User manual for - FLOW METER SPP-N118
“bAt”
option is available for relay
R1
only. For the rest of relays „
PrE r1
” option is
available. „
PrE r1
” option means controlling in relation to „
SEt P
” of relay
R1
(see
CONTROL OF THE RELAY OUTPUTS
).
“SEt P”
- first threshold of the relay (range 0 ÷ 999999).
Threshold is the medium value of
relay hysteresis.
While batcher mode (
„SourCE”=„bAt”
)
„SEt P
” value means the
quantity of pouring matter.
“SEt P2”
- second threshold of the relay (range 0 ÷ 999999). This threshold is accessible
when
”modE”
parameter is set to
„in”
or
„out”
value.
Threshold is the medium
value of relay hysteresis.
“HYSt”
- hysteresis of relay (range 0 ÷ 99999). Full hysteresis of the relay is equal to 2x
“HYSt”
parameter. The relay state can change when an input signal is out of
threshold-hysteresis
to
thhysteresis
zone.
Presented parameters should be set to ensure that
”SEt P” + ”HYSt”,
”SEt P2” + ”HYSt”, ”SEt P” - ”HYSt”
or
”SEt P2” - ”HYSt”
do not exceeds the
measure range. Additionally, in two threshold mode (“
modE
”= „
in
” or „
out
”), the
hysteresis for both thresholds must not cover each other (in other case relay can't
change its state).
“b PrEc”
- decimal point position (displaying precision of the relay thresholds ) when relay is
controlled due to batcher counter result. It can be set to:
“ 0“
“ 0.0“
“ 0.00“
“0.000“
Decimal point position is changed by
[^]
,
[v]
buttons.
“b unit”
- the unit of relay thresholds when relay is controlled due to batcher counter result. It
can be set to:
“lit.”
- Litres
“m 3”
- cubic meters
Parameters ”
b PrEc
” and ”
b unit
” are available only for relay
R1
while batcher
mode (
“SourCE”
=
”
bAt
”) is set. When current flow rate is used to control relays,
the unit and precision of the thresholds and hysteresis are defined by parameters
“F unit”
,
“Ftunit”
and
“F PrEc”
of menu
”Flouu”
. When relay (other than
R1
) is
controlled in relation to „
SEt P
” threshold of relay
R1
(
“SourCE”
=
”
PrE r1
”), the
unit and precision of the thresholds and hysteresis of relay (other than
R1
) are
defined by parameters
„b unit”
and
„b PrEC”
parameters available in submenu
of relay
R1
.
“t PrEc”
- decimal point position (displaying precision of the relay thresholds ) when relay is
controlled due to total flow counter result. It can be set to:
“ 0“
“ 0.0“
“ 0.00“
“0.000“
