ABB Relion 670 series - LED Operation Modes

• The same as LatchedAck-F-S but the LED starts with steady state and
flashes after acknowledgment.
• LatchedColl-S
• The LED illuminates in all cases in steady mode only
• The LED latches a signal change from OFF-ON until it is acknowledged
by the operator.
• The LED stays in steady mode when it is reset and the signal is still in
ON state.
• The LED is OFF only after the signal has changed to OFF state AND it
is reset by the operator via 'Clear' operation.
• LatchedReset-S
• This mode is used for all LEDs that are used to indicate a disturbance.
The LEDs will stay in the last state after the disturbance run time until
they are reset after a defined time.
• The timers are set in the Parameter Setting tool in the function block
LEDGEN.
