• Logical 1 on functional input BLOCK inhibits the output START signal
instantaneously.
• The INHIBIT internal signal is activated, if the power swing has been detected
and the measured impedance remains within its operate characteristic for the
time, which is longer than the time delay set on tR2 timer. It is possible to
disable this condition by connecting the logical 1 signal to the BLKI01
functional input.
• The INHIBIT internal signal is activated after the time delay, set on tR1 timer,
if an earth-fault appears during the power swing (input IOCHECK is high) and
the power swing has been detected before the earth-fault (activation of the
signal I0CHECK). It is possible to disable this condition by connecting the
logical 1 signal to the BLKI02 functional input.
• The INHIBIT logical signals becomes logical 1, if the functional input
I0CHECK appears within the time delay, set on tEF timer and the impedance
has been seen within the outer characteristic of ZMRPSB operate
characteristic in all three phases. This function prevents the operation of
ZMRPSB function in cases, when the circuit breaker closes onto persistent
single-phase fault after single-phase autoreclosing dead time, if the initial
single-phase fault and single-phase opening of the circuit breaker causes the
power swing in the remaining two phases.
