Control EC-L
Series description
Your advantages
- Reliable control and monitoring of one or two 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 in potentially-explosive areas
- 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
Equipment/function
Functions
- Two different operating modes for a broad field of application:

Description/construction
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.
Inputs
- 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
Outputs
- 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.
