User manual - COUNTER SLIK-94
Counter recalculates result using three parameters -
mul
,
div
and
offset,
and shows it on the
display. If the result is out of
permissible counter range
(from“-99999” to “999999”), special
warning is displayed in place of the result. The warning type depends on the result and can be:
–
“-Hi-”
- if the result is higher than “999999”,
–
“-Lo-”
-if the result is lower than“-99999”,
Any time the counter can be zeroed at by:
–
pressing of the
[RESET]
push-button and the confirmation of the
[ENTER]
button,
–
activating the external reset input (see:
“rESEt” menu
),
–
presets of the internal registers via RS-485 interface.
After zeroing, the result equal to the “
oFFSEt“
parameter is displayed. (see:
“PrESCA”
menu
).
In the measurement mode user can check main thresholds values. After pressing
[^]
button, name of the threshold (e.g.
”rELPr1”
) and it's value will be displayed on the display in
alternating mode. When the batcher mode is active, additionally the
”oFFSEt”
parameter can
be checked. If
[^]
or
[v]
will be pressed in 5 sec again, the next threshold or offset will be
displayed, else the device comes back to the measurement mode. If a thresholds values
free access
is enabled or thresholds and offset values
free access
is enabled (see:
”SECu”
menu
), user can change the value of particular parameter pressing button
[ENTER]
(see:
PARAMETERS EDITION
).
All accessible parameters can be changed by entering the menu (see:
DEVICE
PROGRAMMING
). Use the local keyboard or the remote controller to do it. (Note: all
parameters can be remote changed via RS-485 interface).
•
Counting and relays controlling are independent of operation mode of the
counter. They are continued (in background) even in menu mode, but in such
case maximal input frequency should be not greater than 8 kHz.
•
If
”PArUPd”
option is set to
”on rES”
mode, then change of parameters
”muL”
,
”div”
,
”oFFSEt”, ”Point”
and all parameters of the relays controlling
(see
”rELAy”
menu), has no influence on current counting process. In this
mode changed parameters will be applied after reset (manual or automatic) or
next device power up. If
”PArUPd”
option is set to
”immEd”
mode, then all
changes of these parameters are applied immediately.
6.2.
BATCHER FUNCTION
as a batcher, proper connection to controlled circuit must be
done (e.g. valves and flow detector) and parameter
“A oFFS”
must be set to
“on”
option (see
description of
”SECu” menu
). In example showed on page 17 producer assumes
use of two
valves: main (biger) and additional (smaller).
To use the counter as a batcher (it means to counter displays how much of some fluid should
be poured to fill tank) parameter
”Funct”
should be set to option allowed subtraction of pulses
delivered to counting inputs. If programmable input
{ C }
is used to change direction of
counting (see description of
”Pr inP” parameter
), state of this input must be taken into
consideration.
