Number of Multi-SP Uses: Initial setting level
The setting range of the set point is limited by the set point limiter. The set
point limiter is used to prevent the control target from reaching abnormal tem-
peratures. 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. 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 forcibly reset to the input setting range or the scaling upper- or lower-limit
value.
