Sensor Voltage; Power-Saving Mode (Standby); Access Control - EWM Tetrix 352 Synergic Operating Instructions Manual

Design and function

Power-saving mode (Standby)

5.6.2

Sensor Voltage

The sensor voltage is transmitted via PIN F of the mechanised welding torch connection socket (X53).
Outside the welding process, there is a voltage of approx. 12 V on the welding torch electrode. If the
electrode comes into contact with the workpiece or the molten pool, the short-circuit produced means that
when using the relevant interface (BUSINT X11/RINT X12), the resultant signal can be used for various
functions (e.g. workpiece search).
The output signal can be used to connect the cold wire component in order to enable fusing detection at
the end of the process.
5.7 Power-saving mode (Standby)
You can activate the power-saving mode by either pressing the push-button > see 4.3 chapter for a
prolonged time or by setting a parameter in the machine configuration menu (time-controlled power-
saving mode
When power-saving mode is activated, the machine displays show the horizontal digit in the
centre of the display only.
Pressing any operating element (e.g. turning a rotary knob) deactivates power-saving mode and the
machine is ready for welding again.

Access control

These accessory components can be retrofitted as an option > see 9 chapter.
To protect against unauthorised or unintentional adjustment of the welding parameters on the machine,
the control input can be locked with the aid of a key switch.
