If nominal set point value is too low or too high compared to nominal voltage level, the control
will display one of the following errors:

To clear these errors, simply press any push button. If either of these two errors occur during
C.C.C.C.
C.C.C.C.
C.C. programming, the control will not enable AVC; i.e.,
C.C.C.C.
C.C.C.C.
C.C. will remain zero.
If AVC is enabled, the control monitors relative line voltage changes from the nominal set
point. If the control detects line voltage changes, it will average these values. When the control
is initiated to weld, it compares nominal relative voltage and measured average values to make
a correction in the firing angle used for the weld; i.e., to compensate for any line voltage changes.

C.C. values of

31, the threshold values determine a window within which error messages
are not triggered. These values are valid for any voltage level from 110 VAC to 575 VAC, since
the control uses nominal set point. Any time when
C.C.C.C.
C.C.C.C.
C.C. is reprogrammed, nominal voltage set
point will be reset.
If the line voltage surpasses the threshold, the control will display an error announcing that the
line voltage threshold has been exceeded. If measured average voltage is lower than low window
(nominal set points minus threshold), or higher than high window (nominal set points plus
threshold), the control will display one of the following errors:
