5702269-C Operation 6-5
Pinnacle™ Plus+ 10 kW
High Power Operation
For high power operation the power limit is set to greater than 1000 W, and the
following is true:
Mode Low Power Operation
Ignition
No ignition is present in all control modes. The Pinnacle Plus+
unit begins pulsing immediately.
Hard and
Micro Arc
Shutdown
Following the shutdown the unit continues to pulse regardless
of plasma conditions.
Open
Load/Circuit
The unit continues to pulse.
Mode High Power Operation
Ignition
Under high power operation (Power or Current regulation),
pulsing is disabled, the voltage jumps to maximum voltage
(~1350 V) and is held until the current is detected flowing
above 2.0 A. At this time pulsing is started.
Should 100 ms expire before pulsing begins, a duty cycle is
imposed on the unit’s voltage limit to prevent the unit from
being damaged. This duty cycle is 100 ms at maximum
voltage and 900 ms at the user voltage limit. This cycle will
repeat until the current is detected flowing above 2.0 A at
which time pulsing is started.
Note: If the regulation mode is Voltage, the output on voltage
will jump to a maximum of the set point plus 12.5%
and no duty is imposed.
Hard Arc
Shutdown
Following the shutdown should the unit detect the current has
dropped below 2.0 A (which is a good indication the plasma
has extinguished), the unit will return to ignition state,
otherwise the unit continues to pulse.
Open
Load/Circuit
Should the unit detect an open circuit condition, the unit will
return to ignition state, otherwise, the unit continues to pulse.
