User manual - COUNTER SLB-94
modE1
÷
modE4
- relay operation mode, this parameters define the active state of the
relay, it means state of relay while the counter reaches
threshold
value
, at up counting , available modes:
“noAct”
- the relay is not active (permanent turned off)
“on”
-
the relay is turned on (closed) when result reaches
threshold
value
“oFF”
-
the relay is turned off (opened) when result reaches
threshold
value
“modbuS”
-
the relay is controlled via RS-485 interface, independently on the counter
result and parameters
SEtP
and
timE
.
When a particular LED lights, its mean the relay is closed,
If parameter
“
modE
”
is set to
modbuS
value, after power supply off and on
again, relays are open.
timE1
÷
timE4
-
the time period of the relay
active state
. Can be set to values from
0.1 to 99.9 , and express the time in seconds or minutes
(depending on
unit
parameter).
If this parameter is set to value
different from 0.0 the relay is
active
independently of the result
(even if the counter is zeroed). If this parameter is set to 0.0 the
relay stays
active
as long as the result is same or higher of the
particular
threshold value
.
While parameter
timE 1
=
0
and
AUTORESET
is active, relay R1 will not
change its state to
active,
or due to delays will be activated for very short period of
time. If user wants not use R1 it is recommended to set
modE 1
=
noAct
.
unit 1
÷
unit 4
-
unit of time for
timE
parameter. Can be set on one of two values:
“min”
- minutes,
“SEC”
- seconds.
7.3.2.
“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 19).
7.3.3.
“CyCLE” menu
This menu contains settings of
cycles counter
.
modE
- this parameter describes
cycles counter operation mode
while
cycles counter
works in standard mode.
”rELAy1”
- cycles counter counts the number of of R1 relay switchings.
”ArESEt”
- cycles counter counts the number of main counter autoresets. If
AUTORESET
function is disabled then cycles counter will not be incremented.
