Set-up parameters meaning:
LF
Functioning level
- Allows to change the functioning mode:
1 single level computing head
2 cascade 2 levels computing head
3 cascade 3 levels computing head
St
Functionality Electro valve1
- Allows to change the intervention mode of the
EV1:
0 Electro valve active only during phase 1
1 Electro valve active during the whole
refuelling process
2 Equal to 0 but with EVs closed
3 Equal to 1 but with EVs closed
Mt
Meter type
- Allows to inform the CPU about the type of used
flow meter:
0 Impulsive type
1 Modbus Krohne type
2 Modbus MicroMotion type
3 Modbus Hauser

L0
Low flow rate 1
st
...2
nd
level
- Represents the delivering value in dag/s, under
this value the computing head switch on the next
level (or stop the delivery if mono-level)
t0
Acquisition delay L0
- Represents the time between the acquisition of the
L0 status and the start of the next level (or
refuelling ending procedure if mono-level)
L1
Low flow rate 2
nd
…3
rd
level
- Represents the delivering value in dag/s, below
than that the computing head switch on the next
level (or stop the delivery if bi-level)
t1
Acquisition delay L1
- Represents the time between the acquisition of the
L1 and the start of the next level (or refuelling
ending procedure if bi-level)
L2
Low flow rate for 3
rd
level
- Represents the delivering value in dag/s, below
than that the computing head considers to be in
minimum delivering condition at the end of 3
rd
level, and stop the delivery
t2
Acquisition delay L2
- Represents the time that must elapse between the
acquisition of the status of L2 and the start of the
ending delivery procedure.
