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.
•
Filling operation with 2 floats
Start
Pump P1
Float or level probe on B
Pump P2
Float or level probe on C
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.
Filling operation with 3 floats
Start
Pump P1
Float or level probe on B
Pump P2
Float or level probe on C
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 Ebox 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
•
as a 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.
The following table sums up the behaviour described:
