7. If no powder is expelled from the gun, return to the system
parameter mode and increase the minimum powder output
value C0 (range 0.5-3.0 dm³/h)
8. Repeat steps 5 and 6, until the powder output amounts to 10-
15 g. Annotate the adjusted minimum powder output value
C0 in the table
Exit the system parameter mode by pressing the key T16.
Procedure (powder hose correction)
1. Set the powder output value to 80 (%) on the A1 display
2. Put the measuring bag over the gun nozzle and fasten it. Switch
on the gun for 60 seconds
3. Switch off the gun after 60 seconds, remove the measuring bag
and weigh it
4. Annotate the powder output in g/min in the table
Calculate the powder output correction according to following formula:
C1 (%) =
smallest powder output
x 100
measured powder output
5. Annotate the calculated values (C1) for each individual gun in the
table and enter the values to the control unit (therefore, repeat
the steps 2 and 3)
