3.6 Testing the product
When you have made all the electrical installations and completed the startup wizard, you can test the system.
For emptying applications:
• Fill the pit with water and check that the pump starts automatically at the defined level.
• 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.
• Test the high-level function by stopping the pump manually and continue to fill the pit with water. Check that the control unit indicates an
alarm when the defined level is reached. Set the pump to Auto and observe that the pump starts and stops when the stop level has been
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.
