FUNCTION CHARACTERISTICS
Remote tripping
Preface
Some output relays may be programmed for remote trip function resulting from a command coming
from a binary input.
If a binary input is designed for remote trip acquisition, an output relay allocated to the same function
is triggered when the input (IN1 and/or IN2) is active.
Operation and settings
The
Remote trip
matching must be assigned to the selected binary inputs inside the
Set \ Board 1(2)
inputs \ Binary input IN1-1...(IN1-x)
menus.
When a binary input is programmed for remote trip acquisition, the
IN1 tON
,
IN2 tON
,
IN1 tOFF
and
IN2 tOFF
time delays must be reset to zero; the
Logic
parameters (
ON/OFF
) must be pro-
grammed in the same way of the related circuit connected with-it.
The
RemTrip-K
matching must be assigned to the selected output relays inside the
Set \ Remote
tripping
submenu; the same for addressing the LED indicators (
RemTrip-L
).
When output relays are programmed for remote tripping, the
t
TR
time delays must reset to zero;
the operation mode must be set with self reset (
No-latched
inside
Set \ Relays
submenu) and the
Logic
parameters (
Energized
/
De-energized
) must be programmed in the same way of the related
binary input connected with-it.
All the parameters are common for A and B Profi les
