Parameter Functions & Definitions
Set Point Upper-Limit,
Set Point Lower-Limit
Function:
These parameters allow you to configure the maximum allowable
range for an operator to enter the set point value. The SP can be configured
within the range defined by the Upper- and Lower-Limit values in the Set
Point Upper-Limit and Set Point Lower-Limit parameters. If an attempt is
made to enter a SP value outside the upper or Lower-Limit from the keypad
the set point display will flash at the configured maximum upper- or
Lower-Limit value.
If the temperature Input Type or temperature units are changed, the set point
Upper-Limit and set point Lower-Limit are forcibly changed by the controller
to the default Upper- and Lower-Limits of the newly configured sensor.
For a temperature input, the decimal point position is dependent on the
currently selected sensor. For an analog input, it is dependent on the Decimal
Point parameter setting.
