Continued from the previous page.
• If the number of digits below the decimal point is changed in the decreasing direction, the decreased
number of digits is omitted.
Example: Suppose set SLH is 99.99, if change decimal point position from 0 to 2.
The figures below the decimal point are omitted,
and as a result SLH becomes 99.
In the above example, it the position of the decimal point is returned to 2 from 0, SLH
becomes 99.00.
• Set SLL and SLH so that SLL may not be equal to SLH when the position of the decimal point is
changed. Otherwise malfunction may result.
Example: When the position of the decimal point is changed to 0 at SLL=999.1 and SLH=999.9

When changed parameter of setting limiter [high limit/low limit]
When change setting limiter [high limit/low limit], all the set value of a list shown below is initialized.
Set it in value to use once again. However no change is made if the set value is within the range
changed.

Example: For temperature input, voltage/current inputs
If the setting is made so that the span becomes narrower, there may be a case where the related set
value becomes smaller or 0.
