Grundfos LC 241 2 x 4-6,3 DOL 415v MI Indoor Dual Pump Wastewater Pump Controller for Stormwater

Developed for stormwater management, this indoor controller provides dual pump automation for efficient water level control in collection systems. It accepts signals from analogue level transmitters or float switches to initiate pump operation when predetermined levels are reached. The system supports automatic pump sequencing and alternation for consistent service duty in commercial installations.

Electrical specifications for the Grundfos LC 241 2 x 4-6,3 DOL 3X230/400 MI OPT support 415v three-phase pumps with a 4-6.3 A current rating per motor. Direct-on-Line starting logic operates on 50/60 Hz mains frequency, with individual motor current monitoring supporting overload protection. The controller monitors motor current during operation to maintain reliable service.

Bluetooth commissioning via the Grundfos GO app enables wireless configuration of start and stop levels without cabinet access. Configurable inputs support analogue level transmitters, float switches and additional sensors for customized site requirements, while integrated logic provides dry-running protection and BMS connectivity. Alarm logging supports remote troubleshooting and system performance tracking.

A painted metal cabinet with IP54 enclosure protects internal components in wall-mounted indoor installations. This RCM compliant controller operates in ambient temperatures from -5°C to +40°C and includes a front control panel for status visibility. The assembly provides manual reset capability and immediate access to system warning logs.
