Controller EC 531 is an all-in-one unit for intelligent control and monitoring of sewage pumping stations with one or two pumps.

The equipment controller ensures increased efficiency and reliability of municipal pumping stations and supports all aspects of the LCC (life cycle costs) calculations.
EC 531 offers straightforward control and monitoring via floats or advanced control via a continuous level signal. EC 531 is also equipped with smart VFD control including PID and BEP, which save energy, and equipment costs.
The new equipment controller EC 531 gives instant access to alarms, pump status, level information and trends. It offers functionalities to help monitor the equipment condition as well as to optimize and reduce the risk of overflow, cut down energy costs, etc.

Key control parameters of the EC 531 are:

  • Level set-point, including time delays
  • Speed of level change
  • Random start levels
  • Tariff control
  • Maximum runtime
  • VFD control logic, including flow calculation, day set points, night set-points and adjustable pump reversal speed
