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.

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
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
