Grundfos LC 241 2 x 17-23 DOL 415v MO Outdoor Dual Pump Wastewater Pump Controller for Pit Emptying

Outdoor pit emptying applications require robust control solutions, and this controller is designed for such exposed environments. It coordinates dual pump operation by accepting signals from analogue level transmitters or float switches, ensuring pumps activate when wastewater levels require removal. The system provides automatic level control for residential, commercial, or industrial sites where consistent pit emptying is essential.

Operating specifications for the Grundfos LC 241 2 x 17-23 DOL 3X230/400 MO OPT support 415v three-phase pumps drawing 17-23 A per motor. Direct-on-Line starting is employed on 50/60 Hz mains frequency, with motor current monitoring supporting overload protection. The controller monitors motor current during operation to support overload protection in outdoor conditions.

Setup is simplified through Bluetooth commissioning using the Grundfos GO app, which provides a guided wizard for adjusting switching levels and protection parameters. Configurable inputs support analogue level transmitters, float switches and compatible level sensors for customized site configurations. Dry-running protection and alarm logging support unattended operation while BMS connectivity enables remote visibility.

An IP65 metal enclosure offers robust ingress protection for outdoor wall-mounted installations, resisting water and dust ingress. This RCM compliant controller operates reliably in ambient temperatures from -5°C to +40°C and includes a front-mounted interface for visual monitoring. Manual alarm resets and status confirmation are accessible during routine site inspections.
