Intelligent pump control with Wilo-EC-L-2x12A-DOL-MT34-WM

This advanced control unit, designed for reliable control of two submersible pumps, offers a wide range of functions and configuration options. The microcontroller solution allows for flexible adaptation to various applications, from draining sewage sumps to filling tanks. The device combines intuitive operation with advanced monitoring and protection functions.

Functionality and application

Wilo-EC-L-2x12A-DOL-MT34-WM is a versatile device, ideal for pumping systems requiring precise liquid level control. The ability to operate in "Drain" or "Fill" mode makes it suitable for various installations. The intuitive LCD display with a symbolic menu simplifies configuration and monitoring of operating parameters. Additionally, the Modbus interface enables remote access to data and device control.

The device is equipped with a number of protections, such as overload protection, motor thermal control, and dry-running pump prevention function. The built-in high-level alarm with forced pump activation provides additional installation safety. The ability to automatically switch pumps optimizes their operating time and increases system reliability.

Construction and parameters

The housing made of durable polycarbonate (PC) provides high resistance to mechanical damage and external factors, and the IP54 protection class guarantees safe use even in harsh environmental conditions. The device is adapted to cooperate with various types of level sensors – analog (4-20 mA) and digital (float switches). The device's power supply can be implemented in the voltage range of 220…400 V at a frequency of 50/60 Hz. The maximum rated current for each pump is 12 A, allowing control of most standard submersible pumps. Compact dimensions (310 x 230 x 155 mm) facilitate installation in limited space. The weight of the device is approximately 2 kg, which facilitates its transport and installation.
