5.7 S5 OUTPUTS
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.
5 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

This section contains the settings (including the FlexLogic™ equation) to configure output relays 1 to 8.
• OUTPUT 1(8) NAME: Press
character at a time, using the
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 out-
put (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.
