Advanced control signal operation
The control signal operation has been improved in comparison to software version 01. The expanded
control signal operation is activated automatically once a specific software version is available in the
power source (see also chapter 13). With TETRIX systems, the BUSINT X11 has a range of further
control voltages in addition to the main current and cold wire.
A new signal has been defined for motor on/off. 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.
NOTE
The "Motor on" function is not available with PHOENIX systems!
The "Motor on" signal takes priority over the signals for inching and reverse inching!
The manual gas control function is controlled in the same way on PHOENIX and TETRIX systems and
permits separate gas pre-flows and post-flows.
A safety function is used to ensure 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 whilst a process is running; if the gas is required to be deactivated, the
gas is shut off automatically when the process is switched off. This corresponds to a gas post-flow
duration of 0.
The control of the cold wire in TETRIX systems means that any function can be carried out in the
process. The responses of the cold wire are as follows:
• If the motor is activated without 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 once "Motor on" has been issued and there is a nominal value in force. 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 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, the
wire is moved forwards again by the advance path (that 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.
