3. Start-up of the Control System
3. Start-up of the Control System
After the system is connected to the power supply, a short system test is run, during which time the LED
light is red. The LED then becomes green when the start-up phase is completed.
During the system test, the notification "SYSTEM TEST ... OK", the program version, and serial number of
the control system appear for a short time. Following this, the current operating status of the system is
displayed. After the system test is complete, the date and the current time should be checked and adjust-
ed if necessary (see Section 4.2.3).
After checking the date/time, a functional check of the system components must be carried out. This
check can only be carried out if the necessary air hoses are connected. The check should be carried out
via the menu point "manual mode" in the control system, which is intended for this purpose. The individual
parts of the system are tested for functionality.
After a successful check, the system is reset to automatic mode.
In two-tank systems, the additional air distributor mounted on the control unit (see Fig. 1) should be set
according to the installation situation. To do this, select "Manual operation" on the control unit (see section
4.2.2 ) and switch on aeration. While aeration is switched on, the valves must be set so that sufficient
sludge is fed back and bubble formation is even in both tanks.

CAUTION: The clear water siphon only functions when the containers are filled.
If the date and time are not set correctly, operating faults will be stored with the incorrect time information.
