Software Highlights; Arc Suppression; Fault Conditions And Indicators - Advanced Energy MDX II User Manual

Output Measurement
The output measurement section measures current and voltage and calculates power. These
signals are typically scaled to 0 to 10 Vdc and sent to the logic, control, and remote interfaces.
Logic Control
The microprocessor in the logic control section uses operator-supplied parameters and
setpoints to control the output. This section also provides status information to the operator
through all interfaces and controls the input section.
Control Panel Display
The display on the control panel communicates operator-supplied inputs to the logic control
section and provides the operator with status information.
Remote Interfaces
Both remote interfaces communicate operator-supplied inputs to the logic control section from
the serial port (RS-232 or RS-485) and the User port (analog and digital) and provide the
operator with status information.

SOFTWARE HIGHLIGHTS

The MDXII unit provides many standard software functions, some of which are highlighted
here. For more information about optional software features, refer to "Understanding the
Optional Software Features" on page 2-19

Arc Suppression

The arc-handling software provides multi-level suppression and quenching of different types
of arcs, which reduces target burn-in time and material loss. When the software senses a drop
in impedance, it turn offs the power immediately. The software then controls start-up so that
hot spots cool before power is reapplied.
Refer to "Arc Controls" on page 5-5 for information about the options available for handling
arcs.

Fault Conditions and Indicators

Several fault conditions will either cause the MDXII unit to turn off output or will prevent you
from turning on output. These conditions include open interlock loops, input power failure,
over-temperature, and so on.
When a fault condition occurs, a fault message appears on the two-line display of the control
panel. Some fault conditions cause an LED to light on a passive front panel (if your MDXII
unit has a passive front panel).
Refer to "Panel LEDs and Fault Messages" on page 8-4 for descriptions of LED and fault
message indicators and suggested actions to take.
