Frequency Trigger
Overview of Functions
Frequency triggers start with exceeding or dropping below the set limiting values (level and gradient trigger)
in the fast-scan and slow-scan recorders. It is triggered on the power frequency.

NOTE
Frequency triggers are not available if there are no voltage measuring values assigned to the function
group Voltage-current 3-phase.
Structure of the Function
The function Frequency trigger is configurable in the 3-phase voltage and 3-phase voltage/current function
groups.
The structure of the function Frequency trigger is shown in the following figure:
[dwfnfreq-161012-01.tif, 1, en_US]
Figure 7-65 Structure/Embedding of the Function
A maximum of 3 function blocks of the same type can be entered or removed within the function. For unam-
biguous differentiating the function blocks automatically receive a sequential number in the name of the func-
tion block, for example, Frq. Trigger 1, Frq. Trigger 2, Frq. Trigger 3.
Each function block contains the level trigger
Max. trigger
and
Min. trigger
, as well as the gradient
trigger
dM/dt rise (/Filter time)
and
dM/dt drop active
of the corresponding measurand.
