Control device Wilo-EC-L-2x12A-DOL-MT34-WM-EMS-IPS 2543222

Intelligent pump control – reliability and efficiency with Wilo-EC-L

The Wilo-EC-L-2x12A-DOL-MT34-WM-EMS-IPS control unit is an advanced system designed to control the operation of two submersible pumps. This microcontroller-based device, designed for precision and reliability, optimizes system performance, reduces operating costs, and increases user comfort. Thanks to the ability to control via both analog and digital sensors, the device works perfectly in various applications.

Functionality and application

This device is a versatile solution for installers and users looking for an intelligent way to manage pumping systems. It is primarily intended for controlling pumps in sewage wells and water tanks and cisterns. The ability to choose the operating mode – draining or filling – provides flexibility and adaptation to specific installation needs. Built-in protections, such as motor thermal control and overload protection, guarantee safe and long-lasting system operation.

The device offers a number of functions to facilitate diagnostics and maintenance:

• Automatic failover switching between pumps ensures continuity of operation in the event of a failure of one of them.
• Memory for 10 failure messages with information about the type of fault facilitates quick problem identification.
• LCD display and LEDs inform about the current operating status of the device and any errors.
• Remote access via the ModBus interface allows integration with building monitoring and management systems.

Construction and parameters

The device is characterized by a solid construction and a high degree of protection IP54, which ensures its resistance to harsh environmental conditions. The polycarbonate housing is UV resistant, guaranteeing durability even when exposed to sunlight. A wide range of supply voltage (220…400 V) and frequency (50/60 Hz) makes the device compatible with various electrical installations. The maximum rated current for each pump is 12A, allowing control of pumps with a power of up to 4 kW. Direct-on-line starting (DOL) simplifies system installation and configuration.
