As a precursor to operating a superconducting magnet with the Model
430 Programmer and power supply, all of the setup items should be
reviewed and set if necessary with appropriate values for the connected
superconducting magnet.
The figure at left shows an exam-
ple magnet specifications sheet.
Several parameters needed to
operate the magnet are specified.
These values should be entered
into the appropriate setup menu of
the Model 430 Programmer. For
the purposes of this example, the
AMI Model 4Q06125PS power
supply will be assumed, since
rated current for the example mag-
net is 85.6 A.
The Current Limit accessible in the
Protection submenu should be set
to the rated current to prevent
accidental operation of the magnet
above rated field/current. The
magnet specification sheet also
indicates whether a persistent
switch is installed and provides the
recommended heating current. The
persistent switch information is
entered in the Switch submenu.
If your magnet, Model 430
Programmer, and power supply
were purchased as a system from
AMI, the setup menus are preset
by AMI to match the magnet
purchased.
