System operation:

Operation with 2 floats or level probes

The operating logic is the following:
Float or level probe connected to input B starts pump P1 and stops both pumps.
•
Float or level probe connected to input C starts pump 2.
•

Operation with 3 floats or level probes

The operating logic is the following:
Float or level probe connected to input B starts pump P1.
•
Float or level probe connected to input C starts pump P2.
•
Both pumps are stopped on the float or level probe connected to A.
•
Note: the function with 3 floats is used in installations with deep narrow tanks that do not allow an ample travel of the
floats!

Operation with depth sensor and display

If a depth sensor is being used, with an E.box with display, it will be possible to set independently the starting level of pump P1, of pump P2, and
the stopping level of both. In particular:
HA is the stopping level of the pumps P1 and P2.
•
HB is the starting level of pump P1.
•
HC is the starting level of pump P2.
•
It will also be possible to set the alarm level for maximum or minimum tank level. The minimum settable level (including the minimum alarm level)
cannot be lower than 15 cm. The maximum settable level (including the maximum alarm level) cannot be higher than the tank height minus 5 cm.
The various levels are separated from one another by a minimum of 5 cm.

Operation with depth sensor without display

In operation with a depth sensor, the parameters must be set with the Trimmers SP and DP:
SP represents the maximum level in the tank (L
•
DP represents the minimum level in the tank (L
•
percentage of SP.
If the level in the tank is the same as or lower than DP, the pump P1 is started and, if the level continues to fall, pump P2 is also started after a
delay of 4 seconds.
When level SP is reached, both pumps stop.
