Grundfos - LC 241 1x 8-12 SST Level Controller - 400V - Three Phase - For 1 Pump - 99877211
LC 241
The LC 241 level controllers offer a comprehensive range of incorporates for control and monitoring of pumps in waste water and drainage systems or tank filling in water supply. The LC241 is a metal or plastic cabinet solution offering modularity and customization in compliance with your needs.
The LC 241 pump controllers are designed for level control, monitoring and protection of Grundfos fluid conveyance systems one pumps or two pumps starting direct-on-line, star delta or as soft starter. The LC 241 pump controllers is applicable in various type of empty application e.g. waste water transport, drainage or tank filling in water supply.
The set-up of the control is easily done either by the predefined application settings or via the step-by-step start-up wizard in the intuitive Grundfos GO app, using Bluetooth Smart technology. With the Grundfos GO app, all detailed pump settings can be easily being configured, monitored and fully commissioned and tested.
The controller is furnished with configurable input/output terminals, giving full flexibility for all applications. However, as option the IO 241 module with more input/output options can be build-in. Additional options like manual ON/OFF/AUTO switch, current transformer, Ex barrier for digital and analog pressure sensor input, system fault condition light, can also be part of your customized solution.
Daily control, supervision and commissioning is straightforward with the intuitive and easy- to-use user interface. This saves you valuable elapsed operating time when getting started, and in your daily interaction with pumps and the controller. The controller integrates seamlessly into the Grundfos range of communication modules, ensuring an easy fit into any supervisory system such as SCADA or Grundfos CLOUD.
The controller maintains a detailed alarm and warning log with the last 20 alerts. The system fault condition event log can be accessed remotely via SCADA or Grundfos CLOUD. You can also use Grundfos GO to inspect the logs in localized, translated text for easy troubleshooting and remedial measures at the fluid conveyance station.
The LC 241 controller enable:
- Control of 1 or 2 pumps based on signals from pressure sensor input (analog, 0-5 V, 0.5-3.5V, 0-10 V, 0-20 mA, 4-20 mA or digital, float switch)
- Support up to five control levels for both analogue level transmitter or float switch operation
- Supports simple application where only one float switch is present - single float switch operation
- Configurable input/output terminals that is applicable as digital input/output, analogue input and Pt 100/1000 inputs for flexible use in the actual application.
- Prevent the pumps with anti-seizing from choking or seizing due to limestone build-up or other deposits
- Prevent the mains system load when several fluid conveyance stations are started up at the same elapsed operating time with power-on delay.
- Protection against hydraulic shock (water hammer) as quick restart/simultaneous start is blocked and delayed
- Selection of automatic alarm resetting
- Setting of stop delays matching the actual operating conditions
- Shows the actual liquid level
- Alarm indication via build in buzzer

Alarm indication of:
- Power/current measurement (Optional)
- Dry running
- High water level
- Incorrect phase sequences or missing phase
- Pressure sensor inconsistency or failure
- Intrusion detection
- Water on floor
- Too many restarts
- Pump overheating and moisture detection
