CHAPTER 6: SETPOINTS S4 CONTROLS
350 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL 6–119
LE1(16) ASSERTED
Range: On, Off
Default: Off
This setting defines the Logic Element state “On” or “Off” to be used as an output. The
asserted “On” selection provides an output “high” when the LE is "On". If asserted “Off” is
selected, then the LE output will be “high”, when the LE is “Off”.
TRIGGER INPUTS
Range: 2 to 8
Default: 3
This setting defines the number of trigger sources to be used in the menu of the Logic
Element. Up to eight trigger sources (inputs) can be selected.
TRIGGER SOURCE 1 (8)
Range: Off, Any input from the list of inputs
Default: Off
Each of the trigger sources is configurable by allowing the assigning of an input selected
from a list of inputs. This input can be a contact input, a virtual input, a remote input, or
an output flag from a protection, or control element. See the list of available inputs from
the table below.
TRIGGER LOGIC
Range: OR, AND, NOR, NAND, XOR, XNOR
Default: OR
This setting defines the gate types for the trigger sources (inputs).
PKP TIME DELAY
Range: 0 to 60000 ms in steps of 1 ms
Default: 0 ms
This setting specifies the pickup time delay before Logic Element operation.
DPO TIME DELAY
Range: 0 to 60000 ms in steps of 1 ms
Default: 0 ms
This setting specifies the time delay from a reset timer that starts upon expiry of the
pickup time delay and prolongs the operation of the Logic Element until this time
expires.
OUTPUT RELAY X
For details see Common setpoints .
NUMBER OF BLOCKS
Range: 2 to 4
Default: 3
This setting defines the number of blocks to be used in the menu of the Logic Element.
Up to four blocks can be selected.
BLOCK 1 (4)
Range: Off, Any input from the list of inputs
Default: Off
Each of the blocks is configurable by allowing the assigning of an input selected from a
list of inputs. This input can be a contact input, a virtual input, a remote input, or an
output flag from a protection, or control element, as well as an input from any of the
other seven logic inputs. See the list of available inputs from the table below
