9. If a compressor is present, finish with its adjustment. The tank should be partly filled but the level should be below the ON
level. The setting is correct when an air bubble rises to the surface at regular intervals without the water level indicated on
the display changing. If the water level measured by the control box increases, the compressor is sending out too much air
and increasing the pressure in the pneumatic tube: the volume of air blown in must then be reduced by turning the regulator
dial in the other direction.
It is possible to test the control box without a pump:
1. Connect the control to a single-phase mains (connection of N and L1).
2. Set the motor current limits to 0.0 A.
3. Disable the phase error.
4. Bridge the control circuit TH2.
5. Deactivate the pump's thermal fault.
6. If the corresponding level sensors are connected, all program functions can be tested without connecting the pumps.
