Wilo-Control EC-L

Your advantages

  • Reliable control and monitoring of up to three pumps, thanks to various monitoring and alarm functions
  • Flexible level measurement with level sensor, dynamic pressure bell or float switches
  • Increased plant safety when controlling pumps in explosive areas by extending the monitoring functionality in Ex-mode (hardware and software)
  • Easy operation with alphanumeric, symbol-based menu and red-button technology
  • Operating statuses can be viewed at any time. Greater ease of use via integration with remote monitoring systems via Modbus or optionally via GSM
  • Flexible installation. Universal power supply for single-phase current and three-phase current and a wide operating temperature range of -30 °C to + 60 °C
  • Universal use for water supply and sewage disposal – also for pumps in potentially explosive atmospheres
  • Advanced system control with individual operation and fault signal, optionally also in the event of power failure
  • Additional operational safety thanks to separate level recording for high water and dry-running protection
Series description



  • Two different operating modes for a broad field of application:
    • "Drain" operating mode: For draining sewage chambers
    • "Fill" operating mode: For filling water tanks and rainwater storage tanks
  • Configurable overload protection
  • Thermal motor monitoring
  • Pump kick function
  • Adjustable follow-up time
  • Automatic pump alteration (for switchgear for 2 or 3 pumps)
  • Service life optimisation (for switchgear for 2 or 3 pumps)
  • Standby pump (for switchgear for 2 or 3 pumps)
  • Automatic fault-actuated switchover (for switchgear for 2 or 3 pumps)
  • Direction of rotation monitoring
  • High water alarm with forced switch-on of the connected pump(s)
  • Dry-running protection
  • Fault memory for 10 error messages including the type of fault
  • Operating mode "Ex" for loading presets for "Ex" applications


  • Display of the current operating status and data, as well as faults via the LCD display and LEDs
  • Symbol-based menu navigation
  • Configuration of operating parameters and operation via operating button
  • Main switch (depending on version)
  • Remote access via ModBus
  • Integrated alarm buzzer
  • Explosion-proof version for direct connection of sensors within potentially explosive atmospheres

Microcontroller-controlled switchgear for level-dependent control of two or three submersible pumps with analogue or digital signal transmitters. Individual parameters are entered via symbol-based menu navigation and an operating button.


  • 1x analogue precision input 4 – 20 mA for level control with level sensor to control 1 to 3 pumps
  • 2x (for 1 pump) or 3x (for 2 pumps) digital inputs for level control with float switch
  • 1x digital input for low water level with float switch (dry-running protection)
  • 1x digital input for high water signal with float switch (high water alarm)
  • 1x input for level control with an immersion bell (“IPS” version only)
  • 1x ... 3x inputs* for thermal winding monitoring with bimetallic temperature sensor. Connection of PTC sensors is not possible!
  • 1x ... 3x inputs* for connecting moisture sensors (e.g. motor compartment leakage or sealing chamber monitoring)
  • 1x digital input for External On/Off for remote activation and deactivation of automatic mode


  • 1x potential-free contact for the collective run signal (SBM)
  • 1x potential-free contact for the collective fault signal (SSM)
  • 1x potential-free contact for the individual run signal (EBM) per pump
  • 1x potential-free contact for the individual fault signal (ESM) per pump
  • 1x analogue output 0-10 V for the output of the actual level value

*Depending on the number of pumps that can be connected.
