Advanced control signal operation

Control signal operation has been improved in comparison to RINT X11. Advanced control signal
operation is activated automatically once a specific software version is available in the power source. In
addition to main current and cold wire, the RINT X12 also has 3 more control voltages for parameterising
pulse modes.
A new signal has been defined for the motor on/off function. For the inching function, this means that
there is a signal (independent of the inching signal), which can be used to realise separate inching
functions together with the control signal specification for the cold wire.
The "motor on" function is not available with Phoenix / alpha Q systems!
The "motor on" signal overrides the signals for inching and reverse inching!
The manual gas control function is controlled in the same way on Phoenix / alpha Q and Tetrix / forceTig
systems and permits separate gas pre-flows and post-flows.
A safety function ensures the following aspects with regard to the gas:
•
If no gas has been activated at the beginning of the process, it is switched on automatically
•
The gas cannot be deactivated while a process is running; if this is necessary, the gas is shut off
automatically when the process is switched off. This corresponds to a gas post-flow duration of 0.
Cold wire in control in Tetrix / forceTig systems enables any function to be carried out in the process. The
cold wire behaves in the following ways:
•
If the motor is activated without a nominal value (motor on), the motor is not started; if the process is
then ended, this does not result in any motor action
•
The motor starts as soon as "motor on" has been issued and there is a nominal value present. If the
motor signal is removed in the process, the wire is retracted immediately with the retraction that can
be set on the PC300.NET.
•
If the nominal value is set to 0 in the process with the motor activated, the motor will remain stationary
without retraction. Another nominal value then restarts the motor.
•
If the wire in the process has been triggered to retract due to the control signal being removed and if
the end of the process then follows, the wire is moved forwards again by the advance path (which can
also be set as required) after the adjustable delay time elapses. This means that the wire is then in the
optimum position once again.
