Principles of Operation
Refer to the section "Monitor & Alarm Mode" on page 33 for more information on the
BMPC/2 software.
4.3 Automatic Pump Mode
In automatic pump mode all the pumps and valves are controlled automatically. It is not
possible to operate a pump or valve manually using the front panel buttons when the
system is in automatic mode.
To change to automatic pump mode when you are in manual mode press the AUTO but-
ton. The green lamp indicates when the unit is in automatic pump mode.

CAUTION
Never use Pump 1 when Valve 2 is open, or Pump 2 when Valve 1 is
open
This can result in a return flow of air into the pump line and an increase in the magnet
temperature.

When using Pump 1, first close Valve 2.

When using Pump 2, first close Valve 1.
NOTICE
In manual mode the BMPC/2 will not react to critical magnet parameters
When, for example, the helium flow is too low the Pump 2 will not automatically
switch on. However, when the BMPC/2 software is operating in Monitor & Alarm
mode, you will nevertheless be alarmed when important magnet parameters exceed
or fall below their limit values.

Always place the BMPC/2 software in Monitor & Alarm mode when working in
manual mode.
