User manual - COUNTER SLN-94
Description:
S - initialisation of the counting cycle,
A, B, D - points while counter exceeds selected value,
C - automatic initialisation of counting cycle
Figure 6.6 Example of relay outputs driving
during downcounting (parameter ” Ar ”=” on ”)
6.5. CONTROL OF THE RELAY OUTPUTS (STANDARD MODE)
In standard mode, only relay R1 is controlled by counter. The principle of control is the
same as in batcher mode, so read carefully chapter 6.4. The only difference in controlling of
the relay is the interpretation of parameters
“tr1”
and
“mr1”
.
In standard mode, after initialisation of counting cycle (point S, Figure 6.7a) relay output is
driven to
inactive . During control cycle relay outputs can change its state to active only when
the counter reach threshold value ( “Pr1” while upcounting, and „ 000 ” while downcounting).
Parameter “tr1” defines time during which relay R1 stays active after counter reach
threshold value .
