3.10.3.4 Field Units
This picklist value specifies whether the field is specified and
displayed in units of kilogauss (kG) or tesla (T). The units selected
also applies to remote interface commands. The default setting is
kilogauss.
3.10.3.5 Quench Rate
This picklist value specifies the sensitivity of the quench detection
algorithm. The default value (1.5) will be appropriate for most
magnets. Occasionally, some magnets quench very slowly and the
value of this parameter may need to be adjusted to a lower value so
that the Model 430 Programmer detects the slow quench. The
available range for this parameter is 0.1 to 2.0. The value can be set
by using either the numeric keypad per section 3.3 on page 29 or
the fine adjust knob (section 3.4 on page 31). If the magnet
quenches and the Model 430 Programmer does not select the
quench, the value should be lowered until all quenches are
detected.
3.10.3.6 Settings Protection
Settings Protection allows virtually
1
every command and menu/
submenu setting to be protected from alteration or use. If a setting
is locked, it cannot be used from the front panel without first
unlocking the setting, which requires entering the correct
password. Note that settings protection only applies to front panel
access, and not to remote access (via Ethernet or RS-232).
The use of settings protection allows specific commands and/or
settings to be locked by a magnet system “administrator,” so that
1. The one exception is the
RAMP TO ZERO
button which cannot be locked. Also,
Magnet Inductance and Net Settings are not subject to locking due to their “read-
only” nature.
