The alarm words, warning words and extended status words can be read out via the serial com-
munication bus (or optional serial communication bus) for diagnosis. See also par. 16-90 - 16-94.
WARNING 1, 10 Volts low:
The 10 V voltage from terminal 50 on the con-
trol card is below 10 V.
Remove a portion of the load from terminal
50, since the 10 V supply is overloaded. Max.
15 mA or minimum 590 .
WARNING/ALARM 2, Live zero error:
The signal on terminal 53 or 54 is less than
50% of the value set in par. 6-10, 6-12, 6-20
