•
The LED illumination follows the status of the signal. The LED illuminates
flashing (F).
•
LatchedAck-F-S
•
The LED latches the signal change OFF-ON and flashes (F) until it is
acknowledged.
•
When the signal is still ON at the time the signal is acknowledged the LED
changes to steady (S) mode.
•
When the signal has already changed to OFF before the time it is
acknowledged, the LED turns to OFF.
•
LatchedAck-S-F
•
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 Parameter Setting tool in the function block LEDGEN.
