and the Pinnacle Remote Panel provide access to all operating parameters and control
functions. The User port provides limited access to operating parameters and control
functions.
Microprocessor Advantages
The internal microprocessor checks for proper circuit operation while supervising all
operating parameters. System diagnostics run when the unit is initially powered up.
The most recent power settings and conditions (such as producing output) are retained
in non-volatile memory.
Displays
The displays on the passive panels as well as the control panels show power, current,
or voltage levels. (The displays show levels for unit A and unit B if this is a dual unit.)
They also display information about output, pulsing, set point, interlock, bus fault,
overtemp, arcs, and error codes.
Arc-suppression Feature
The Pinnacle Plus+ supply's arc-handling feature ensures the shortest arc recovery
time in the industry. You can implement user-defined arc-handling functions during
your normal process cycle. Parameters, including hard arc count limit, voltage trip
level, enable, and disable, are selectable through the unit’s active control panel
(optional), Pinnacle Remote Active Panel, or a serial (Host) communications port.
THEORY OF OPERATION
The Pinnacle Plus+ power supply is a sophisticated and intelligent DC pulse power
supply designed exclusively for use in vacuum environments. Figure 2-1 on page 2-2
and the following paragraphs outline the theory of operation.
