7-5-4 SP Upper Limit (sl-h)
SP Lower Limit (sl-l)
Function • These parameters set the upper and lower limits for the SP setting. The
SP can be set within the range defined by the upper and lower limit set
values in the “SP upper limit” and “SP lower limit” parameters. If existing
SP settings are out of the range, they will be changed to either the upper
or lower limits (which-ever is closest).
• When the temperature input type and temperature unit are changed, the
SP upper limit and SP lower limit will be changed to the upper and lower
limits of the sensor.
• During temperature input, the decimal point position is dependent on the
currently selected sensor. During analog input, it is dependent on the
“decimal point” parameter setting.
