User manual - COUNTER SLIK-638
Zeroing of the counter can be done via RS-485 interface (by presets of some
registers with value 0000h) independently of the
„rESEt”
parameter value. After
zeroing the counter, displayed value is equal to „
oFFSEt”
parameter. Remote
zeroing is available in all modes (
”ALL”
,
“EL”
,
“mAn”
,
„nonE”
).
7.3.5.
“ArESEt” parameter
This parameter enables the auto zeroing mode (
AUTORESET
function). If
AUTORESET
is active the counter is zeroed instantaneously after result reaches the relay R1 threshold
value (
SEtP 1
) or after result reaches value lower than 0. This parameter can be set to:
“oFF”
-
AUTORESET
function is inactive.
“on Pr1”
- counter is zeroed after result reaches relay R1
threshold.
After zeroing,
counter value is equal to
“oFFSEt”
value
“on 0”
-
counter is zeroed after result reaches value lower than 0
.
After zeroing,
counter value is equal to (
SEtP 1
+
“oFFSEt”
- 1)
value
While
AUTORESET
function is active some conditions must be fulfilled:
–
If
“ArESEt”=“on Pr1”
then
„
oFFSEt
” <
”SEtP 1”
–
If
“ArESEt”=“on 0”
then
„
oFFSEt
” +
”SEtP 1”
> 0
If these conditions will not be fulfilled then counter can work improperly or can't work
at all.
7.3.6.
“FiLtEr” parameter
This parameter enables the digital filter, which filters the contacts oscillations of switches
(mechanical detectors). Digital filter eliminates the counting errors when mechanical detectors
are used. This parameter can be set to values:
”OFF”
,
”10”
÷
”90”,
where its value express
the maximum passed frequency, if
”OFF”
is set the filter is disabled (see
DIGITAL FILTER
,
page 20).
7.3.7.
“PArUPd” parameter
This option allows to define when such parameters as
”muL”
,
”div”
,
”oFFSEt”
,
”Point”
and all relay control parameters will be updated if some changes are applied in device menu.
Possible values:
”immed”
- changed parameters are updated immediately,
”on rES”
- changed parameters will be updated after next reset
(manual or automatic) or after
next device power up.
