located close to the zone boundary when small oscillations in the voltages or currents could inadvertently reset the
timer. Zone 1 does not need any drop out delay since it is sealed-in by the presence of current.

PHS DIST Z1 BLK:
This setting enables the user to select a FlexLogic operand to block a given distance element. VT
fuse fail detection is one of the applications for this setting.
Figure 5–58: PHASE DISTANCE ZONE 1 OP SCHEME
Figure 5–59: PHASE DISTANCE ZONE 2 OP SCHEME
For phase distance zone 2, there is a provision to start the zone timer with other distance zones or loop the pickup
flag to avoid prolonging phase distance zone 2 operation when the fault evolves from one type to another or
migrates from the initial zone to zone 2. Desired zones in the trip output function should be assigned to accomplish
this functionality.
** D60, L60, and L90 only. Other UR-series models apply regular current seal-in for zone 1.
