Technical data

• 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.
