the first line displays the event number, the day, the month and
the year, whereas the second line lists the time, the minutes,
the seconds and thousandths of a second concerning the
event.
c) By pressing the key
ò
or
ñ
, select the event to be displayed.
Once the selection is made, press
ð
; thus, you enter the event
display sub-menu, and by pressing
ò
or
ñ
the following sub-
menu is scrolled:
tripped threshold
TRIP
value of resistance in
Ω
when the trip occurred
R_G
value of alternating current in A when the trip occurred
I
~
G
direct voltage value in mult.of Un when the trip occurredU-_G
d) By pressing
ï
anywhere in the sub-menu, you go back to
event display sub-menu; to display other events go through step
c) again. By pressing
ï
anywhere in the sub-menu you go back

6.1.9 Display output relays
a) Press
ò
or
ñ
until the display shows:
[OUTPUT RELAYS]
[ ]
b) By pressing
ð
you enter the sub-menu that displays the
allocation of the auxiliary output relays. The display shows:
[REL X12345]
[ON
↑↑↑↑↑
]
which stands for the enabling by normal energizing (
↑
) or de-
energizing (
↓
) of each relay.
Press
ò
to scroll across the whole submenu, the display unit
will show:
[R< START]
[REL X..3.5]
the first line displays the function that is associated with the
relay or relays listed in the second line.
By pressing the keys
ò
or
ñ
the sub-menu is scrolled across.
The functions that can be associated with the output relays are:
delayed start of first underresistance threshold
R< START
first underresistance threshold trip
R< TRIP
delayed start of sec. underresistance threshold R<< START
second underresistance threshold trip
R<< TRIP
delayed start of injected overcurrent threshold

6.1.10 Viewing digital inputs
a) Press the key
ò
or
ñ
until the display shows:
[ DIGITAL ]
[ INPUTS ]
b) By pressing the key
ð
you enter the sub-menu that lists the
allocation of digital inputs. The following message appears on
the display:
[IN DIG 123]
[ON

]
which stands for the enabling by normal energizing (
↑
) or de-
energizing (
↓
) of each input.
Press
ò
to scroll across the whole sub-menu, the display unit
will show:
[BLOC. R< ]
[IN DIG ...]
the first line contains the function that is associated with the
digital inputs listed in the second line.
By pressing the keys
ò
or
ñ
the sub-menu is scrolled.
The functions that may be associated with the inputs are:
