5.5.2 Number of the fault recordings
The max. recording time is 16 s at 50 Hz or 13.33 s
at 60 Hz.
The number of max. recordings requested has to be
determined in advance. There is a choice of (1)* 2,
(3)* 4 or (7)* 8 recordings and dependent on this the
duration of the individual fault recordings is defined,
i.e.
(1)* 2 recordings for a duration of 8 s (with 50 Hz)
(6.66 s with 60 Hz)
(3)* 4 recordings for a duration of 4 s (with 50 Hz)
(3.33 s with 60 Hz)
(7)* 8 recordings for a duration of 2 s (with 50 Hz)
(1.66 s with 60 Hz)
* is written over when a new trigger signal arrives
Caution:
If the fault recorder is used, the frequency should be
set to f = 50 Hz or f = 60 Hz (refer to chapter 5.3.3).
5.5.3 Adjustment of trigger occurences
There is a choice between four different occurences:
P_UP (PickUP) Storage is initiated after recognition
of a general activation.
TRIP Storage is initiated after a trip has
occured.
A_PI (After Pickup) Storage is initiated after the last
activation threshold was fallen
short of.
TEST Storing is activated by simultaneous
actuation of the keys <+> and <->.
During the recording time the
display shows “Test”.
5.5.4 Pre-trigger time (Tvor)
By the time T
pre
it is determined which period of time
prior to the trigger occurence should be stored as well.
It is possible to adjust a time between 0.05s and the
max. recording interval (2, 4 and 8s at 50 Hz and
1.33; 3.33 and 6.66 s at 60 Hz). With keys <+>
and <-> the values can be changed and with
<ENTER> be saved.
5.6 Date and time
5.6.1 Adjustment of the clock
When adjusting the date and time, LED
"
lights up.
The adjustment method is as follows:
Date : Year Y=00
Month M=01
Day D=01
Time : Hour h=00
Minute m=00
Second s=00
The clock starts with the set date and time as soon as
the supply voltage is switched on. The time is safe-
guarded against short-term voltage failures (min. 6
minutes).
Note:
The window for parameter setting is located behind
the measured value display. The parameter window
can be accessed via the <SELECT/RESET> key.
