10.2.5 Confi guring the voltage transformer
ratios
The UMG 806 has 4 voltage measurement inputs
(V1 - V3 and VN). Of these, you can confi gure the
inputs L1 (V1) to L3 (V3).
· The default setting of all voltage transformer
ratios of the device (V1-V3) is 380 V / 380 V.
· The voltage transformer ratios must be confi g-
ured for the voltage measurement inputs V1-V3
(L1-L3).
· To confi gure the voltage 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 voltage transformer
ratios:
Address Designation
002 Voltage transformer primary, V1..V3
(L1..L3).
003 Voltage transformer secondary, V1..
V3 (L1..L3).

10.2.6 Example: Confi guring the voltage
transformer ratios
· 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).
· The parameter address 000 appears.
· Go to parameter address 002 using buttons 1
and 2 as described.
· The display for confi guring the primary side of the
voltage transformer ratio appears. For example,
confi gure
a primary voltage of 800 V.
· Go to the 1st digit (blinking) of the primary volt-
age 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 4 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 003 using buttons 1
and 2 as described.
· Use buttons 1 and 2 to confi gure the secondary
voltage (e.g. 400 V) in the same way as described
above.
· Finally, confi rm the confi guration by pressing
buttons 1 and 2 simultaneously.
· The device switches to the display mode (1st
measuring display).
