Leo OMNIA 2D T 400V - Electronic Control Panel for 2 Three-Phase Pumps 0.75-10 HP

The Leo Omnia 2D T 400V is an electronic control panel for two three-phase pumps with direct start, designed for wastewater and clear water lifting and for pressurization. It operates with a 400 V three-phase power supply, covering power ratings from 0.55 to 7.5 kW (0.75-10 HP) and automatically learning motor data.

A single control panel for electric pumps replaces multiple dedicated solutions: it manages float switches, pressure switches, and probes. The compact box is easy to install. The motor protection system and alternation functions make the control panel suitable for civil, industrial, and agricultural systems.

Functional Specifications

2-Pump Alternation and Peak Management

The control panel automatically manages the alternation between the two pumps and their simultaneous operation during peak times, optimizing motor wear and system performance. It is also programmable for both pressurization and lifting applications, with configurable start and stop delays to suit specific installation needs.

Intelligent Motor Protections and Electrical Safety

The control panel performs automatic motor data learning, calibrating protection thresholds automatically without manual settings. Included are overcurrent and undercurrent protections with a dedicated alarm, protection against voltage surges, phase sequence error control, and dry-running protection by reading minimum amperage and cosphi. There is also protection against motor klixon trips, with a specific thermal sensor for submersible pumps.

Advanced Functions and Connectivity

In addition to automatic motor data learning, the control panel features an automatic motor test function and programmed maintenance, useful for reducing unexpected system downtime. BMS readiness allows for remote connection for system monitoring, while the advanced Multitank program enables independent management of two pumps installed in two separate tanks.

Inputs and Operating Modes

The control panel accepts commands via float switches, pressure switches, or level probes, with a dedicated input for probe level control and four inputs for float switches, plus two inputs for motor thermal sensors. The green light indicates automatic pump operation, while the blue light indicates mains power; the STOP and reset button allows for immediate manual intervention in case of operational necessity.
