User manual - COUNTER SLIK-94
Maximum delay between the moment when result reaches the particular threshold and
switching on the relay output equals 15ms for OC type output and 20ms for electromechanical
relays.
If
AUTORESET
function is active, and counter changes its value with high speed,
relays other than R1 (if available) can not change it's states to active , because the
time between moments when counter reaches their thresholds and threshold value
of relay R1 (greater than for other relays thresholds ) is to short.
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.
Parameter “timE” defines how long relay stay active after its activation by counter value (after
moment when counter has reached particular threshold).
• If parameter
“timE”
is set to
“0”,
than relay stays in
active
state (periods: t
A
,t
C
,t
E
,t
G
) as
long as counter value is equal or higher than threshold value. (traces: b, c).
• If parameter
“timE”
is set to value different from
“0”
, than relay stay active during defined
time regardless of counter value (traces: d, e). In case when period (t
X
) between
successive exceeding of threshold value (e.g. between points B and C) is shorter than
period defined by parameter
“timE” , activation period of relay is prolonged by “timE”
(every time when counter value goes up and reaches threshold).
If parameter “timE1” = “0” and AUTORESET function is active, relay R1 will not
change it's state to active or will be activated on very short time because of delays. If
user wants to not use particular relay (especially relay R1), its mode of operation
should be set to ”
noAct ” (e.g. „ mode 1 ” =” noAct ”).
Parameter
“modE”
can be set to value “modbuS”. In such case it is possible to drive
relays via RS-485 interface. In this case relays are independent on counter value, and „
time
”
and „
SEtP
” settings, and change of it's state can be done exclusively via RS-485 interface, as
presets of holding registers (see: LIST OF REGISTERS ) . While parameter “modE” is set to
value
”on”
or
”oFF”
, presets of these registers do not causes any reaction, and reading of
these registers show actual state of particular relays.
If “modbuS” mode is active, than after power down and up relays are inactive.
All parameters corresponding to relay outputs are described in details in chapter
”rELAy” menu .
