4–100 869 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL
OUTPUTS CHAPTER 4: SETPOINTS
Virtual Outputs
The 869 relay is equipped with 32 virtual outputs that may be assigned for use via
FlexLogic. Virtual outputs not assigned for use are set to OFF (Logic 0).
A name can be assigned to each virtual output. Any
change of state to a virtual output can
be logged as an event if programmed to do so. Virtual outputs are resolved in each
protection pass via the evaluation of FlexLogic equations.
For example, if Virtual Output 1 is the trip signal from FlexLogic and the trip relay is used to
signa
l events, the settings would be programmed as follows:
Virtual Output 1 NAME: Tr
ip
Virtual Output 1 Events: Enabled
Path:
Setpoints > Outputs > Virtual Outputs > Virtual Outputs 1 (32)
NAME
Range: up to 13 alphanumeric characters
Default: VO 1
An alphanumeric name may be assigned to a virtual output for diagnostic, setting, and
event recording purposes.
EVENTS
Range: Disabled, Enabled
Default: Disabled
