Operation With Sensor - DAB E-BOX 2G M Mode D'emploi

N.B. Instead of the floats, electric probes may be connected.
ONLY WITH CLEAN CLEAR WATER!
Operation with 3 floats is used in installations with deep narrow tanks that do not
allow an ample excursion of the floats!

12.3 Operation with sensor

In operation with a sensor the parameters must be set with the Trimmers SP and DP:
- SP represents the maximum level of the tank (L
- DP represents the minimum level of the tank (L
If the tank level is equal to or less than DP the pump P1 starts and if the level continues to fall the pump P2 is
also activated.
Both pumps stop when the SP level is reached.
The following table sums up the behaviour described:
Sequence
START
STOP
Both with float operation and with sensor operation there will be an
automatic exchange of the order of switching on the two pumps at each start,
or an exchange between the two pumps every 24 hours, depending on the regulation
chosen in the DS_A2.
The two pumps will always be started alternately with a minimum interval of
2 seconds between one and the other.
