Table 6 - Pump Profiles for Alternating
The following outlet programs are needed:
Streams_Timer <Virtual Outlet>
OSC 010:00/010:00/000:00 Then ON
Lights <real outlet with lights>
… Program to run lights (not important to this example)
Streams_L <Real variable speed port where the Left Streams pump is
connected>
Set L_Streams
If Outlet Lights = OFF Then Night
If Outlet Streams_Timer = ON Then OFF
If FeedA 000 Then OFF
Streams_R <Real variable speed port where the Right Streams pump is
connected>
Set R_Streams
If Outlet Lights = OFF Then Night
If Outlet Streams_Timer = OFF Then OFF
If FeedA 000 Then OFF
The Streams_Timer virtual outlet is used to create the timing for switching
pumps. Modify the OSC command to set how frequently the active pump should
alternate between the left and right pump. The Lights outlet is shown for
illustrative purposes only, its program is not important to this example. The
program on each Streams pump starts by setting the left or right Profile. This
Profile is overridden by the Night Profile when outlet Lights is OFF (night). The
next statement turns either the left or the right streams OFF based on the state
of the Streams_Timer (the different program statements allow only the left or
right pump to remain on at one time). The final command turns both pumps off
when Feed Timer A is active.
