5.9.3 Adjustment of the Trigger Event
There is the choice between four different trigger events:
P_UP (PickUP)
Data saving begins when a general
activation is recognised.
TRIP
Data saving begins when a general
trip is recognised.
A_PI (After Pickup) Data saving begins when the last acti-
vation threshold is undershot (recog-
nises, for instance, CB failure protec-
tion)
TEST
Data saving is activated when push-
buttons <+> and <-> are pressed
simultaneously (immediately upon
pressing the buttons). For recording
time, the mode TEST is displayed.
5.9.4 Pre-Trigger time (T
vor
)
The time T
pre
defines the period to be saved prior to the
trip event. This time can be set between 0.05 s and the
max. recording time (2, 4 or 8 s). With push-buttons
<+> and <-> the values can be changed and with
<ENTER> they can be saved.
5.10 Setting of the clock
When date and time are set, the LED „
!
“ is on. The fol-
lowing method is used:
Date:
year
Y=00
month
M=00
day
D=00
time:
hour
h=00
minute
m=00
second
s=00
Immediately when the supply voltage is applied the
clock starts with the respective date and time. The time
is buffered against short-term voltage failures (min. 6
minutes).
Note:
The window for setting the clock is behind the measur-
ing value reading. Access to the window via push-
button <SELECT/RESET>.
