4-6 Setting the SP Upper- and Lower-Limit Values
4-6-1 Set Point Limiter
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 this set point limiter are set by
the “set point upper limit” and “set point lower limit” parameters in the “initial
setting level”, respectively. However, note that 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 temperature unit are changed, the set point limiter is forcibly reset to
the sensor setting range.
