6. Check the correction value for maximum powder output C1 on the
(6) display, and set it to 100 (%) if necessary
For the next steps a measuring bag is necessary, for weighing
the powder output.
– Do not forget to note the dead weight of the measuring bag.
7. Put the measuring bag over the gun nozzle and fasten it.
8. Press the gun key (2) to switch on the gun for 60 seconds
9. After this time has elapsed, switch off the gun, remove the
measuring bag and weigh it. The powder output should be between
10-15 gr
10. If no powder is expelled from the gun, increase the minimum powder
output value C0 (range 0.5-3.0 Nm³/h)
11. If too much powder is expelled from the gun, decrease the minimum
powder output value C0 (range 0.5-3.0 Nm³/h)
12. Repeat steps 7 and 8, until the powder output amounts to 10-15 g.
Annotate the adjusted minimum powder output value C0 in the table
Powder hose correction
– procedure
1. Set the powder output value to 80 (%) on the (6) 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)
