User manual for - FLOW METER SPP-N118
Total flow is displayed in units defined by parameter
“t unit”
(L or m
3
), with resolution
defined by parameter
“t PrEc”
(max 3 digits after decimal point). If total flow counter
overflows, warning
“tot ov”
is displayed alternatively with maximum counter value. Total flow
counter can be zeroed using
“Clrtot”
option of
“totAL”
submenu, using
button (press
and hold by at least 2 sec.), electrically via
programmable input
or via RS-485 interface by
writing of value 0000h to any of total flow counter result registers.
Zeroing by
button can be activated using „
m CLr
” option of
“totAL”
submenu.
Zeroing via
programmable input
can be activated using „
Func
” option of
“Pr inP”
submenu.
Parameter
“CutoFF”
, allows to define input current value, below which total amount of
flow
is not counted
(incremented).
If “CutoFF” is set to value different than zero and if input current is lower than
this value, then instantaneous flow (flow rate) is displayed, but TOTAL
COUNTER IS NOT INCREMENTED.
Cutoff Threshold “CT” is defined by formulas below:
CT
=
" CutoFF"

Batching counter value is displayed in units defined by parameter
“b unit”
(L or m
3
), with
resolution defined by parameter
“b PrEc”
(max 3 digits after decimal point). If batcher counter
overflows, warning
“bAt ov”
is displayed alternatively with maximum counter value. Batching
counter can be zeroed using
“CLrbAt”
option of
“bAtCH”
submenu, using
button (press
and hold by at least 2 sec.), electrically via
programmable input
or via RS-485 interface by
writing of value 0000h to any of batcher counter result registers.
Zeroing by
button can be activated using „
m CLr
” option of
“bAtCH”
submenu.
Zeroing via
programmable input
can be activated using „
Funct
” option of
“Pr inP”
submenu.
Switching between current flow rate, total flow counter and batcher counter can be
done by pressing [
] button
. Kind of displayed value is signalised by
“
Σ
”
LED. It lights,
while total flow is displayed. If batcher counter is displayed then
“
Σ
”
LED is pulsing.
Batching counter can be displayed while batcher mode only (set „
SourCE
”=”
bAt
” in
„rELAy1”
submenu).
