Example of setting
Let us suppose we need to enable and set the rotor ground
threshold R< to 1015 Ohm starting from an initial setting of
990, OFF.
Go through steps a) and b)
Press
ò
or
ñ
until the threshold to be changed is selected on
display:
[R< OFF]
[R< 0990
Ω
]
Press
ð
to start changing the selected setting I>>>,the display
unit will show:
[R< OFF]
[R< 0990
Ω
]
Press
ò
or
ñ
to set it ON and the display will show:
[R< ON ]
[R< 0990
Ω
]
Press
ï
to move back to the beginning of the line. Thus, by
pressing
ò
, you may move to the second line.
Press
ð
to select the digit to be changed.
In our case, by pressing 4 times the key
ð
, the display unit will
show:
[R< ON ]
[R< 0990
Ω
]
Press
ñ
to increase the selected numberuntil the value re-
quired by our example is reached:
[R< ON ]
[R< 0995
Ω
]
Now, by pressing
ï
you select the third digit making up the
setting, the display unit will show:
[R< ON ]
[R< 0995
Ω
]
By pressing
ñ
the digit is changed (on reaching number 9 the
units will increase by 1) until the display unit shows:
[R< ON ]
[R< 1015
Ω
]
Press
ï
to move back to the beginning of the line and go back
to the main editing menu:

Warning:
In the event of the direct rated voltage setting range being
changed, please remember to move the internal jumper
(S20....S23) as follows:
jumper closed setting range
S20 30.00 - 300.00 V
S21 3.00 - 30.00 V
S22 0.30 - 3.00 V
S23 0.03 - 0.30 V
The movement of the jumper causes the setting to be changed,
as the latter is multiplied times 10
d
where d is the distance
between the old and the new jumper, for instance:
old setting
jumper S20
setting range 30-300 V
set Un 165 V
new setting
jumper S23
setting range 0.03-0.30 V
set Un 165 x 10 (20-23) = 0.16 V
