example of the data to be entered and how it is entered is described in
section 3.11 on page 72.
If the Model 430 Programmer was purchased as part of a magnet system,
essential data will have already been entered at the AMI factory and a
configuration sheet will have been provided detailing the settings.
2.5 System Interconnects
If the Model 430 Programmer was purchased as part of a magnet system,
all applicable system components and wiring harnesses will have been
shipped with the system.
The diagrams that follow will assist in system equipment setup.
Caution
The wiring between the power supply and the magnet current leads
must be of sufficient size to carry the full rated current of the power
supply. Typically, for short runs (less than 25 ft, or 7.6 m), 2 AWG
wire is sufficient for 125 A current, and 2/0 AWG wire is best for
250 A current.
Note that an AMI Model 13x Liquid Helium Level Instrument is shown as
a possible component of each integrated system. The main
instrumentation cable connecting the magnet support stand to one of the
Model 430 Programmer MAGNET STATION connectors contains all the
instrumentation and control connections needed to control and monitor
the magnet. The signals in this cable which are required to monitor LHe
level and temperatures are also presented at the LHe Level / Temp
Connectors. Refer to the Appendix for pin-outs of these and other
connectors.
