comparison can only be performed if a logic ‘1’ is provided at the ‘RUN’ input.
The relationship between a setpoint and input parameter is indicated by the following
symbols: “<” (less than), “>” (greater than), etc.
•
Pickup and Dropout Time Delays
: Shown as a block with indication of two timers –
the t
PKP
(Pickup Delay), and t
DPO
(Dropout Delay).
•
LED Indicators
: Shown as the following schematic symbol
(X)
.
•
Logic
: Described with basic logic gates (AND, OR, XOR, NAND, NOR). The inverter
(logical NOT), is shown as a circle:
O
•
FlexLogic operands
: Shown as a block with a heading labeled ‘FLEXLOGIC OPERANDS’.
Each feature produces output flags (operands) which can be used further for creating
logic in the FlexLogic equation editor, or Trip Bus, or can be directly assigned to trigger
an output. The operands from all relay features constitute the list of FlexLogic
operands.
