User manual - FLOW METER SPI-638
Total flow is displayed in units defined by parameter
“t unit”
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
total flow clearing 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
total flow clearing input
can be activated using „
E CLr
” option of
“totAL”
submenu (see page 38).
Batching counter value is displayed in units defined by parameter
“b unit”
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
batcher clearing 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
batcher
clearing input
can be activated using „
E CLr
” option of
“bAtCH”
submenu (see page 36).
Switching between current flow rate, total flow counter and batcher counter can be
done by pressing [
] button
. Kind of displayed value is signalised by
“
S
”
LED. It lights,
while total flow is displayed. If batcher counter is displayed then
“
S
”
LED is pulsing.
Batching counter can be displayed while batcher mode only (set „
SourCE
”=”
bAt
” in
„rELAy1”
submenu).
Functions of
[^]
and
[v]
buttons depend on kind of presently displayed value:
•
If instantaneous flow (flow rate) is displayed (LED marked
“
S
”
is off) or batcher counter
value (
“
S
”
LED is pulsing), user can check main threshold values and
number of batches
counter
(which indicates how many times batcher was started). After pressing
[^]
or
[v]
buttons, name of the threshold (e.g.
”rELPr1”
) and its value or
”bAtCnt”
label and
number of batches counter
will be displayed on the display in alternating mode.
If
[^]
or
[v]
will be pressed in 5 sec again, the next threshold will be displayed, else the
device comes back to the measurement mode. If a
free access
is enabled (see description
of
”SECu” menu
), user can change the value of particular threshold pressing button
[ENTER]
(see:
PARAMETERS EDITION
). Using
button while
number of batches
counter
is displayed and confirm
„CLEAr?”
message by
[ENTER]
button causes zeroing
number of batches counter
.
•
If particular parameter has been changed and confirmed in quick view mode, its
new value is displayed in alternating mode with parameter name by few seconds.
Confirmed changes may be checked or user can switch viewed parameter
pressing
[^]
or
[v]
button.
•
Number of batches
counter is incremented after each start of batching process
(every first start after batcher counter zeroing).
