Figure 44: LHMI: LED operation mode
650 series
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.
The LED illumination follows the status of the signal. The LED illuminates steady (S).
The LED illumination follows the status of the signal. The LED illuminates flashing (F).
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.
The same as LatchedAck-F-S but the LED starts with steady state and flashes after
acknowledgment.
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.
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.
