6.4. CONTROL OF THE RELAY OUTPUTS (BATCHER MODE)
Controlling of external devices due to state of the counter is realised using relay outputs.
Operation of relay output is described by parameters:
“dir”
,
“Pr1”
,
“Pr2”
,
“tr1”
,
“tr2”
,
“mr1”
,
“mr2”
,
“dLy”
and
“Ar”
.
6.4.1. Driving of the relays during upcounting
The mode of relays operation during upcounting (parameter “dir” = ”UP” ) for example
settings is showed in figure 6.4 ( AUTORESET function is inactive) and in figure 6.5 (active
AUTORESET
function).
Description:
S
- initialisation of the counting cycle,
A, B, D, E - points while counter exceeds selected value,
C, F - manual initialisation of counting cycle
t
X1
, t
X2
- idle time ( device is waiting for manual initialisation),
t
Z
- delay of relay reaction,
