Engineering Manual
•
Prio 1 = RED
•
Prio 2 = YELLOW
•
Prio 3 = GREEN
•
When RED and YELLOW are ON at the same time, the LED will
illuminate in RED.
•
The operator's acknowledge for the LED signals is done for all three
signals (RED, YELLOW, GREEN) of the LED.
•
A reset of the LLEDs operates also on all three signals of the LEDs.
•
Follow-S
•
The LED illumination follows the status of the signal. The LED
illuminates steady (S).
•
Follow-F
•
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.
