Control Actions
An Action Clause of a Control Rule can have one of the following formats:
PUMP id STATUS = ON/OFF
CONDUIT id STATUS = OPEN/CLOSED
PUMP/ORIFICE/WEIR/OUTLET id SETTING = value
The meaning of SETTING depends on the object being controlled:
- for Pumps it is a multiplier applied to the flow computed from the pump curve (or relative pump speed for a TYPE5 pump).
- for Orifices it is the fractional amount that the orifice is fully open (orifice control is accomplished by lowering or raising a horizontal gate from the top of the orifice).
- for Weirs it is the fractional amount of the original freeboard that exists (i.e., weir control is accomplished by moving the crest height up or down)
- for Outlets it is a multiplier applied to the flow computed from the outlet's rating curve.
Some examples of action clauses are:
PUMP P67 STATUS = OFF
ORIFICE O212 SETTING = 0.5
