d) By pressing the key 

ï

 the new selection is confirmed, and

the system goes back to the main settings change menu. The
following message is displayed:

[SETTINGS IN USE:]
[           SPARE]

6.2.2 Change main settings

a) Press the key 

ò

 or 

ñ

 until the following message is

displayed:

[SETTINGS  CHANGE]
[MAIN            ]

b) By pressing the key 

ð

 , you enter the main settings change

sub-menu, which contains all the parameters already listed in
§ 6.1.3.

c) By pressing the keys 

ò

 or 

ñ

, you can vertically scroll the sub-

menu, and by pressing  the key 

ð

  you can start changing the

displayed parameter. The change can be made by pressing
the keys 

ò

 or 

ñ

 .

d) By repeatedly  pressing the key 

ï

 anywhere in the sub-

menu, you go back to the main changing menu:

[SETTINGS  CHANGE]

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:

[SETTINGS  CHANGE]
[MAIN            ]

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

6.2.3 Change spare settings

a) Press the key 

ò

 or 

ñ

 until the following message is

displayed:

[SETTINGS 

CHANGE]

[SPARE          ]

b) By pressing the key 

ð

 , you enter the spare settings change

sub-menu, which contains all the parameters already listed in
§ 6.1.5.

c) By pressing the keys 

ò

 or 

ñ

 ,you can vertically scroll the sub-

menu, and by pressing  the key 

ð

  you can start changing the

displayed parameter. The change can be made by pressing
the keys 

ò

 or 

ñ

 .

The settings change procedure mirrors that described in the
example applying to the main settings.

d) By pressing the key 

ï

 anywhere in the sub-menu, you go

back to the main settings change menu:

[SETTINGS CHANGE]
[SPARE          ]

6.2.4 Set output relays

a) Press the key  

ò

 or 

ñ

 until the display shows:
