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)
1. Control cable plug 4. Connection to FLC-2 or KSC-2
(by-passing the switch)
2. EURO central connector 5. Power source / robot control for nozzle
sense function
3. Control cable
5.8.3 Hollow wrist system with Helix cable assembly
5.8.3.1 Connecting the safety-off mechanism KSC-2
The switch for the safety-off functionality KSC-2 is connected through the control cable, see
(2) 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
