Description
Requests arc density. If the arc average
window (Command 7) is set for 1 second,
this command returns the number of arcs
that occurred in the previous second. If
the arc average window is set for greater
than 1 second, the command returns the
number of arcs per second averaged over
the length of the window. The returning
packet contains 4 data bytes.
• first/second byte (16-bit value) =
micro arcs
• third/fourth bytes (16-bit value) =
hard arcs.
Requests how many micro arcs occurred
in the previous run; returning packet
contains 4 data bytes (32-bit value)
indicating the number of micro arcs in
the previous run.
Note: The unit records a micro arc each
time the output voltage goes below
the voltage arc trip level set with
Command 10. All arc counters are
updated every 100 ms or 10 times
per second.
Requests how many hard arcs occurred in
the previous run; returning packet
contains 4 data bytes (32-bit value)
indicating the number of hard arcs in the
previous run.
Note: The unit records a hard arc every
time the output voltage goes below
the voltage arc trip level for longer
than the arc detect time. The unit
then shuts down for the arc
shutdown time period. All arc
counters are updated every 100 ms
or 10 times per second.
