1
Collective interference signal light
For error messages, see the "Rectifying faults" chapter
2
Excess temperature signal light
In case of excess temperature, temperature monitors de-activate the power unit, and
the excess temperature control lamp comes on. Once the machine has cooled down,
welding can continue without any further measures.
3
VRD
Voltage reduction device (VRD)
The VRD 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). The voltage reduction device is only active on VRD
machine versions.
