ControlDraw Distillation SBC
This web was generated automatically from a sample ControlDraw model.
Move the mouse over the diagram area - you can click on the objects that have numbers by them to go to the detailed diagram for the object. It is a bit like using ControlDraw (but that is much more powerful!)

12 - Dual Pump (Control Module)

Consider a simple Equipment Module consisting of two motor controls for two pumps
(A & B) and two discrete isolation valves for each pump (A_IN, A_OUT, B_IN,
B_OUT) for a total of six Control Modules.
This Equipment Module might have seven defined Modes of Operation:
1. A Running B Standby
2. A Running B Out of Service
3. B Running A Standby
4. B Running A Out of Service
5. A & B Out of Service
6. A & B Standby
7. A & B Running
