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\Inputs\Bi-
nary input1 (Binary input2...5)
menus.
When a binary input is programmed for remote trip acquisition, the
IN1 tON

IN5 tON

IN5 tOFF
time delays must be reset to zero; the
Logic
parameters (
ON/OFF
) must be programmed
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 bi-
nary input connected with-it.
All the parameters are common for A and B Profiles.
