5-60 C60 Breaker Management Relay GE Multilin5.5 GROUPED ELEMENTS 5 SETTINGS5b) AUXILIARY UV1 (AUXILIARY UNDERVOLTAGE: ANSI 27X)PATH: SETTINGS !" GROUPED ELEMENTS ! SETTING GROUP 1(8) !" VOLTAGE ELEMENTS !" AUXILIARY UV1This element is intended for monitoring undervoltage conditions of the auxiliary voltage. The PICKUP selects the voltagelevel at which the time undervoltage element starts timing. The nominal secondary voltage of the auxiliary voltage channelentered under SETTINGS " SYSTEM SETUP ! AC INPUTS "! VOLTAGE BANK X5 / AUXILIARY VT X5 SECONDARY is the p.u. baseused when setting the pickup level.The DELAY setting selects the minimum operating time of the phase undervoltage element. Both PICKUP and DELAY settingsestablish the operating curve of the undervoltage element. The auxiliary undervoltage element can be programmed to useeither Definite Time Delay or Inverse Time Delay characteristics. The operating characteristics and equations for both Defi-nite and Inverse Time Delay are as for the Phase Undervoltage Element.The element resets instantaneously. The minimum voltage setting selects the operating voltage below which the element isblocked.Figure 5ñ24: AUXILIARY UNDERVOLTAGE SCHEME LOGIC# AUXILIARY UV1#AUX UV1FUNCTION: DisabledRange: Disabled, EnabledMESSAGE AUX UV1 SIGNALSOURCE: SRC 1Range: SRC 1, SRC 2,..., SRC 6MESSAGE AUX UV1 PICKUP:0.700 puRange: 0.000 to 3.000 pu in steps of 0.001MESSAGE AUX UV1 CURVE:Definite TimeRange: Definite Time, Inverse TimeMESSAGE AUX UV1 DELAY:1.00 sRange: 0.00 to 600.00 s in steps of 0.01MESSAGE AUX UV1 MINIMUM:VOLTAGE: 0.100 puRange: 0.000 to 3.000 pu in steps of 0.001MESSAGE AUX UV1 BLOCK:OffRange: FlexLogicô operandMESSAGE AUX UV1TARGET: Self-resetRange: Self-reset, Latched, DisabledMESSAGE AUX UV1EVENTS: DisabledRange: Disabled, Enabled827849A2.CDRFLEXLOGIC OPERANDSAUX UV1FUNCTION:AUX UV1 BLOCK:AUX UV1 SIGNALSOURCE:AUX UV1 MINIMUMVOLTAGE:AUX UV1 DPOAUX UV1 OPAUX UV1 PKPRUNSETTINGSETTINGAUX UV1 CURVE:AUX UV1 DELAY:AUX UV1 PICKUP:SETTINGEnabled=1Disabled=0SETTINGSETTINGOff=0AUX VOLT Vx Vx MinimumVx PickuptV<<ANDwww .
