Example for calculating the parameters for the range start value and range end value
The following measured values and parameters are given as an example:
● Output signal type: 4 ... 20 mA
● Measured value: Phase current average (%)
● Range start value = desired start value (e.g. 50%) / factor of the measured value
● Range end value = desired end value (e.g. 200%) / 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%) → 16
– Range end value (e.g. 200% / 3.125%) → 64
In this example, a pointer instrument indicates 50% (start value) at the left stop and 200%
(end value) at the right stop. You can divide the scale of the pointer instrument between the
left stop and the right stop, depending on the desired resolution.
Result
The output signal of the analog output has been adjusted.
