The two LEDs on the top panel provide a convenient overview of the most
important status information, especially when the device is installed vertically. 

In the following sections we will use different terms to describe the behaviour
of the LEDs:

Blinking means, that the LED is switched on or off at regular intervals in
the respective indicated colour. 

Flashing means, that the LED lights up very briefly in the respective col-
our and stay then clearly longer (approximately 10x longer) switched off.

Inverse flashing means the opposite. The LED lights permanently in the
respective colour and is only briefly interrupted.

Flickering means, that the LED is switched on and off in irregular inter-
vals.

This LED indicates that the device is operational. After the device has been
switched on, it will flash green for the duration of the self-test. After the self-
test, either an error is output by a flashing red light code or the device starts
and the LED remains lit green.
