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 temperature unit are
changed, the set point limiter is forcibly reset to the sensor setting range.

Set point lower limit: Initial setting level
Set the set point upper and lower limits in the "set point upper limit" and "set
point lower limit" parameters in the initial setting level. In this example, it is
assumed that the input type is set to a K thermocouple with a temperature
range of 200 to 1300 C.
