5.7 INPUTS / OUTPUTS
Some events can be programmed to latch the faceplate LED event indicators and the target message on the display. Once
set, the latching mechanism will hold all of the latched indicators or messages in the set state after the initiating condition
has cleared until a RESET command is received to return these latches (not including FlexLogic™ latches) to the reset
state. The RESET command can be sent from the faceplate RESET button, a remote device via a communications chan-
nel, or any programmed operand.
When the RESET command is received by the relay, two FlexLogic™ operands are created. These operands, which are
stored as events, reset the latches if the initiating condition has cleared. The three sources of RESET commands each cre-
ate the FlexLogic™ operand "RESET OP". Each individual source of a RESET command also creates its individual oper-
and RESET OP (PUSHBUTTON), RESET OP (COMMS) or RESET OP (OPERAND) to identify the source of the
command. The setting shown above selects the operand that will create the RESET OP (OPERAND) operand.
