3.6 Testing the product
When you have made all the electrical installations and completed
the startup wizard, you can test the system.
For dewatering applications:
•
Ensure the pit is filled with water and check that the pump starts
automatically at the defined level.
•
If possible, test the dry-running function by starting the pump
manually and wait while the pit with the pump is emptied. Check
that the control unit indicates an alarm and stops the pump
when the defined level is reached.
For filling applications:
•
Start by draining the tank to be filled. When the tank is empty
and the start level is reached, the pump must start. When the
tank is full and the stop level is reached, the pump must stop.
•
Test the high-level function by stopping the pump manually and
continue to fill the tank without the pump with water. Check that
the control unit indicates an alarm when the defined level is
reached.
•
Test the dry-running function by starting the pump manually and
wait while the tank with the pump is emptied. Check that the
control unit indicates an alarm and stops the pump when the
defined level is reached. If the pump is placed in a well, this test
may not be possible since the pump cannot empty the well.
Alternatively, pull the dry-run level switch up to simulate a dry-
run situation. The same can be done with a pressure level
sensor.
4. Product introduction
4.1 Product description
The level-control unit switches the pump on and off according to the
liquid level measured by float switches or a pressure sensor. When
the start level is reached, the pump starts, and when the liquid level
has been lowered to the stop level, the pump is stopped by the
control unit. An alarm is indicated in case of for example high-water
level in the tank or sensor failure.
Basic settings are configured via the operating panel and advanced
settings are configured with Grundfos GO Remote. Furthermore,
you can read important operating parameters with Grundfos GO
Remote.

The pump starts to empty the tank or well when Start level P1 is
reached.
A second pump starts when the liquid level reaches Start level P2.
The pump stops when the liquid level is lowered to Stop level.
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
