BS/BE LEDs
Indicator state
Definition
On
The indicator is constantly on.
Off
The indicator is constantly off.
Blinking
The indicator turns on and off with a frequency of approximately 2,5 Hz: on for approximately
200 ms, followed by off for 200 ms. Red and green LEDs shall be on alternately.
Flickering
The indicator turns on and off with a frequency of approximately 10 Hz: on for approximately 50
ms, followed by off for 50 ms. Red and green LEDs shall be on alternately.
Single Flash
The indicator shows one short flash (approximately 200 ms) followed by a long off phase
(approximately 1,000 ms).
Double Flash
The indicator shows a sequence of two short flashes (each approximately 200 ms), separated
by a short off phase (approximately 200 ms). The sequence is finished by a long off phase
(approximately 1,000 ms).
Triple Flash
The indicator shows a sequence of three short flashes (each approximately 200 ms), separated
by a short off phase (approximately 200 ms). The sequence is finished by a long off phase
(approximately 1,000 ms).
