secondary circuit. The
MINCB_OPEN
signal sets the
FUSEF_U
output signal to block all
the voltage-related functions when MCB is in the open state.
The
WARNING
output in the receiver is activated if the synchronization accuracy of the
sender or the receiver is worse than 4 μs. The output is held on for 10 seconds after the
synchronization accuracy returns within limits. If the protection relay supports frequency
adaptivity and it is enabled, the
WARNING
output is also activated when the adaptivity is
not ready.
The
WARNING
output is always internally active whenever the
ALARM
output is active.
The receiver activates the
WARNING
and
ALARM
outputs if any of the quality bits, except
for the derived bit, is activated. When the receiver is in the test mode, it accepts SMV
frames with test bit without activating the
WARNING
and
ALARM
outputs.
