● Dead time for system output current prewarning
An alarm for the prewarning threshold for the total current is only initiated if a continuous
system overload occurs, which is longer than the set dead time.
● General prewarning threshold for individual output current in MANUAL mode
Here, it is possible to define a common threshold value for all outputs, above which an
alarm is output.
Enter a value of "0 %" to deactivate the prewarning threshold.
● Dead time for alarm message 'Input voltage outside permitted range'
A buffer mode alarm is only initiated if the power continuously fails for a time that is
longer than the set dead time.
