4, the serial interfaces, or a binary input. For
the latter, the binary input must be assigned to the function “
>Trig.Wave.Cap.”
(FNo 4). Triggering for the oscillographic recording then occurs when the input is en-
ergized. For example, an auxiliary contact of the circuit breaker or control switch may
be used to control the binary input for triggering.
An oscillographic recording that is externally triggered (that is, without a protective el-
ement pick-up or device trip) is processed by the device as a normal fault recording
with the exception that data are not given in the fault messages (trip log). The exter-
nally triggered record has a number for establishing a sequence.

window. Double click the entry
Test Wave Form in the list in the right part of the win-
dow to trigger the recording. See Figure 8-36.
A report is given in the bottom left region of the screen. In addition, message segments
concerning the progress of the procedure are displayed.
The DIGRA
