Advanced Energy
The next several pages contain step-by-step instructions on how to access and perform
operational functions from the MDXII control panel menu. These instructions are organized
by the first-level menu functions illustrated in Figure 6-2 on page 6-4.

Using Limits Functions

CURRENT
⇒
LIMITS
POWER
Use LIMITS to limit the maximum power and current output. The current limit is especially
useful for limiting current into an arc. When you set a limit, you are effectively preventing
your supply's full rated output from being delivered into a low impedance.

Using Timers Functions

Note: When you use the TIMERS menu to program a recipe and have set the program source
to internal, the "Timers Active" message replaces the display line on the control panel.

PROGRAMMING RAMP TIME

See "Ramp Timer" on page 5-2 for a description of this function. Follow these steps:
⇒
TIMERS RAMP/RUN
1. At the top-level menu, press the TIMERS soft key.
2. Press the RAMP/RUN soft key.
3. Turn the MODIFY knob to select a value from 1 through 5.
a. If you select only one value, press the ENTER soft key to return to the output display
screen automatically.
b. If you select more than one value, press the ENTER soft key to display RAMP 2
TIMER and so on until you have set all values or scrolled past them with the ENTER
soft key.
Note: You can disable the entire recipe by setting the number of steps to zero.
4. Press either the M (minutes) or S (seconds) soft key
If fast ramp/run is active, and the value for both minutes and seconds is zero, "MS"
displays, allowing you to enter a value in milliseconds. Conversely, if you have entered a
non-zero value for either minutes or seconds, "MS" does not display and you cannot
enter a value for milliseconds.
5. Set the RAMP 1 time by turning the MODIFY knob. Press either of the other soft keys if
you want to set another value.
6. Press the ENTER soft key.
7. Either set the SETPOINT 1 value or press the ENTER soft key (see "Output Setpoint
Level" on page 5-3).
