Assignment of the AR functions
The last activation of the <SELECT/RESET> key in the
relay assignment mode will activate the AR assignment
mode.
•
The accompanied LEDs indicate which functions will
be assigned to the individual protection stages for pa-
rameter setting before the 1
st
AR.
•
Actuation of the <+> <-> keys permits switching over
between "BLOC", "TIME" or "FAST".
Here the following functions are activated or deacti-
vated one after the other.
1.
"BLOC" blocking of the protective functions.
2.
"TIME" tripping of the individual protective functions
with set delay time.
3.
"FAST" tripping with Fast Trip function.
•
Actuation of the <ENTER> key with subsequent one-
time entry of the pass word will store the altered
value.
•
Actuation of the <SELECT/RESET> key will assign the
tripping function before the 1
st
AR, one after the other
to the individual protection stages.
•
After this adjustment the parameters are set for activa-
tion of the 1
st
AR.
•
The accompanied LEDs indicate which protective
functions are available for parameter setting for the
first AR.
•
Actuation of the <+> <-> keys permits switching over
between "YES" and "NO". "YES" means that the se-
lected protection function will trigger an AR.
•
Actuation of the <ENTER> key with subsequent one-
time entry of the password will store the altered value.
•
Actuation of the <SELECT/RESET> key the protective
functions are, one after the other, assigned to the first
AR.
The following table shows all parameters that have to
be set. After each group the setting changes between
parameter set 1 and 2.
