MASTER/SLAVE INPUT ON/OFF COMBINATIONS
Unique logic in the Pinnacle Plus+ power supply lets you power on and off master and
slave units independently of one another. During on and off sequences, the master unit
"re-scales" the total output; that is, its I/O signals adjust to accommodate the most
recent change in output capability of the combined units.
SYNC PULSE OPERATION
Note: This function is only available on units specially configured for Sync Pulse
operation at the factory.
A unique feature of the Pinnacle Plus+ power supply is that up to six units can be
synchronized to operate at the same frequency with independent set points and On/Off
control. This Sync Pulse feature is very useful for reducing arcing in multiple cathode
applications. Additionally, Sync Pulse features a broadcast mode in which hard arc
detection signals are transmitted to other units. The units receiving the hard arc signal
will control its output in sync with all other units receiving the signal.
Note: The Sync Pulse feature may be available even if your unit is not configured with
a master/slave Host card.
The broadcast hard arc detection feature can be disabled from the Active Front Panel,
or from a Remote Active Front Panel by using the Process menu.
