CHAPTER 6: SETPOINTS S4 CONTROLS
350 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL 6–117
Virtual inputs
There are 32 virtual inputs that can be individually programmed to respond to input
commands entered via the relay keypad, or by using communication protocols.
PATH:
SETPOINTS > S4 CONTROLS > VIRTUAL INPUTS.
VIRTUAL INPUT 1
Range: Off, On
Default: Off
The state of each virtual input can be controlled under
SETPOINTS > S4 CONTROL >
VIRTUAL INPUTS
menu. For this purpose, each of the virtual inputs selected for control need
be “Enabled” under SETPOINTS > S5 INPUTS/OUTPUTS > VIRTUAL INPUTS, and its type “Self-
Reset or Latched” specified.
If Self-Reset type was selected, entering “On” command will lead to a pulse of one
protection pass. To prolong the time of the virtual input pulse, one can assign it as a
trigger source to a Logic Element with a dropout timer set to the desired pulse time. If
“Latched” type is selected, the state of the virtual input will be latched, upon entering “On”
command.
Refer to the logic diagram in the
S5 INPUTS/OUTPUTS > VIRTUAL INPUTS chapter for more
details.
