5-5 Setting the SP Upper and Lower Limit
Values
The setting range of the set point is limited by the set point limiter. This function can be used to prevent
setting incorrect set points. The upper- and lower-limit values of the set point limiter are set using the
Set Point Upper Limit and Set Point Lower Limit parameters in the Initial Setting Level. If the set point is
not within the range set for the set point limiter as the result of changes to the Set Point Upper Limit or
Set Point Lower Limit parameter, the set point will automatically be changed to a value within the set
range. When the set point limiter is reset, the set point is forcibly changed to the upper- or lower-limit
value of the set point limiter if the set point is out of the limiter range. Also, when the input type and the
temperature unit, scaling upper-limit value, or lower-limit value are changed, the set point limiter is forc-
ibly reset to the input setting range or the scaling upper- or lower-limit value.
