10.3. Setting up the instrument (example)
It is an additional example for Chapter 7. Setting-up. It
helps to understand the setting of values through a practical
example. The steps of the whole setting you will find in
Chapter 7..
There is a AC Voltage Meter with 250 VAC input range. The
voltage value in the power network 0-1000 VAC, voltage
transformer ratio: UX = 4.
The DT4240 xx xx xx xx have 4-20 mA analog output option
Min value: 0 VAC - 4 mA, max value 1000 VAC - 20 mA
In a case of U > 500 VAC, the limit No.1 should be close.
The DT4240 xx xx xx xx parameter settings:
•
The voltage transformer ratio: UX = 4.
•
The physical value assigned for the 4 mA current output:
0000.0 VAC.
•
The physical value assigned for the 20 mA current output:
1000.0 VAC.
