Primary Output Power Limit Type: Controller Parameter
Used to limit the power level of the Primary Output and may be used to protect the process
being controlled. It may be adjusted between 0% and 100%. This parameter is not
applicable if the primary output is set for On-Off control.
Display code is

, default value = 100%
Also refer to On-Off Control.
Primary Proportional Band Type: Controller Tuning Parameter
The portion of the input span over which the Primary Output power level is proportional to the
process variable value. It may be adjusted in the range 0.0% (ON/OFF) to 999.9%.
Applicable if Control Type is Single or Dual. For dual control a Secondary Proportional band
is used for the second output. The Control Action can be Direct or Reverse acting.
The Display value =

, default value = 5.0%.
Also refer to Control Action, Control Type, On-Off Control, Input Span, Overlap/Deadband,
PID, Secondary Proportional Band, and Tuning.
Process High Alarm 1 Value Type: General Parameter
This parameter, applicable only when Alarm 1 is selected to be a Process High alarm,
defines the process variable value above which Alarm 1 will be active. Its value may be
adjusted between Scale Range Upper Limit and Scale Range Lower Limit.
Display code =

, Default value = Scale Range Upper Limit.
Also refer to Alarm Operation, Process High Alarm 2 Value, Process Variable, Scale Range
Lower Limit and Scale Range Upper Limit.
Process High Alarm 2 Value Type: General Parameter
This parameter, applicable only when Alarm 2 is selected to be a Process High alarm. It is
similar to the Process High Alarm 1 Value.
Display code =

, Default value = Scale Range Upper Limit.
Also refer to Alarm Operation, Process High Alarm 1 Value, Process Variable, Scale Range
Lower Limit and Scale Range Upper Limit.
Process Low Alarm 1 Value Type: General Parameter
This parameter, applicable only when Alarm 1 is selected to be a Process low alarm, defines
the process variable value below which Alarm 1 will be active. Its value may be adjusted
between Scale Range Upper Limit and Scale Range Lower Limit.
Display code =

, Default value = Scale Range Lower Limit.
Also refer to Alarm Operation, Process Low Alarm 2 Value, Process Variable, Scale Range
Lower Limit and Scale Range Upper Limit.
Process Low Alarm 2 Value Type: General Parameter
This parameter, applicable only when Alarm 2 is selected to be a Process low alarm. It is
similar to the Process Low Alarm 1 Value.
Display code =

, default value = Scale Range Lower Limit.
Also refer to Alarm Operation, Process Low Alarm 1 Value, Process Variable, Scale Range
Lower Limit and Scale Range Upper Limit.
