CHAPTER 5: SETTINGS INPUTS/OUTPUTS

D30 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 5-309

5.9.5.2 Graphical front panel

SETTINGS  INPUTS/OUTPUTS  RESETTING

Some events can be programmed to latch the front panel LED event indicators, target messages, and/or graphical front

panel annunciator windows. Once set, the latching mechanism holds the latched indicators, messages, or windows 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 where the initiating condition has cleared. The

RESET command can be sent from the

front panel RESET button, a remote device via a communications channel, or any selected operand. The Modbus execute

function 05h with operation code 1 command is also available to perform the same function as the front panel RESET key.

RESET OPERAND — The three sources of RESET commands each activates the RESET OP FlexLogic operand. Each individual

source of a

RESET command also activates its individual operand RESET OP (PUSHBUTTON), RESET OP (COMMS), or RESET OP (OPERAND) to

identify the source of the command. Each of these three operands generates an event in the event record when activated.

The

RESET OPERAND setting here selects the operand that activates the RESET OP (OPERAND) operand.

RESET ANNUNCIATOR — Used to select a FlexLogic operand that when activated acknowledges/resets all annunciator

windows on the graphical front panel. The other methods to acknowledge/reset annunciator windows include:

• On the displayed page, press the RESET pushbutton with none of the annunciator windows selected to acknowledge/

reset all annunciator windows on that page

• To acknowledge/reset a specific annunciator window, use the Up, Down, Left and Right pushbuttons to select the

window, and press the RESET or ENTER pushbutton

• All annunciator windows can be reset remotely by programming a Virtual Input (for example Virtual Input 1) as the

input to the

RESET ANNUNCIATOR setting. Then the Modbus execute function 05h with operation code 1000h command

(or function 10h with address 400h) is used to set the state of Virtual Input 1.

For the

RESET ANNUNCIATOR setting, the RESET ANCTR OP FlexLogic operand is activated by the two sources of RESET

command, operand source and manual source. Each individual source of a

RESET ANNUNCIATOR command also activates

its individual operand RESET OP (OPRD) or RESET ANCTR OP (MNUL) to identify the source of the command. Each of these two

operands generates an event in the event record when activated. The setting here selects the operand that activates the

RESET ANCTR OP (OPRD) operand. The RESET pushbutton on the front panel or the reset command from the software

activates the RESET ANCTR OP (MNUL) operand.
