Frequency Trigger

7.5.3.1

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
i i
Frequency triggers are not available if there are no voltage measuring values assigned to the function
group Voltage-current 3-phase.
7.5.3.2

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
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.
