New VAC position
With the release of the software version 3.05 on 29.03.2018 the ignition behaviour of some welding char-
acteristics has been improved. As a result, the magnetic field of the welding inductor also increases. This
stronger magnetic field also affected the current sensor VAC, which was mounted relatively close to the
welding choke, and sporadically there were false measurings. In these cases, the power source responded
with error messages E16 or E24 (overcurrent).
Since 17.09.2018, the VAC is mounted with a retaining plate (602.1437.0) in a new position to ensure a
greater distance to the inductor.
While the current sensor was in the positive line with the previous wiring, it is now in the minus line. When
retrofitting, the correct current direction of the VAC must be ensured.
