3.2.11.1Blink code
A blink code displays detailed fault messages. A fault is cyclically displayed using up to 3 different blink sequences.
•The first blink sequence (approx. 10 Hz) indicates the fault display.
•After a pause a second blink sequence appears (approx. 1 Hz). The number of blink impulses gives the fault code.
•The third blink sequence (approx. 1 Hz) appears following a further pause. The number of blink pulses indicates the fault argument.
