7. Correct if necessary (voir 6.2.1 Parameter settings).
8. For three-phase pumps, check the direction of rotation of the pumps (refer to the installation/operating manual of the pump).
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 circuits TH2 and TH4.
5. Deactivate the pump's thermal faults TH1 (pump 1) and TH3 (pump 2).
If the corresponding level sensors are connected, all program functions can be tested without connecting the pumps.

The control box is equipped with an automatic key lock.
To set the lock settings, see 6.1.1 Keys > Managing the automatic key lock.

The water level evaluation and the high water level alarm remain active but the pump motor is not switched on if the
ON level or the alarm level is reached.
The pump is switched according to the level measured by the selected sensor (see 6.2.1 Parameter settings). All
monitoring and safety functions are operated according to the saved settings.
