7.1

Special features

The welding controller features the following specifics:
• The timer has been prepared for networking with an Interbus-PMS module or a
Profibus-FMS module or an Ethernet module.
• The Control works with 256 welding programs („0"..."255"), with up to 256
welding spots and with 16 Electrodes (0..15). The electrode „0" is an single
electrode, should not be used, because electrode "0" cannot be reset. The
electrode „0" will not be interpreted as not active electrode.
• The „Stop circuit open / no 24 V" fault is automatically reset.
• The DC link voltage is always verified, the fault message is automatically reset.
7.1.1

KSR selection:

Each electrode can be assigned to one of three welding circuits. Default value is
the KSR selection 1
7.1.2

Initial dressing function:

Initial dressing function will be reported as actual message (selected program).
7.1.3

Outputs for tip dress request

With tip dress request (tip dress prewarning) the corresponding electrode number
will be shown via 4 bit.
7.1.4

Electrode specific tip dress and tip change acknowledges

The acknowledge inputs for tip dress and tip change are for each electrode. For
change the corresponding electrode number has to be selected.
7.1.5 Discrete input „Prop.-Valve active"
If this input get 24V, then the selected spot (program) assigned pressure value
will be written at the prop. valve and at the serial pressure outputs.
If this input get 0V, then the analog and serial pressure outputs are set to "0".
If this input get to 0V during a process, then the process will be stopped and a
welding process fault will be reported.
7.1.6 Serial output „Counter status 0 for at least one electrode"
If at least one electrode has the counter status „0", then this output will be set,
otherwise the output will be reset. Used electrodes are all electrodes (excepted
0), which are assigned to a welding program.
