5. Description of spray gun and control module
The function of the manual spray gun is to spray powder electrically charged by a high-voltage unit built
into the spray gun that delivers up to 80 kV and 110
µ
A.
Only pressure on the trigger enables start-up of the power supply and electrical charging of the powder.
5.1. Functions available from spray gun
Area 1
: The red
LED under each icon corresponds to the selected voltage/current characteristic in
progress. Selection of a different characteristic is only possible if the trigger is released.
Simultaneous flashing of all LEDs indicates a communication fault with the control module (
Area 2
: Powder flow rate can be adjusted here.
• It can be reduced by pressing the button
• or increased by pressing the button
There are thirteen powder flow rate setting levels, one of which is zero. The operator can display the
powder flow rate on the “CRN 457” control module. A powder cloud fills up with an index varying from 0
to 12 (there is no corresponding display on the spray gun). On start-up of the spray gun, the powder flow
rate value is 0 (zero flow rate). It is possible to select the flow rate without having to press the trigger.
