a stable reading, the average of the variations of the input signal.
When the filter is activated in a value between [?1??] and [?E??] , the response time of the instrument
can have a delay between 300 ms ( in level 1) and 30 s (in level E), because for a higher filter value,
the processor presents the reading a higher number of readings.
If the average filter is not activated [?0??] , the variation on the measuring signal line can be
displayed as variations of the reading, as well as altering the internal calculation process of the PID
and other operations.
The recommended filter levels are:
1 to 5 Fast response processes requiring to observe its variation.
6 to 9 Slow response processes not requiring to observe its variation. Measurement of
Temperature, pH, etc.
A to F Processes with self oscillation or using sensitive sensors. Pressure, Level, Flow, etc.
● Range Limits setting:
It is used to limit the operating range of Thermocouples or Pt 100 inputs, within the its total
range. Allows to associate a range for a 0...4-20 mA input signal of a transmitter.
- In [ConF] [AI 1] or [AI 2] in parameters [P 05] and [P 06] introduce the low and high range
limits in [nn nnnn].
Possible limits: -32000 to 32000 points (without decimals).
Example:
For an input “K” the total range by default is -200 to 1300 °C. If it is required to reduce this
limit for example from 0 to 1200 °C introduce in:
