13.3 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
MAX
).
- DP represents the minimum level of the tank (L
MIN
).
If the level in tank reaches the SP value the pump P1 is started, and if the opportune starting threshold is
exceeded, within a time of 5 seconds, the pump P2 is also started.
Both pumps stop when the DP level is reached.
The following table sums up the behaviour described:
Sequence
Pump P1
Pump P2
START
Tank level > = SP
Pump P1= started for at least 5 seconds and with tank level
> = SP
STOP
Tank level <= DP
Tank level
<= DP + 2%
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.

DP= min. level = 25% = 1 m.
P1+P2 = ON
P1+P2 = OFF
SP= max level = 4 m
