hard arc
count limit
Sets the number of hard arcs required for the
power supply to provide an arc indication. (If
the limit is reached during a process cycle, then
after output shuts off, the ARC LED on the
passive panel or active control panel lights and,
if applicable, a pulse is sent to the User port
ARC.D output signal. For more information,
see “I/O Communication and Control” on
page -1 .
Send 4 data bytes (a 32-bit value) indicating
the number of arcs; the value must be at least 0
but no greater than the maximum set for your
unit.
Note: If you set the hard arc count limit to 0,
each time a hard arc occurs the ARC
LED lights for a predetermined time
and, if applicable, a signal is sent to the
User port.
Read back this value with command 178.
