Description
Output signal type
Via the "Output signal type" parameter, you can define with what type of signal the
analog value will be output (current or voltage).
x
Deactivated
x
4 - 20 mA (factory setting)
x
0 ... 10 mA
Range start value
With parameters "Range start value" and "Range end value", you can define which
value of the analog value to be output corresponds to the lower output signal value
and which to the upper output signal value. The respective value depends on the
coding of the measured value.
Factory setting:
x
Range start value: 0
Setting of the analog range, e.g. 4 mA = 0
x
Range end value: 96
Setting of the analog range, e.g. 20 mA = 96, corresponds to 300 % of the
average phase current (%).

Example for calculating the parameters for the range start value and range end value
In this example, a pointer instrument indicates the measured value "Phase current average
(%)" at the left stop with 50% (start value) and the right stop 200% (end value). You can
divide the scale of the pointer instrument between the left stop and the right stop, depending
on the desired resolution.
The following parameters are given as examples at this point:
Ⴠ
Output signal type: 4 ... 20 mA
Ⴠ
Range start value = desired start value (%) / factor of the measured value
Ⴠ
Range end value = desired end value (%) / factor of the measured value
Procedure
1.
Parameterize the output signal type, e.g. 4 ... 20 mA.
2.
Parameterize the range start value and the range end value taking the following factor
into account:
–
Range start value (e.g. 50% / 3.125%)
ൺ
16
–
Range end value (e.g. 200% / 3.125%)
