sensor.
3. Ensure proper ventilation for forced cooling of electronic components.

Programming and Adjustment

The keypad on the electrical panel simplifies programming and adjustment of operational parameters like system pressure, operating frequency, current, and alarms. LED indicators provide quick insights into the pump’s status.

Troubleshooting and Maintenance:

If the PRO-DG detects anomalies like dry running, overcurrent, overheating, lack of phases, or motor faults, it intelligently manages interventions. Regularly check for proper functioning and cleanliness of components to ensure optimal performance.

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 connec-tion;
  • take a differential pressure reading by connecting a sec-ond pressure transducer.
