GE Multilin L90 Line Differential Relay 5-1555 SETTINGS 5.6 CONTROL ELEMENTS55.6.3 SELECTOR SWITCHPATH: SETTINGS !" CONTROL ELEMENTS !" SELECTOR SWITCH ! SELECTOR SWITCH 1(2)The Selector Switch element is intended to replace a mechanical selector switch. Typical applications include setting groupcontrol or control of multiple logic sub-circuits in user-programmable logic.The element provides for two control inputs. The step-up control allows stepping through selector position one step at atime with each pulse of the control input, such as a user-programmable pushbutton. The 3-bit control input allows settingthe selector to the position defined by a 3-bit word.The element allows pre-selecting a new position without applying it. The pre-selected position gets applied either after time-out or upon acknowledgement via separate inputs (user setting). The selector position is stored in non-volatile memory.Upon power-up, either the previous position is restored or the relay synchronizes to the current 3-bit word (user setting).Basic alarm functionality alerts the user under abnormal conditions; e.g. the 3-bit control input being out of range.ï SELECTOR 1 FULL RANGE: This setting defines the upper position of the selector. When stepping up through avail-able positions of the selector, the upper position wraps up to the lower position (Position 1). When using a direct 3-bitcontrol word for programming the selector to a desired position, the change would take place only if the control word iswithin the range of 1 to the SELECTOR FULL RANGE. If the control word is outside the range, an alarm is established bysetting the SELECTOR ALARM FlexLogicô operand for 3 seconds.ï SELECTOR 1 TIME-OUT: This setting defines the time-out period for the selector. This value is used by the relay inthe following two ways. When the SELECTOR STEP-UP MODE is ìTime-outî, the setting specifies the required period of# SELECTOR SWITCH 1#SELECTOR 1 FUNCTION:DisabledRange: Disabled, EnabledMESSAGE SELECTOR 1 FULLRANGE: 7Range: 1 to 7 in steps of 1MESSAGE SELECTOR 1 TIME-OUT:5.0 sRange: 3.0 to 60.0 s in steps of 0.1MESSAGE SELECTOR 1 STEP-UP:OffRange: FlexLogicô operandMESSAGE SELECTOR 1 STEP-UPMODE: Time-outRange: Time-out, AcknowledgeMESSAGE SELECTOR 1 ACK:OffRange: FlexLogicô operandMESSAGE SELECTOR 1 3BIT A0:OffRange: FlexLogicô operandMESSAGE SELECTOR 1 3BIT A1:OffRange: FlexLogicô operandMESSAGE SELECTOR 1 3BIT A2:OffRange: FlexLogicô operandMESSAGE SELECTOR 1 3BITMODE: Time-outRange: Time-out, AcknowledgeMESSAGE SELECTOR 1 3BIT ACK:OffRange: FlexLogicô operandMESSAGE SELECTOR 1 POWER-UPMODE: RestoreRange: Restore, Synchronize, Sync/RestoreMESSAGE SELECTOR 1 TARGETS:Self-resetRange: Self-reset, Latched, DisabledMESSAGE SELECTOR 1 EVENTS:DisabledRange: Disabled, Enabled
