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 level sensors are installed.
The pump will start to fill the second tank when Start level P1 is
reached.
A second pump will start if the liquid level reaches Start level P2.
The pump stops when the liquid level reaches Stop level.
If, for any reason, the pump does not stop at Stop level and the
liquid level keeps rising, the High level sensor will eventually
register this. If set, the signal from the High level sensor can be
used to activate a relay output which can then be used to activate 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
avoid any damage.
