Power-saving mode (Standby)
You can activate the power-saving mode by either pressing the push-button
> see 4 chapter
for a pro-
longed time or by setting a parameter in the machine configuration menu (time-controlled power-saving
mode
)
> see 5.6 chapter
.
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 ma-
chine is ready for welding again.

Access control
The machine control can be locked to secure it against unauthorised or unintentional adjustment. The ac-
cess block has the following effect:
• The parameters and their settings in the machine configuration menu, Expert menu and operation se-
quence can only be viewed but not changed.
• Welding procedure and welding current polarity cannot be changed.
The parameters for setting the access block are configured in the machine configuration
menu
> see 5.6 chapter
.
Enabling access block
• Assign the access code for the access block: Select parameter
and select a number code (0
–
999).
• Enable access block: Set parameter
to access block enabled
.
The access block activation is indicated by the "Access block active" signal light
> see 4 chapter
.
Disabling access block
• Enter the access code for the access block: Select parameter
and enter the previously selected
number code (0
–999).
• Disable access block: Set parameter
to access block disabled
. The only way to disable the
access block is to enter the selected number code.

Voltage reducing device
Only machine variants with the (VRD/SVRD/AUS/RU) code are equipped with a voltage reduction device
(VRD). The VRD is used for increased safety, especially in hazardous environments such as shipbuilding,
pipe construction or mining.
A VRD is mandatory in some countries and required by many on-site safety instructions for power
sources.
The VRD
> see 4 chapter
signal light is illuminated when the voltage reduction device is operating without
fault and the output voltage is reduced to a value specified in the relevant standard (see technical data).
