Grundfos LC 232 User Manual

If the inflow of liquid exceeds the capacity of the installed pump, the
level in the tank or well starts to rise. Eventually, the High level
sensor registers a high liquid level in the tank or well. If set, the
signal from the High level sensor can be used to activate an output
relay which can then be used to give a visual or acoustic alarm or
send a signal to a SCADA system.
If the pump is running and the liquid level in the tank or well falls
below the dry-running level, the dry-running protection stops the
pump to ensure that it is not damaged mechanically.

5 Dry-running level
In the filling application, the pump is installed in a tank or well from
where it pumps the liquid. The liquid is pumped into a second tank
where the level sensors are installed.
The pump starts to fill the second tank when Start level P1 is
reached.
The pump stops when the liquid level reaches Stop level.
If the pump for some reason does not stop at Stop level and the
liquid level keeps rising, the High level sensor eventually
registers this. If set, the signal from the High level sensor can be
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 stops the pump to
ensure that it is not damaged.
