RESETTING
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 channel,
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
RESET OP
FlexLogic™ operand. Each individual source of a RESET command also creates its individual operand
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.

DIRECT INPUT 1(32)
These settings specify how the direct input information is processed. The
DIRECT INPUT 1 NAME
setting allows the user to
assign a descriptive name to the direct input. The
DIRECT INPUT 1 DEVICE ID
represents the source of direct input 1. The
specified direct input is driven by the device identified here.
The
DIRECT INPUT 1 BIT NUMBER
is the bit number to extract the state for direct input 1. Direct Input 1 is driven by the bit
identified as
DIRECT INPUT 1 BIT NUMBER
. This corresponds to the direct output number of the sending device.
The
DIRECT INPUT 1 DEFAULT STATE
represents the state of the direct input when the associated direct device is offline. The
following choices are available:
• Setting
DIRECT INPUT 1 DEFAULT STATE
to “On” value defaults the input to Logic 1.
• Setting
DIRECT INPUT 1 DEFAULT STATE
to “Off” value defaults the input to Logic 0.
• Setting
DIRECT INPUT 1 DEFAULT STATE
to “Latest/On” freezes the input in case of lost communications. If the latest
state is not known, such as after relay power-up but before the first communication exchange, the input will default to
Logic 1. When communication resumes, the input becomes fully operational.
• Setting
DIRECT INPUT 1 DEFAULT STATE
to “Latest/Off” freezes the input in case of lost communications. If the latest
state is not known, such as after relay power-up but before the first communication exchange, the input will default to
Logic 0. When communication resumes, the input becomes fully operational.
