such as low liquid levels, cryocooler compressor faults, or
abnormal temperatures can be used to trigger a controlled
magnet rampdown, even if the magnet is in persistent mode. See
page 200.
The external rampdown function may be enabled or disabled
according to the preference of the user. The default value is NO.
With the exception of enable control, the settings and parameters
for the external rampdown function can be edited
only
via the
remote interface (see page 173).
A user input for initiating an
external rampdown
is provided on
the rear panel of the Model 430 Programmer
42
. For further
discussion of the quench detection logic and operation, please
refer to on page 125.

This picklist value controls display brightness. As shown above,
there are four brightness settings from which to choose (25%,
50%, 75% and 100%). The default setting is 100%.

The ramp segments value specifies the number of current ranges
which can be given unique ramp rate values. The default value is
1 unless preset by AMI to match a specific superconducting
magnet.
When this value is 1, there is only one ramp rate for the Model
430 Programmer, used for the full available current range. For
multiple ramp rates, set the value to the number of ramp
segments desired (up to ten segments). See page 63 for details
regarding the use of ramp rate segments.
