This ordering of parameters of an equation, where the gate (or “operator”) follows
the input (or “value”) is commonly referred to as “Postfix” or “Reverse Polish”
notation.
FIGURE 5–47: FlexLogic™ Example Implemented
Any equation entered in the 745 that does not make logical sense according to the
notation described here, will be flagged as a self-test error. The
SELF TEST ERROR:
FlexLogic Eqn
message will be displayed until the error is corrected.
Output Relays PATH: SETPOINTS !" S5 OUTPUTS ! OUTPUT RELAYS ! OUTPUT RELAY 1(8)
This section contains the settings (including the FlexLogic™ equation) to configure
output relays 1 to 8.
• OUTPUT 1(8) NAME: Press ENTER edit the name of the output. The text may be
changed from
Solid State Trip one character at a time, using the VA L U E keys.
Press ENTER to store the edit and advance to the next character position.
• OUTPUT 1(8) OPERATION: Select “Latched” to maintain the Output 1(8)
contacts in the energized state, even after the condition that caused the
contacts to operate is cleared, until a reset command is issued (or automatically
after one week). Select “Self-reset” to automatically de-energize the contacts
after the condition is cleared. The solid state output (Output 1) remains closed
until externally reset by a momentary interruption of current, unless wired in
parallel with an electromechanical relay (Outputs 2 to 8) in which case it turns
off when the relay operates.
• OUTPUT 1(8) TYPE: Select “Trip” to turn the Trip LED on or “Alarm” to turn
the Alarm LED on when this output operates. Otherwise, select “Control”. Note
