Terminals; Identification - Grundfos LC 241 Montage- Und Betriebsanleitung

used to activate a relay output which can then be used to give a
visual or acoustic alarm or send a signal to a SCADA system via a
communication interface.
If the pump is running and the liquid level in the tank falls below the
dry-running level, the dry-running protection will stop the pump to
ensure that it is not damaged.
