3.1.5.3 Blink Code
Detailed fault messages are displayed with the aid of a blink code. A fault is
cyclically displayed with up to 3 blink sequences.
· The first blink sequence (approx. 10 Hz) starts the fault display.
· The second blink sequence (approx. 1 Hz) following a pause. The number
of blink pulses indicates the fault code.
· The third blink sequence (approx. 1 Hz) follows after a further pause. The
number of blink pulses indicates the fault argument.
