Code Description Criteria Remedy
H08
Conveying air volume too
high (setting of powder
share on the display)
The preset value for conveying
air is too high compared to the
supplementary air setting Lower conveying air value
or increase value for
supplementary air to
equalize air volumes to the
injector, delete error code
H09
Powder output higher
than 100%
The powder output multiplied by
the powder hose length factor
and daily correction value is
greater than 100%
Daily correction value too large Reduce powder output
Reduce daily correction
value
H10
Conveying air range
lower deviation
The theoretical value for
conveying air falls below
minimum
Total air is smaller than minimum Limit conveying air to its
minimum value
