Auto-reclose start
initiation signals
The start signals AR1, AR2 and AR3 can be
used as start initiation signals for the desired
autoreclose shots. The initiation signal AR2 can
be programmed to be activated by the desired
start and operate signals of the overcurrent
module. The start signal AR3 can be programmed
to be activated by the desired start and operate
signals of the earth-fault module and the initia-
tion signal AR1 by the start and operate signals
of both the overcurrent module and the earth-
fault module.
Either the main settings or the second settings
can be selected as currently used settings. Switch-
ing between the main settings and the second
settings can be done in three different ways:
1) By command V150 over the serial communi-
cation bus
2) By an external control signal BS1, BS2 or
RRES (BS3)
3) Via the push-buttons of the relay module, see
submenu 4 of register A. When the value of
submenu 4 is 0 the main settings are used and
when the value of submenu 4 is 1 the second
settings are used.
The main and second settings can be read and
set via the serial bus using the S parameters.
Those settings only, which currently are used,
can be read and set with the push-buttons and
the display on the front panel. When the second
settings are used the indicators of the settings are
flashing.
Note!
If external control signals have been used for
selecting the main or second settings, it is not
possible to switch between the settings over the
serial bus or using the push-buttons on the front
panel.
Second settings
The LED operation indicators, the operation
code numbers of the display, the latched output
relays and the registers of the module can be
reset with the push-buttons on the front panel,
with an external control signal or by a command
via the serial bus, see table below.
