ACTIVE DRIVER PLUS M/M 1,1 frequency converter - action DAB.ACTIVE DRIVER PLUS FM

Product detailed description

The ACTIVE DRIVER PLUS frequency converter is commonly used in residential and commercial buildings to regulate pump performance in closed-loop heating and circulation systems. Installers typically integrate this unit with centrifugal pumps to ensure stable pressure delivery despite fluctuating demand. This system is particularly useful in applications where energy efficiency and precision control are required, such as in underfloor heating circuits or domestic hot water installations. Proper setup ensures optimal pump performance and minimises wear due to unnecessary overloading.

During installation, the device is mounted near the pump and connected to the power supply and control circuitry. Technicians must verify that all connections align with the pump’s specifications and that the control wiring is correctly configured. Common errors include incorrect phase sequence or improper grounding, which can lead to erratic operation or damage to the electronics. The user interface allows for real-time monitoring of pressure levels, fault messages, and operational adjustments without requiring advanced diagnostic tools.

Technical parameters

Installation and connection

Begin by securing the frequency converter in a dry, accessible location close to the pump. Connect the input power supply using the designated terminals, ensuring correct phase alignment. Verify that the motor’s cable connections match the terminal labels and that all protective earth connections are intact. When connecting the pressure sensor or feedback loop, ensure it is positioned at a point representative of the system’s load. After installation, perform a startup test to confirm that the pump responds correctly to speed adjustments and that the interface displays accurate readings. Avoid running the pump dry or connecting incompatible motor types to prevent damage.

Compatibility and accessories

This frequency converter is specifically designed for use with centrifugal pumps equipped with asynchronous motors. It is compatible with DN 1 1/4” male and DN 1 1/2” female pipe threads. For complete system integration, ensure that the pump’s control circuit includes the necessary wiring for pressure feedback and remote control inputs. Additional components such as pressure sensors or expansion modules may need to be ordered separately depending on the specific application requirements.

Technical background for designers

The ACTIVE DRIVER PLUS operates by modulating the frequency supplied to the motor, thereby controlling its rotational speed. This adjustment maintains a consistent pressure in the system even when the flow rate varies. The internal electronics include protections against dry-running, overcurrent, overheating, and abnormal voltage fluctuations. These safeguards help prolong the lifespan of both the pump and the drive unit. The housing is constructed to withstand normal environmental conditions encountered in mechanical rooms. Designers should consider the thermal management of the installation area to ensure proper ventilation and prevent overheating during extended operation.

Service and operation

Regular inspection of the device’s connections and cooling vents is recommended to prevent dust accumulation and overheating. Technicians should monitor the display for error messages and log any recurring faults for further analysis. In the event of a shutdown due to a fault condition, the cause must be identified and resolved before restarting the system. There are no scheduled maintenance intervals specified in the provided documentation. Always follow the manufacturer’s guidelines when servicing or replacing internal components.

Frequently asked questions

Can the ACTIVE DRIVER PLUS be used with three-phase motors?
Yes, the device is suitable for use with three-phase asynchronous motors commonly found in centrifugal pump applications.

Is it possible to adjust the setpoint pressure manually?
Yes, the user interface allows for manual pressure setting adjustments as well as viewing current operational parameters.

What happens if the pump runs dry?
The integrated dry-run protection triggers an alert and may shut down the pump to prevent damage to the motor and impeller.

Does the system support external control signals?
External control inputs are supported via the appropriate wiring configuration, allowing for integration with building management systems or pressure sensors.
