Operation
LED Indicators : Current Leads Energized
The state of this LED is kept in nonvolatile memory when the
Model 430 is powered off, so that the LED state is retained even
during a power cycle of the Model 430. Thus, the MAGNET IN
PERSISTENT MODE LED is an indicator that the magnet is
persistent and has at least some persistent field.
3.8.2.3 Current Leads Energized Indicator
The blue CURRENT LEADS ENERGIZED LED indicates that at
least 100 mA of current is flowing in the Model 430 power supply
system output current leads.
3.8.2.4 Magnet Quench Indicator
The red MAGNET QUENCH LED indicates that a magnet quench
condition has been detected. See section 3.15 on page 88 for details.
3.8.3 SHIFT Indicator
The green SHIFT LED indicates that the SHIFT key has been pressed, and
the next numeric keypad key pressed will actuate the shifted function
(shown in light blue) rather than the numeric keypad function. See
section 3.7 on page 34 for details of SHIFT key use.
3.9 Setup Menu
Setup of the Model 430 Programmer requires the user to navigate the
setup menu. Navigation of the setup menu is very intuitive — quite
similar, for example, to the use of a cell phone menu.
3.9.1 Entering / Exiting Setup Menu
To enter the setup menu, simply press the MENU key. When in any of the
setup menus, pressing the MENU key will exit the setup menu. The MENU
key toggles the Model 430 Programmer in and out of setup mode.
Alternately, if the top level setup menu is being displayed, pressing the
ESC key exits the setup menu.
3.9.2 Menu Navigation
Pressing the MENU key enters the menu structure at the top level. The
display will look approximately as shown below:
+0.00 A - Setup Mode (Select one)
+0.50 Vs Supply Load Misc
