1. Set
2. Activate the switch onto fault BC input.
During normal operating conditions, the BC input is de-energized.
3. Apply a three-phase fault condition corresponding to a fault at approximately 45% of the
line or with impedance at 50% of the used zone setting and current greater than 30% of
IBase .
The ZACC input is activated.
4. Check that the TRIP output, external signals and indication are obtained.

4. Apply a three-phase fault condition corresponding to a fault at approximately 45% of the
line or with impedance at 50% of the used zone setting and current greater than 30% of
IBase .Apply a two-phase fault condition corresponding to a fault at approximately 45%
of the line or with impedance at 50% of the used zone setting and current greater than
30% of
The ZACC input is activated.
5. Check that the correct TRIP output, external signals and indication are obtained.

Initiating ZCVPSOF automatically and setting mode to UILevel

1. Set
2. Deactivate the switch onto fault BC input.
3. Set the current and voltage inputs to lower than
4. Apply the three-phase currents in such a way that the magnitudes are greater than
and the three-phase voltages in such a way that the magnitudes and lower than
least for the duration of the

Values of the logical signals for PHPIOC are available on the local HMI under Main menu/
Tests/Function status/Current protection/InstPhaseOverCurrent(50,3I>>)/
PHPIOC(50;3I>>):x, where x = 1, 2, and 3.
The Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
