5.8.3.2 Connecting the nozzle sense function
If the robot control provides a control circuit for nozzle sense functionality, this function can
be implemented for both KSC-2 and FLC-2.
The connection is accomplished with a 1-wire connection (green) to the nozzle sense circuit
in the robot control (5), see illustration below.
Usually, the control cable will be directly connected to the wire feeder. See the
manufacturer's documentation for details. The link to the robot control is then implemented
via the power source robot interface.
Rating of the control circuit: max. 50 V / 5 A.
DANGER!
If the nozzle sense function is not being used, the open end of the control cable
on the power source connection side must be properly isolated in order to avoid
short circuits. During certain problems on the torch head, the full welding potential
may be present on this cable.
CAUTION!
After detection of contact (gas nozzle on work piece), quickly reduce or cut off the
maximum current in the nozzle sense circuit in order to avoid overloading of the
system.
(Allowed load max. 1 minute at the rated nominal current)
