Note:
When Fb14 = ON (Fan operation feedback to BE2) and Fb26 = ON (BE in FSR), should a
fault occur, then “Fan malfunction” is registered in the FSR and not just the switching state of
BE2.
You can read the status register by keeping the enter key pressed down in the operating level
when the baud rate appears in the display. The display can be interpreted as shown below:
Number = Bit number in HR
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
This symbol
appears on
the right next to the number
