s.r.l.
tF
duration of the first puff
- To measure the CNG pressure at the beginning of
the delivery, it is necessary to fill the gas pipeline.
tF
is the time assigned to this activity.
(
the parameter is visible only when AC=1
)
tS
duration of the second puff
- To calculate the quantity to be delivered it is
necessary to measure the bottle pressure after its
partial filling up.
tS
is the time assigned to this
second activity.
(
the parameter is visible only when AC=1
)
dr
awaiting reading
- Before reading the pressure values it is necessary
waiting that variations damp.
dr
is the time
assigned to this activity.
(
the parameter is visible only when AC=1
)
Po
POS Option
- The computing head changes the amount sent in
the following way:
0 amount X 1 (not scaled value)
1 amount X 10 (one digit left scaled value)
2 amount / 10 (one digit right scaled value)
Pr
Kind of preset
- Depending on this parameter, the computing head
can deliver (see also
P1
and
P2
parameters):
0 no preset
1 preset in Kg or Smc
2 preset in currency
bP
Low flow
- It shows how many dag the optional solenoid valve
for high flow switches off before reaching the
preset value.
cA
Advance end of delivery
- It shows how many dag the solenoid valve for
delivery switches off before reaching the preset
value (Automatically calculated); in particular:
0 pre-stop disable
1 pre.stop calculation enable with -5dag
2 pre.stop calculation enable with -4dag
3 pre.stop calculation enable with -3dag
4 pre.stop calculation enable with -2dag
5 pre.stop calculation enable with -1dag
6 pre.stop calculation enable with 0dag
7 pre.stop calculation enable with +1dag
8 pre.stop calculation enable with +2dag
9 pre.stop calculation enable with +3dag
10 pre.stop calculation enable with +4dag
11 pre.stop calculation enable with +5dag
