Write the following FlexLogic™ equation (EnerVista UR Setup example shown):
Both timers (Timer 1 and Timer 2) should be set to 20 ms pickup and 0 ms dropout.

Application Example 4:
A latching contact H1a is to be controlled from a single virtual output VO1. The contact should stay closed as long as VO1
is high, and should stay opened when VO1 is low. Program the relay as follows.

VIRTUAL OUTPUT 1(96)
There are 96 virtual outputs that may be assigned via FlexLogic™. If not assigned, the output will be forced to ‘OFF’ (Logic
0). An ID may be assigned to each virtual output. Virtual outputs are resolved in each pass through the evaluation of the
FlexLogic™ equations. Any change of state of a virtual output can be logged as an event if programmed to do so.
For example, if Virtual Output 1 is the trip signal from FlexLogic™ and the trip relay is used to signal events, the settings
would be programmed as follows:
„
VIRTUAL OUTPUT 1
„
VIRTUAL OUTPUT 1 ID
Virt Op 1
Range: Up to 12 alphanumeric characters

EVENTS: Disabled
Range: Disabled, Enabled
