The amplitude of analog output signal on AO1-GND pins will be as calculated by the following formula.
AO1-GND =[
AO1 con.highlimit-AO1 con.lowlimit
x (Meas. value-(Min value x Multip.))]+ AO1 con. low limit
(Max value-Min value) x Multip.
E.g. 1 :
Assume that the following values have been assigned;
Input connection : V1(L-N) (phase-neutral voltage of phase 1)
Output connection : 0-5V
Min. value : 100V
Max. value : 200V
Multiplier : 1
Then, when measure is KLEA V1(L-N)=120V, the result will be as follows,
AO1-GND =[
5-0
x 120-(100x1) + 0 = 1V)] olur ( 200- KLEA V1(L-N)=185V the result will be as follows,
100)x1
AO1-GND =[
5-0
x 185-(100x1) + 0 = 4.25V olur. (200-
100)x1
E.g. 2 :
Assume that the following have been assigned;
Input connection : P tot.(total active power) Output connection: 4-20mA
Min. value : 600W
Max. value : 1000W
Multiplier : 1
Then, when measure is KLEA P tot. = 732W, the result will be as follows,
AO1-GND =[
20-4
x (732-(600x1))] + 4 = 5.28mA
(1000-600) x]
When measure is KLEA V1(L-N)=992W, the result will be as follows,
AO1-GND =[
20-4
x (992-(600x1)] + 4 = 19.68mA
(200-100)x1
E.g. 3 :
Assume that the following have been assigned;
Input connection : Q tot.(total reactive power) Output connection: -10 - 10V
Min. value : 1400VAr
Max. value : 1800VAr,
Multiplier : kilo
