5.4.13 Setting of parity (applies for
Modbus Protocol only)
The following three parity settings are possible :
•
"even" = even parity
•
"odd" = odd parity
•
"no" = no parity check
The setting can be changed by push buttons <+> and
<-> and saved by pressing <ENTER>.
5.5 Parameter for the fault recorder
5.5.1 Adjustment of the fault recorder
The
MRF3
is equipped with a fault recorder (see chap-
ter 3.1.5). Three parameters can be determined.
5.5.2 Type of fault recorder
The normal or extended recording time can be se-
lected by parameter "Number of Recordings".
5.5.3 Number of the fault recordings
The max. storage time for the normal recording time is
16s at 50 Hz and 13.2 at 60 Hz. For the extended
recording time the storage time is 64s at 50 Hz and
53.2s at 60Hz.

5.5.4 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”.
5.5.5 Pre-trigger time (T
pre
)
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. 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=00
Day D=00
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.
