The product operates normally.
8.3.3 Leakage detection
If the on/off valve is closed but the product detects that the fluid still flows, then the product generates an
out-of-specification event.
The function is active by default.
To make sure that the function is active, do the following procedure:
Connect the product to the Bürkert Communicator software. Refer to Connect the product to the Bürk-

In the Bürkert Communicator software, select the product.
Go to Controller > Parameter > Use unexpected flow detection
Choose Yes
The leakage detection is active.
8.3.4 Detect the end of dosings
The product is able to detect automatically when the mass flow rate is equal to zero after the valve is
closed. The detection time is called balancing time.
As an alternative to the automatic detection, you can set a fixed balancing time after which the product
considers that the dosing is finished.
The dosed quantity is transmitted at the end of the balancing time.
To activate the automatic detection of a null flow rate, do the following procedure:
Connect the product to the Bürkert Communicator software. Refer to Connect the product to the Bürk-
ert Communicator software [
}
37]
In the Bürkert Communicator software, select the product.
Go to Controller > Parameter > Use balancing time autom. detection
Choose Yes
The product automatically detects when the flow rate is null.
If the product detects a non-null flow rate after the maximum balancing time has elapsed, then the
product generates an error event.
To set a fixed balancing time, do the following procedure:
Connect the product to the Bürkert Communicator software. Refer to Connect the product to the Bürk-
ert Communicator software [

Balancing time
Enter a duration.
The product waits the end of the balancing time to consider that the dosing is finished.
If the product detects a non-null flow rate after the set balancing time has elapsed, then the product
generates an error event.
