2 CALCULATION OF SETTINGS 2.3 PROTECTION SETTINGS
1827: SP3PDELAY1 - Supervise First Three-pole Reclose
SP3PDELAY1 can be set to YES or NO and establishes whether the first three-pole reclose (if selected) following an initial
three-pole trip will be supervised by the synchronism check function.
1828: SP3PDELAY2 - Supervise Second Three-pole Reclose
SP3PDELAY2 can be set to YES or NO and establishes whether the second three-pole reclose (if selected) following an
initial three-pole trip will be supervised by the synchronism check function.

1829: SP3PDELAY3 - Supervise Third Three-pole Reclose
SP3PDELAY3 can be set to YES or NO and establishes whether the third three-pole reclose (if selected) following an initial
three-pole trip will be supervised by the synchronism check function.
1830: SP3PDELAY4 - Supervise Fourth Three-pole Reclose
SP3PDELAY4 can be set to YES or NO and establishes whether the fourth three-pole reclose (if selected) following an ini-
tial three-pole trip will be supervised by the synchronism check function.
1831: SYNCMANCLS - Supervise Manual Close
SYNCMANCLS can be set to YES or NO and establishes whether manual closing of the breaker will be supervised by the
synchronism check function.
1832: VBUSLIVE - Live Bus Voltage
VBUSLIVE establishes the voltage at which the bus voltage must be greater than before the synchronism check function
and the functions requiring live bus supervision are allowed to operate. The voltage level can be set over a range of 0.1 to
130.0 volts.
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 level which the line voltage must be greater than before the synchronism check function and
functions requiring live line supervision operate. The voltage level can be set from 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 (VBUSLIVE 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 (VBUSDEAD setting).
If this operation is desired, set DBUSDLINE = 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 set-
ting). 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 bus and line voltage magnitudes before a DELTAVBLK out-
put (Protection Setting 1840) is produced. DELTAV can be set from 0.1 to 30.0 volts.
