5.8.1.2 Connecting the nozzle sense function
If the robot control provides a control circuit for nozzle sense functionality, this can be applied
for both KS-2 and FL-1. The connection is accomplished with a 1-wire connection, see (8) in
the previous illustration.
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)
5.8.2 Hollow wrist system with Infiniturn cable assembly
5.8.2.1 Connecting the safety-off mechanism KSC-2
The switch for the safety-off functionality KSC-2 is connected through the control cable, see
(3) in the illustration below. This connects to the KSC-2 unit via the control cable plug (1).
The safety-off signal requires a 2-wire connection (black/black) to the safety-off circuit in the
robot control (5).
If a collision is detected, the control circuit (normally closed) will be interrupted (4).
Rating of the control circuit: max. 48 V / 1 A.

5.8.2.2 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 2-wire connection (black/black) to the nozzle sense
circuit in the robot control (5), see illustration below.
