The fan monitoring parameters are entered to this window.
A) Converter Assignment
Which fan will be controlled by which converter can be selected here.
0 = no fan, or fan monitoring not activated for this fan
1.16 = number of the desired frequency converter
20.60 = entry of a fixed frequency setpoint for this fan
B) Fan_Count
The number of defective fans is displayed here.
C) Fan_No.
The index number of the defective fan is displayed. In the event of more
than one defect, the highest index number is displayed.
D) Fan supervision
Input for tolerance of the fan supervision. Standard value is 2 Hz. When
exceeding the allocated frequency by 2 Hz an alarm fan supervision fail-
ure is triggered off.
