4 Principles of Operation
The BMPC/2 can be operated in two different modes:
•
Manual
mode or,
•
Automatic Pump
mode.
The "Manual Mode" is the standard mode of operation after the unit is turned on or reset.
In manual mode all the pumps and valves can be operated manually.
In
"Automatic Pump Mode" all the pumps and valves are controlled automatically. This is
the preferred mode for the BMPC/2.
4.1 Manual Mode
The operation of the pumps and valves in manual mode takes place with the help of the
different buttons located on the front plate of the BMPC/2 control unit. The function of
these buttons, which are illustrated in the following diagram, will be discussed in the fol-
lowing sections.
