Setpoint Upper Limit Type: Controller Parameter
The maximum limit allowed for operator setpoint adjustments. It should be set to keep the
setpoint below a value that might cause damage to the process. The adjustment range is
between Scale Range Upper Limit and Scale Range Lower Limit. The value cannot be
moved below the current value of the setpoint.
Display code =
-)1' , default value is Scale Range Upper Limit.
Also refer to Scale Range Lower Limit, Scale Range Upper Limit, Setpoint and Setpoint
Lower Limit.
Setpoint Lower Limit Type: Controller Parameter
The minimum limit allowed for operator setpoint adjustments. It should be set to keep the
setpoint above a value that might cause damage to the process. The adjustment range is
between Scale Range Lowe Limit and Scale Range Upper Limit. The value cannot be moved
above the current value of the setpoint.
Display code =
-)'' , default value = Scale Range Lower Limit.
Also refer to Scale Range Lower Limit, Scale Range Upper Limit, Setpoint and Setpoint
Upper Limit.
Setpoint Ramping Enable Type: Controller Parameter
Enables or disables the viewing and adjustment of the Setpoint Ramp Rate in Operator
Mode. This parameter does not disable the ramping SP feature; it merely removes it from
Operator Mode. It can still be viewed and adjusted in Setup Mode. To turn off ramping, the
ramp rate must be set to OFF (blank).
Display code =
-)+ , default setting = Disabled.
Also refer to Process Variable, Setpoint and Setpoint Ramp Rate.
Setpoint Ramp Rate Type: Controller Parameter
The rate at which the actual setpoint value will move towards its target value, when the
setpoint value is adjusted or the active setpoint is changed. With ramping in use, the initial
value of the actual setpoint at power up, or when switching back to automatic mode from
manual control, will be equal to the current process variable value. The actual setpoint will
rise/fall at the ramp rate set, until it reaches the target setpoint value. Setpoint ramping is
used to protect the process from sudden changes in the setpoint, which would result in a
rapid rise in the process variable.
Display code =
+) , default setting = OFF (blank).
