5 SETPOINTS
• TRACE TRIG FLEXLOGIC 01 to 10: The following 10 messages are the parameters of the FlexLogic™ equation for
trace memory triggering as described in the introduction to FlexLogic™.
The Trace Memory default FlexLogic™ is as follows:
TRACE TRIG FLEXLOGIC 01: Any Element PKP
TRACE TRIG FLEXLOGIC 02 to 12: END

VIRTUAL OUTPUT 1
[ENTER] for more
Virtual outputs are FlexLogic™ equations whose output (or result) can be used as inputs to other equations. The 745 has
five (5) virtual outputs. One application of these outputs may be to contain a block of logic that is repeated for more than
one output.
This section contains the FlexLogic™ equations to configure Virtual Outputs 1 to 5. The setpoints describe the parameters
of the FlexLogic™ equation for Virtual Output 1(5) as described in the introduction to FlexLogic™.

TIMER 1
[ENTER] for more
Protection and monitoring elements already have their own programmable delay timers, where they are required. For addi-
tional flexibility, ten (10) independent timers are available for implementing custom schemes where timers are not available.
For example, a pickup delay timer may be required on a logic input; or, a single delay timer may be required on the output
of a block of logic.
• TIMER 1(10) START: Select the FlexLogic™ entry which, when operated or asserted, will start Timer 1(10).
• TIMER 1(10) PICKUP DELAY: Enter the delay time during which the start condition for Timer 1(10) must remain oper-
ated or asserted, before the timer will operate.
• TIMER 1(10) DROPOUT DELAY: Enter the delay time after which the start condition for Timer 1(10) must remain not
operated or not asserted, before the timer will stop operating.
