The level-control unit is designed to control one or two pumps. The product can be configured for two purposes: dewatering in groundwater supply or filling a tank.
The control unit switches the pump on and off according to the liquid level measured by level switches or a pressure sensor.

Level control:
• When the start level is reached, the pump starts, and when the liquid level is lowered to the stop level, the LC control unit stops the pump.

Pressure control:
• When the start pressure is reached, the pump starts, and when the liquid level is lowered to the stop level, the LC control unit stops the pump..
An alarm is indicated in case of, for example, high water level in the tank or sensor failure. The control unit is available in two variants:
• LC 232 provides a compact solution with integrated motor protection.
• LC 242 is a cabinet solution that allows setup customisation.
