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 their minimum value
