User manual - COUNTER SLN-94
After initialisation if counting cycle (
point S, plot: a) all relay outputs are set to its
active
state.
During controlling cycle relays outputs can change its state to
inactive,
only
after
counter reach stored
threshold value
(
“Pr1”
for relay
R1
and
(“Pr1”
-
“Pr2”)
for relay
R2
;
points A, B, D, E in Figure 6.4a, Figure 6.5a )
.
Active
state of the relays (
on
or
off
) is defined by parameters
“mr1”
,
“mr2”
. The reaction of
the counter when it reaches
threshold value
is immediate. Parameters
“tr1”
and
“tr2”
defines how long the relay should stay
inactive
after the moment when counter reached the
threshold value
.
•
If parameter
“tr1”
or
“tr2”
is set to
“0”
then related relay stay
inactive,
until next
initialisation of counting cycle (manual: points C, F in Figure 6.4a, b, c or automatic: point
C in Figure 6.5a, b, c).
Description:
S
- initialisation of the counting cycle,
A, B
- points while counter exceeds selected value,
C
- automatic initialisation of counting cycle
