· To save and fi nish, confi rm the confi guration by
pressing buttons 1 and 2 simultaneously.
· The device switches to the display mode (1st
measuring display).
· The current transformer confi guration is fi nished.
10.2.4 Example: Confi guring the current
transformer ratios of residual current
measurement input I5 (700:1)
· Press and hold buttons 1 and 2 simultaneously
for 1 s to switch between the display and confi g-
uration modes.
· Enter a password in the display using
button 1 (confi rm or change digit position) and
button 2 (increment digit) if necessary (default
setting
0000 - no password).
· The parameter address 000 appears.
· Use buttons 1 and 2 to go to parameter address
020 as described (see tab "Confi guration of cur-
rent transformer ratios").
· The primary value can be taken from your
residual current transformer (
e.g.
700 - with a
transformer ratio of 700:1 of your residual current
transformer).
· Confi gure
the primary side for residual current
measurement, e.g. 700.
· Go to the 1st digit (blinking) of the primary current
value by pressing button 1.
· Use button 2 to enter the value 0 for the 1st digit
and use button 1 to go to the 2nd digit (blinking).
· Use button 2 to enter the value 7 for the 2nd digit
and use button 1 to go to the 3rd digit (blinking).
· Use button 2 to enter the value 0 for the 3rd digit
and use button 1 to go to the 4th digit (blinking).
· Use button 2 to enter the value 0 for the 4th digit.
· Confi rm your confi guration by pressing button 1.
· The 1st digit of the parameter address blinks.
· Go to parameter address 021 using buttons 1
and 2 as described.
· Now confi gure the secondary side of the current
transformer ratio with buttons 1 and 2.
· Confi gure a 1 for the secondary value of your
residual current transformer, whereby this cor-
responds to the maximum value of the I5 mea-
suring range (40 mA - see section Technical data
- current measurement channel I5).
Example
A current transformer ratio confi guration of 700:1
and a secondary-side maximum value of the
measuring range of 40 mA results in a maximum
primary current of 28 A.
If there is now a secondary current of e.g. 3.57 mA
at measuring input I5, this corresponds to a prima-
ry current of 2.5 A.
