10.2.2 Confi guring the current transformer
ratios
The UMG 806 has 4 current measurement inputs
(I1 to I4) and one residual current measurement
input (I5).
· The default setting of all current transformer ra-
tios of the device (I1-I4 and I5) is 5 A / 5 A.
· The current transformer ratios must be confi g-
ured separately for current measurement inputs
I1-I3 , current measurement input I4 and resid-
ual current measurement input I5 (see table
"Confi guration of current transformer ratios").
· To confi gure the current transformer ratios,
switch to the confi guration mode of the device
as described in section „10.2 Confi guration“ on
page 47.
Parameters for confi guring the current transformer
ratios:
Address Designation
000 Current transformer primary, I1..I3
001 Current transformer secondary, I1..I3
010 Current transformer primary, I4
011 Current transformer secondary, I4
020 Residual current transformer primary,
I5
021 Residual current transformer second-
ary, I5

10.2.3 Example: Confi guring the current
transformer ratios I1-I3
· Press and hold buttons 1 and 2 simultaneously
for 1 s to switch between the display and confi g-
uration modes.
· Enter the code (password) in the display
using button 1 (confi rm or change digit position)
and button 2 (increment digit) (default setting
0000 - no password request).
· Parameter address 000 appears with the display
for confi guring the current transformer ratio - pri-
mary side I1 - I3.
· Confi gure, for example,
a primary side current
of 100 A.
· 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 1 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
and use button 1 to switch to the confi guration of
the decimal point.
· In the example here, place the decimal point after
the 1st digit.
· Confi rm your confi guration by pressing button 1.
· The 1st digit of the parameter address blinks.
· Go to parameter address 001 using buttons 1
and 2 as described.
· Use buttons 1 and 2 to confi gure the secondary
current (e.g. 5 A) in the same way as described
above.
· Finally, confi rm the confi guration by pressing
buttons 1 and 2 simultaneously.
· If necessary, confi gure the
current transformer
ratios of current measurement input I4
in the
same way (see table "Confi guration of current
transformer ratios").
· The device switches to the display mode
(1st measuring display).
