5.10.4 The return time TZ-RESET
Most positioning equipment uses the I>0 signal to optimise the cycle time to trigger the positioning
equipment after the process. This often makes it more difficult to reliably detect sticking. An adjustable
time TZ-RESET can be used to set the period after which the I>0 signal is reset after the process is shut
down.
NOTE
If both TZ-SET and TZ-RESET are set to the value 0, the original process signal I>0 is
permitted through to the higher level control unfiltered. This can be desirable if the
control has its own process signal monitoring
Parameters TZ-SET and TZ-RESET are currently only available for PHOENIX systems. In
TETRIX systems, these values are specified as follows:
• TZ-SET = 30 ms
• TZ-RESET = 30 ms
5.11 Fusing
detection
Reliable fusion detection of the welding wire is especially important in automated processes to protect the
workpiece and positioning device, including the welding equipment, against damage.
For this reason the BUSINTX11 has intelligent fusion detection which uses the sensor voltage from the
PHOENIX for wire fusion detection.
The fusion detection is carried out automatically for a narrow time window at the end of the process,
approx. 200ms after extinguishing the arc. The detection duration depends on the setting of the gas post-
flow duration, but is a maximum of 1s.
If fusion is detected, the signal is displayed until the system is re-started.
If the wire is cut off from the workpiece before the next start, the signal is withdrawn permanently.
The use of the fusion function for TETRIX systems is only possible following retrofitting/fitting
with a sensor voltage and the relevant equipment on the torch being used.
5.12 Position
search
The position search function can only be used in combination with the “Actual fast external values” option
and is activated via jumper JP2:
JP 2
Function
-
Actual values via system bus (factory setting)
X
Actual values are expected via plug X7, position search enabled
X – Jumper plugged in
Ideally the BUSINTX11 in the “External extension housing” variant should be fitted on the power source
for this purpose; this will ensure the simple and safe transmission of the actual values to the module
(short paths without interference). When using the switching cabinet variant, a shielded cable should
always be used to connect the actual values.
The function can only be activated via the relevant release signals when the system is at a standstill (no
welding operation).
On workpiece contact, a fast detection and forwarding of the status to the field bus is carried out via the “
I>0” signal.
