5-136 B90 LOW IMPEDANCE BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUALFLEXLOGIC CHAPTER 5: SETTINGS5TIMER 2= Virt Op 4ENDIn this expression, the virtual output 4 input to the four-input OR is listed before it is created. This is typical of a form offeedback, in this case, used to create a seal-in effect with the latch, and is correct.8. Always test the logic after it is loaded into the relay, in the same way as has been used in the past. Testing can besimplified by placing an "END" operator within the overall set of FlexLogic equations. The equations are evaluated upto the first "END" operator.The "On" and "Off" operands can be placed in an equation to establish a known set of conditions for test purposes, andthe "INSERT" and "DELETE" commands can be used to modify equations.5.5.5 FlexLogic equation editorSETTINGS FLEXLOGIC FLEXLOGIC EQUATION EDITORThere are 1,024 FlexLogic entries available, numbered from 1 to 1024, with default END entry settings. If a "Disabled"element is selected as a FlexLogic entry, the associated state flag is never set to ‘1’. Press the +/– key when editingFlexLogic equations to quickly scan through the major parameter types.5.5.6 FlexLogic timersSETTINGS FLEXLOGIC FLEXLOGIC TIMERS FLEXLOGIC TIMER 1(32)There are 32 identical FlexLogic timers available. These timers are used as operators for FlexLogic equations.TIMER 1 TYPE — Selects the time measurement unit.TIMER 1 PICKUP DELAY — Sets the time delay to pickup. If a pickup delay is not required, set this function to "0."TIMER 1 DROPOUT DELAY — Sets the time delay to dropout. If a dropout delay is not required, set this function to "0."5.5.7 Non-volatile latchesSETTINGS FLEXLOGIC NON-VOLATILE LATCHES LATCH 1(16) FLEXLOGIC EQUATION EDITOR FLEXLOGIC ENTRY 1:ENDRange: FlexLogic operands FLEXLOGIC ENTRY 1024:ENDRange: FlexLogic operands FLEXLOGIC TIMER 1 TIMER 1TYPE: millisecondRange: millisecond, second, minute TIMER 1 PICKUPDELAY: 0Range: 0 to 60000 in steps of 1 TIMER 1 DROPOUTDELAY: 0Range: 0 to 60000 in steps of 1 LATCH 1 LATCH 1FUNCTION: DisabledRange: Disabled, Enabled LATCH 1 ID:NV Latch 1Range: up to 20 alphanumeric characters LATCH 1 TYPE:Reset DominantRange: Reset Dominant, Set Dominant LATCH 1 SET:OffRange: FlexLogic operand
