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
