Pump controller for filling and emptying applications
The LC 231 pump controller is designed for level control, monitoring and protection of Grundfos single or duplex pumping systems.
Features and benefits include:
- Control of 1 or 2 pumps based on signals from 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 can be used 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 load when several pumping stations are started up at the same time with power-on delay
- Protection against 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 a built-in buzzer
We’re Experts on Pump Controls
A drive can help lower energy consumption at wastewater pumping stations, but a drive on its own is not enough. For an optimized system you also need an intelligent and complete wastewater control and monitoring solution.
The Grundfos CU 362 (Dedicated Controls), was developed specifically for network pumping stations and allows for system measurement and calculation, and integration with other monitoring, control, and energy optimizing equipment.
