2 CALCULATION OF SETTINGS
1833: VBUSDEAD - Dead Bus Voltage
VBUSDEAD establishes the voltage at which the bus voltage must be less than before the functions requiring
dead bus supervision are allowed to operate. The voltage level can be set over a range of 0.1 to 130.0 V.
1834: VLINELIVE - Live Line Voltage
VLINELIVE establishes the voltage at which the line voltage must be greater than before the synchronism
check function and the functions requiring live line supervision are allowed to operate. The voltage level can be
set over a range of 0.1 to 130.0 V.
1835: VLINEDEAD - Dead Line Voltage
VLINEDEAD establishes the voltage at which the line voltage must be less than before the functions requiring
dead line supervision are allowed to operate. The voltage level can be set over a range of 0.1 to 130.0 V.
1836: LBUSDLINE - Live Bus Dead Line
With this setting, reclosing will be permitted if the line is dead (VLINEDEAD setting) and the bus is live (VBUS-
LIVE setting). If this operation is desired, set LBUSDLINE = YES, otherwise set LBUSDLINE = NO.
1837: DBUSLLINE - Dead Bus Live Line
With this setting, reclosing will be permitted if the line is live (VLINELIVE setting) and the bus is dead (VBUS-
DEAD setting). If this operation is desired, set DBUSLLINE = YES, otherwise set DBUSLLINE = NO.
1838: DBUSDLINE - Dead Bus Dead Line
With this setting, reclosing will be permitted if the line is dead (VLINEDEAD setting) and the bus is dead
(VBUSDEAD setting). If this operation is desired, set DBUSDLINE = YES, otherwise set DBUSDLINE = NO.
1839: DELTAV - Voltage Difference
DELTAV establishes the difference that must exist between the magnitudes of the bus and line voltages before
a DELTAVBLK output (Protection Setting 1840) is produced. DELTAV can be set over a range of 0.1 to 30.0 V.
1840: DELTAVBLK - Block Synch Check by DELTAV
DELTAVBLK can be set to YES or NO and establishes whether the synchronism check function is allowed to
operate. Set DELTAVBLK = YES to block the synchronism check function, otherwise set DELTAVBLK = NO.
Up to eight of the signals listed in the Index Tables given at the end of this section can be used to produce a
non-critical alarm signal (Index Number 52). This signal, when produced, will always be reported as an event
and it can also be programmed to drive one of the output relays if an external alarm is required.
1901: NCAIN1 - Non-Critical Alarm Input #1
1903: NCAIN3 - Non-Critical Alarm Input #3
1905: NCAIN5 - Non-Critical Alarm Input #5
1907: NCAIN7 - Non-Critical Alarm Input #7
Set these Protection Settings to one of the available Index numbers given in Table 2–7: INDEX NUMBERS –
scheme, recloser, & programmable logic on page 2–54.

1902: NCAIN2 - Non-Critical Alarm Input #2
1904: NCAIN4 - Non-Critical Alarm Input #4
1906: NCAIN6 - Non-Critical Alarm Input #6
1908: NCAIN8 - Non-Critical Alarm Input #8
