The initial time/WQ simulation status of a pump is entered/edited in the Pump table, which is accessed by selecting Simulation Data > Simulation Data in Model Tables > Initial Status (Pump).
The initial status for pumps is data associated with each pump in the system. The above sub-menu option therefore gives access to the regular Pump table, where other system data, such as the characteristic curve and relative speed of the pumps, can and should have been entered already.
When entering the Pump table (as described above), the table automatically scrolls to the “Tsim Initial Speed” column. This column needs to be populated by the user, by specifying either 0 = OFF, 1= ON, or a relative speed setting for every pump in the system.
A pump’s status and relative speed can be made to vary throughout a time simulation by the use of control statements, or by specifying a time pattern of relative pump speeds in the Schedule Pattern No column of the Pump table.
(The initial status of a pump is considered system-specific time/WQ simulation data, which is saved as part of the system data. It is not saved as part of the time/WQ simulation-specific data.
The initial status of a pump is a property associated with each pump in the system data. Therefore, it can also be entered/edited directly in the Pump table, or in the Link Info box (also referred to as the Database box) available in the Albion environment, or by the selective editing features available in the Albion environment.
