Description
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 lights and, if
applicable, a pulse is sent to the User port
output signal.) 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 for your unit.
Note: A 0 value disables the hard arc
count limit feature so that the ARC
LED does not light and no signal is
sent to the User port.
Read back this value with Command 178.
Specifies the voltage level at which the
unit indicates an arc is occurring. Send 2
data bytes (16-bit value); the value must
be at least 25 V but no greater than the
maximum for your unit.
Read back this value with Command 171.
Specifies which target will be active.
Send 1 data byte (8-bit value); the value
must be at least 1 but no greater than 8.
Read back this value with Command 156.
Note: The User port has priority for
target selection. Thus to select
targets from the active front panel
or from the Pinnacle Remote Panel
(that is, when the Pinnacle unit is
in local or host control mode), you
must set the target to 1 at the User
port. Leaving the target bits open
or leaving the User port pins
unconnected causes the target
selection at the User port to default
to 1.
